摘要： 本试验采用广义、狭义、方差分析、回归和相关5种方法估算的性状遗传力。其高低的位次趋势基本一致,即株高的遗传力最高,开花期、主穗长、二百粒重次之,结实小穗数、主穗重、每穗粒数再次之,单株粒重和单株穗数最低。在混合群体中,一般的性状直至 F4遗传力仍然较低。系谱选择法至 F4,一般性状系统间较

Abstract: The heritability of major economic characters was studied in F2 toF4 progenies of six wheat crosses.Heritability values obtained fromdifferent methods of estimation and their reliability were determined bycomparing the predicted genetic gairis with those actually obtained in th
