Genetic effects analysis for grain traits of indica rice

摘要

Genetic effects analysis of grain traits was conductedbased on the additive-dominance genetic model(Zhu, 1992, 1993)for the quantitative traits. In-complete diallel crosses from early season indica rice(Oryza sativa L.)were made using eight parentswith short grain shape(Guanglu'ai 4 et al.)as fe-males andfive parents with long grain shape(Xi-angzaoxian 3 et al.)as males. F_1 seedlings and
