摘要： 用两个小麦杂交组合的 P1、P2、F1、F2、B1、B2和 F37个世代,用世代均数分析研究了小麦的剑叶面积,第二叶及第三叶面积,单穗粒重和谷叶比的遗传,用加权最小二乘法估算了遗传参数。结果表明,加性效应表现了极为显著的作用,显性效应也是显著的,

Abstract: The method of weighted least square analysis was used for generationmeans of seven populations-P1,P2,F1,F2,B1,B2,and F3 of two wheat(Triticum aestivum L.)crosses in the evaluation of gene effects on the inh-eritance of grai
