摘要
采用完全随机区组试验设计,以主推常规品种晋谷21号为对照,对5个杂交谷子品种在太谷地区的产量表现及粗蛋白和总淀粉含量进行分析。结果表明,张杂谷3号、张杂谷5号、张杂谷9号、张杂谷10号杂交谷子品种的产量比对照晋谷21号增产32.08%～55.72%,且差异显著,;对照晋谷21号的品质优于参试的杂交谷子品种;穗质量、平均分蘖、产量、穗粗和单位面积有效穗数变异系数较大,茎粗和总淀粉变异系数较小;产量与平均分蘖、穗长和千粒质量呈正相关;粗蛋白与株高呈正相关;总淀粉与穗质量和株高呈正相关;主成分1,2,3对变异的累计贡献率达96.003 0%。
By the method of random complete block design,we have studied the yield performances of five hybrid millets compared with the Jingu 21,which are widely grown in the county of Taigu as check in this experiment.Results showed that there were remarkable differences in yield.The hybrid varieties of Zhang zagu millets all had higher yield than that of Jingu 21,the range of increasing in yield was 32.08%～55.72%.But Jingu 21 had better quality than the hybrid varieties of millet.The variation coefficients of spike weight,average tiller,yield,spike diameter and efficient panicle of unit-acreage were larger,while those of stem diameter and total starch were smaller.There was a positive correlation between the yield and average tiller,spike length and 1000-grain weight.The crude protein had significant positive correlations with plant height.The total starch had significant positive correlations with spike weight and plant height.The cumulative contribution rate of these principal components to variance was 96.00%.
