摘要
以引进的11个谷子新品种为材料,采用渗水地膜穴播技术,对8个主要农艺性状进行了灰色关联度分析,综合评价了品种的优劣性。结果表明,参试品种主要农艺性状对产量的关联度值由大到小依次为穗数、生育期、穗长、穗粒重、穗重、千粒重、株高。通过等权关联度和加权关联度分析,结合生长期的抗病性、抗倒伏等抗逆性指标,筛选出适宜在当地种植的品种为张杂谷13、白良谷和黄金苗。
The introduction of 11 new millet cultivars were used as materials,all of which were planted by hole sowing with water permeable plastic film.The grey correlation analysis of 8 main agronomic characters of the tested varieties was carried out,and the advantages and disadvantages of the varieties were comprehensively evaluated.The results showed that the correlation degree of main agronomic traits to yield of the tested cultivars order from largest to smallest is ear number,growth period,ear length,grain weight per spike,spike weight,1000-grain weight and plant height.Through the analysis of equal weight correlation degree and weighted correlation degree,combined with the resistance indexes such as disease resistance and lodging resistance in the growing period,the cultivars suitable for local planting were selected as Zhangzaogu 13,Bailianggu and Huangjinmiao.
