摘要
用陕西省关中小麦品种区域试验所选用的 1 2个小麦品种 (品系 )在 1 2个试点的数据资料 ,分析了品种、环境及品种与环境互作 (CEI)对籽粒硬度、蛋白质含量、沉淀值及湿面筋含量的影响。结果表明 :基因型效应对所有品质参数均有显著影响。基因型与环境互作对沉淀值影响较大 ,而对籽粒硬度、蛋白质含量与湿面筋含量影响较小。环境效应对湿面筋含量和籽粒硬度影响较大 ,而对蛋白质含量与沉淀值影响较小。蛋白质品质参数的回归系数 (b值 )表明 ,基因型对不同环境的反应存在着显著差异。对于籽粒硬度、蛋白质含量与湿面筋含量回归偏差显著的品种很少 ,这表明线性回归模式占了基因型变异的绝大部分。一些品种的沉淀值显著偏离了回归。上述结果表明 ,要改善小麦品种的蛋白质品质 。
The study was to determine relative contributions of genotype, environment and genotype by environment interaction to variation in protein quality property of winter wheat variety,by the datum analysis of twelve winter wheat genotpyes at thirteen locations from regional trails of winter wheat variety in Guanzhong,Shaanxi province.Genotypes were found to significantly influence on variation in all protein quality parameters.Genotype and environment interactions were relatively larger for sedimentation value,but were smaller for kernel hardness,protein content and wet gluten content.Environmental effects had notably larger influence on variation in wet gluten content and kernel hardness compaed with protein content and sedimentation value.Significant differences among genotype response to environments were observed in the linear regreesion coefficients ( b values) for each quality parameter.There were few instances of significant deviations from regression in quality parameters of kernel hardness,protein content and wet gluten content,indicating that the linear model accounted for much of the variation in genotype response.But some varieties had significant deviation in sedimentation value.Based on these results,environmental influences on protein quality attributes should be an important consideration in variety improvement efforts toward enhancing protein quality of winter wheat variety.
