小麦产量三因子最佳组合及其选择

Optimal Combination and Its Selection of Three Yield Factors in Wheat

通过对小麦产量组合三因子的分级及数据标准化,研究了产量最佳组合及其选择判断方法。采用难度系数、标准差作为选择标准,决定产量组合优劣。根据产量目标要求,通过查找难度系数低、因子聚集度小的产量因子组合,可确定三因子最佳指标,从理论上明确了育种的目标性状。

The optimal combination and its selective methods were studied by grading three factors of wheat yield and normalizing data. The difficulty coefficient and standard deviation were used to evaluate the yield combination of wheat. Based on the yield goal, the optimal combination could be ascertained by using the lower difficulty coefficient and smaller congregation degree of factors, and then the breeding goal was defined in theory.
