Genetic analysis of genotype × environment interaction for yield components of E. canadensis,E.sibiricus and their hybrids

摘要

E.canadensis and E.sibiricus are plants whose combining ability and synthesis performance are all good.In this paper,genetic effect of fresh grass yield components of E.canadensis,E.sibiricus and their hybrids (F1 and F2 ) were studied in two different environments.It was known how the relative size of kinds of genetic diversity and genotype × environment interactions affect fresh grass yield.All these provided the theory basis for selection of traits in forage breeding for yield and the heterosis utilization of forage.
