Soil and plant samples were taken from experimental sites randomly, and were analysed in laboratory to plant available Zn^2＋） content. Zinc ＂Zn（2＋）＂ concentrations showed a large variability to interactions with soil＇s pH values. It ranged from 0.4 and 1.36 mg kg1. Soil＇s ＂Zn（2＋）＂ contents had been significantly lower than International Soil Limit （ISL） value （70 mg kgl）, consequently. Plant available ＂Zn（2＋）＂ contents from triticale rhizosphere soils in Leaf＋Straw ranged from 10.1 to 38.4 mg kgl, and in Seed from 26.9 to 52.0 mg kg1. ＂Zn（2＋）＂s Actual Translocation Index （ATI） from rhizosphere soils to Leaf＋Straw had as average 23.6, and to grain 43. 1. ＂Zn（2＋）＂ Leaf＋Straw bioacummulation （g hal） had as average 13.4, Grain 23.2, and total （Leaf＋Straw＋Grain） 36.6. ＂Zn（2＋）＂translocation from soils to Leaf＋Straw was 37% lower than to Grain. Ultimately, within the range of experimental conditions tested these results are present that ＂Zn（2＋）＂ tends to accumulate to triticale organs to create the conditions for toxicity effects in Food Chane.展开更多

Phenot^ing showed that frequencies of soft, mixed and hard genotypes were 43.3%, 48.3%, and 8.4%, respectively. Genotyping identified three known secaloindoline-a alleles and four known secaloindoline-b alleles. Three new Sina-Rl alleles were designated Sina-Rld, Sina-Rle and Sina-Rlf. Compared to Sina-Dlc, Sina-Rld showed four point mutations causing changes in four amino acids, Sina-Rle had one point mutation causing an alanine to glycine substitution, and Sina-Rlf possessed five point mutations but produced the same amino add sequence as Sina-Rld. Two new Sinb-Rl alleles were discovered and designated Sinb-Rle and Sinb-Rl/. Compared to Sinb-Rla, Sinb-Rle possessed a triplet-code insertion and four point mutations causing a cysteine insertion and two amino acid substitutions, and Sinb-Rl/possessed three point mutations causing a cysteine insertion and a change of arginine to glycine.Association of hardness index with secaloindoline alleles indicated t±iat SKCS of the Sina-Rld genotype was significantly lower than that of Sina-Rle, and Sinb-Rle was significantly lower than that of the Sinb-Rld genotype. A total of eight allelic combinations of secaloindoline genes were identified; Sma-Rld/Sinb-Rle and Sina-Rle/Sinb-Rld were relatively prevalent in the triticales surveyed. The results provide valuable information for further use of these germplasms in triticale breeding program due to the diverse polymorphism in secaloindoline genes.展开更多
Twenty lactating cows of two to five parity having an average live weight of 290.00 to 330.00 kg and an average milk production of 4.54 kg/head/day to 4.66 kg/head/day were selected from the Central Cattle breeding St...Twenty lactating cows of two to five parity having an average live weight of 290.00 to 330.00 kg and an average milk production of 4.54 kg/head/day to 4.66 kg/head/day were selected from the Central Cattle breeding Station and Dairy Farm. The four dietary treatment were： SlooTo （Straw 100： Triticale 0 as control）; $5oT5o （Straw 50： Triticale 50）; $25T75 （Straw 25： Triticale 75） and SoTloo （Straw 0： Triticale 100）. It was observed that the roughage dry matter intake （DMI） （2.61 ~ 0.07 kg） in percent live weight was significantly （P 〈 0.05） higher in $25T75 and the lowest （1.76 ~ 0.018 kg） in the control group （SlooTo） and the differences were significant among the dietary treatments except $5oT5o and SoTloo. The total DMI was significantly （P 〈 0.05） higher in SoT^oo （13.36 i 0.13 kg） followed by $25T75, $5oT5o and SlooTo, respectively. The digestibility of crude protein （CP） was slightly higher in $25T75 （75.48 ~ 0.96） compared to SoTtoo （75.31 ~ 1.45） and the difference was non-significant （P 〉 0.05）. Milk production was significantly （P 〈 0.05） the highest in $5oT5o and the lowest in SlooTo followed by SoTloo, $25T75, respectively. The percent increased in milk yield was also the highest in $5oT5o （67.68%） and the lowest in SlooTo （28.85%）. The 4% fat corrected milk was also significantly （P 〈 0.05） higher in $5oT5o followed by SoTloo, $25T75 and SlooTo, respectively. Therefore, it can be concluded that triticale and straw at a ratio of 50：50 may be fed for better production performance of dairy cows.展开更多

The breeding method applied for the recombinant secondary hexaploid triticale proved to be effective since the favourable traits of wheat, durum wheat and rye were successfully combined in the genome of the new cultivar. The first aim was to characterize the genome composition. Multicolour genomic in situ hybridization (mcGISH) was used for the genome compositional analysis. According to the results, the cultivar contains the wheat AB genome (AABB = 28 chromosomes) and the whole rye (R) genome (RR = 14 chromosomes). The presence of D genome, however, could not be detected within the detection limit of the GISH method. Hungaro is the very first triticale in Hungary that has been used for human consumption (milling industry, baking industry, pasta production). In this study, amino acid content of flours was measured. Amino acid investigations on Hungaro durum rye’s flour showed that the quantity of essential amino acids, especially of methionine and cysteine, are higher in Hungaro durum rye than in the also investigated Ryefood rye cultivar and the GK ?thalom wheat cultivar. The genes inherited from the wheat species ensure high yield and great baking and dough making qualities. Therefore, its flour is suitable in itself for pastry and dough production (without mixing it with other flours). Its characteristics inherited from rye guarantee excellent abiotic and biotic resistance.展开更多

The agronomic traits and grain yields of 13 primary 6x Tritipyrum lines were evaluated and compared with five modern 6x triticale lines and nine bread wheat cultivars at Bahonar University, Kerman, Iran in a completely randomized block design with three replications. The primary Tritipyrum lines increased the grain yield per plant by 2.8% and 14.1% compared to triticale promising lines and Iranian bread wheat cultivars, respectively. Although the primary Tritipyrum lines were late maturing, they were shorter than the triticale lines and wheat cultivars and superior in many characters such as penultimate leaf area, flag leaf length, penultimate leaf length and time to milky ripeness. Genotypes were divided into four groups for agronomic and morphological traits and four groups for grain yield by cluster analyses. All clusters showed significant differences （a = 5%） for all traits and the first cluster, which comprised primary Tritipyrum lines, had a higher mean grain yield than the other clusters. The results of this first large-scale trial indicated the high adaptation of primary Tritipyrum lines to conditions in Kerman province in South-east of Iran.展开更多

A factorial experiment was done based on the randomized complete blocks design with 4 replications. The first factor was three levels of clipping stages including non-clipping, clipping at tillering and booting stages. Different levels of nitrogen fertilizer including 0, 40, 80, 120 and 160 kg/ha were arranged at the second factor. Results showed that non-clipping and clipping at booting stage with 610.5 and 203.1 g/m2 had the most and the lowest grain yield, respectively. The highest economical proficiency (3743.06 $/ha) resulted with using 80 kg/ha nitrogen fertilizer and non-clipping. With considering both forage and grain yield, it is necessary that the clipping should be done at tillering stage with using of 120 kg/ha nitrogen fertilizer (3336.56 $/ha). At regression of economical proficiency traits of grain yield, straw and total dry matter remained at the final model. Economical proficiency had the significant positive correlation with spike per square meter (0.87**), grain yield (0.64**), total dry matter (0.65**), plant height (0.52**) and 1000-kernal weight (0.54**).展开更多

The experiment was set up on a luvisol medium soil, derived from light loam with the objective of evaluating the response of two winter triticale varieties （Pigmej and Cyrkon） to cultivation without protection （O）, chemical weed control （H） and combined protection against weeds and fungi （HF）. Comparisons were made in two crop sequence systems： cultivation of winter triticale varieties in a 6-field crop rotation and cultivation in a 19-23-year-long monoculture. The results showed that the plant sequence system significantly differentiated the response of winter triticale varieties to the applied levels of field protection. Significantly higher grain yield gains of the winter triticale varieties in response to the application of herbicides or herbicides with fungicides were obtained in the monoculture than in the crop rotation. In the crop rotation, a higher increase in yields induced by the applied plant protection treatments was achieved by the variety Cyrkon. In the monoculture, the response of both varieties to the herbicides applied was nearly identical, while the combined application of herbicides and fungicides raised the yields of var. Pigmej higher than those of var. Cyrkon. Overall for the plant protection levels, var. Cyrkon yielded higher than var. Pigmej by 18.1% more in the crop rotation and by 26.9% in the monoculture. At the same time, var. Cyrkon demonstrated a weaker response to being grown in the monoculture than var. Pigmej did. The average yield of the former was reduced by 21.1%, whereas the latter yielded 26.6% less grain.展开更多

The discovered structure of the collection was as follows: 50.0% and 41.7% of the collection carries Vp-1Bа and Vp-1Bc alleles, respectively, while 8,3% possesses both of them. As a result of the seed color estimation, the collection has been divided into two groups: with dark red seeds and light red seeds. The allele Vp-1Bc has appeared to be associated with PHS resistance while Vp-1Ba with PHS susceptibility in the triticale accessions with light red seeds only. The influence of the seed color and allelic state of Vp-1B on PHS resistance in triticale is discussed.展开更多

This study examined whether planting a legume-based winter cover crop mix offsets fertilizer application via natural nitrogen inputs. The influence of the cover crop mixture on available nutrients was also assessed. Hairy vetch (<em>Vicia villosa</em>) and winter triticale (×triticosecale) cover crops were planted in fall and terminated in May. Soil fertility data was collected before and after planting the winter cover crop to determine the effect on fixing nitrogen and soil phosphorus, potassium and organic matter levels. Increases of soil ammonium were observed in plots with cover crop treatments. A triticale-hairy vetch cover crop mix was successful at scavenging P for future crops and appears to hold promise for long-term soil fertility benefits.展开更多

文摘The novel salt-tolerant cereal, primary Tritipyrnm, is the third artificially synthesized crop plant. The agronomic traits and grain yields of 13 primary 6x Tritipyrum lines were evaluated and compared with five modern 6x triticale lines and nine bread wheat cultivars at Bahonar University, Kerman, Iran in a completely randomized block design with three replications. The primary Tritipyrum lines increased the grain yield per plant by 2.8% and 14.1% compared to triticale promising lines and Iranian bread wheat cultivars, respectively. Although the primary Tritipyrum lines were late maturing, they were shorter than the triticale lines and wheat cultivars and superior in many characters such as penultimate leaf area, flag leaf length, penultimate leaf length and time to milky ripeness. Genotypes were divided into four groups for agronomic and morphological traits and four groups for grain yield by cluster analyses. All clusters showed significant differences （a = 5%） for all traits and the first cluster, which comprised primary Tritipyrum lines, had a higher mean grain yield than the other clusters. The results of this first large-scale trial indicated the high adaptation of primary Tritipyrum lines to conditions in Kerman province in South-east of Iran.
文摘In order to reach suitable forage clipping and estimate nitrogen fertilizer to most economical proficiency, an experiment was carried out at Saatlo Station in 2008-2009 seasons. A factorial experiment was done based on the randomized complete blocks design with 4 replications. The first factor was three levels of clipping stages including non-clipping, clipping at tillering and booting stages. Different levels of nitrogen fertilizer including 0, 40, 80, 120 and 160 kg/ha were arranged at the second factor. Results showed that non-clipping and clipping at booting stage with 610.5 and 203.1 g/m2 had the most and the lowest grain yield, respectively. The highest economical proficiency (3743.06 $/ha) resulted with using 80 kg/ha nitrogen fertilizer and non-clipping. With considering both forage and grain yield, it is necessary that the clipping should be done at tillering stage with using of 120 kg/ha nitrogen fertilizer (3336.56 $/ha). At regression of economical proficiency traits of grain yield, straw and total dry matter remained at the final model. Economical proficiency had the significant positive correlation with spike per square meter (0.87**), grain yield (0.64**), total dry matter (0.65**), plant height (0.52**) and 1000-kernal weight (0.54**).
文摘Five-year trials （2011-2015） were accomplished in a continuous field experiment conducted at the Production and Research Station in Balcyny. The experiment was set up on a luvisol medium soil, derived from light loam with the objective of evaluating the response of two winter triticale varieties （Pigmej and Cyrkon） to cultivation without protection （O）, chemical weed control （H） and combined protection against weeds and fungi （HF）. Comparisons were made in two crop sequence systems： cultivation of winter triticale varieties in a 6-field crop rotation and cultivation in a 19-23-year-long monoculture. The results showed that the plant sequence system significantly differentiated the response of winter triticale varieties to the applied levels of field protection. Significantly higher grain yield gains of the winter triticale varieties in response to the application of herbicides or herbicides with fungicides were obtained in the monoculture than in the crop rotation. In the crop rotation, a higher increase in yields induced by the applied plant protection treatments was achieved by the variety Cyrkon. In the monoculture, the response of both varieties to the herbicides applied was nearly identical, while the combined application of herbicides and fungicides raised the yields of var. Pigmej higher than those of var. Cyrkon. Overall for the plant protection levels, var. Cyrkon yielded higher than var. Pigmej by 18.1% more in the crop rotation and by 26.9% in the monoculture. At the same time, var. Cyrkon demonstrated a weaker response to being grown in the monoculture than var. Pigmej did. The average yield of the former was reduced by 21.1%, whereas the latter yielded 26.6% less grain.
文摘The core collection of red-seeded winter hexaploid triticale with different pre-harvest sprouting (PHS) resistance has been evaluated for the allelic structure of the gene VIVIPAROUS-1B (Vp-1B) with STS molecular marker. The discovered structure of the collection was as follows: 50.0% and 41.7% of the collection carries Vp-1Bа and Vp-1Bc alleles, respectively, while 8,3% possesses both of them. As a result of the seed color estimation, the collection has been divided into two groups: with dark red seeds and light red seeds. The allele Vp-1Bc has appeared to be associated with PHS resistance while Vp-1Ba with PHS susceptibility in the triticale accessions with light red seeds only. The influence of the seed color and allelic state of Vp-1B on PHS resistance in triticale is discussed.
文摘Over-application of fertilizer to cropland adversely affects both environmental and agricultural ecosystems. This study examined whether planting a legume-based winter cover crop mix offsets fertilizer application via natural nitrogen inputs. The influence of the cover crop mixture on available nutrients was also assessed. Hairy vetch (<em>Vicia villosa</em>) and winter triticale (×triticosecale) cover crops were planted in fall and terminated in May. Soil fertility data was collected before and after planting the winter cover crop to determine the effect on fixing nitrogen and soil phosphorus, potassium and organic matter levels. Increases of soil ammonium were observed in plots with cover crop treatments. A triticale-hairy vetch cover crop mix was successful at scavenging P for future crops and appears to hold promise for long-term soil fertility benefits.
