摘要/Abstract

摘要： 本文用3个不育系与10个恢复系为供试材料，组成3×10NC II交配设计，对三系杂交稻谷粒性状进行了遗传分析。其结果，谷粒长、宽、长/宽和千粒重等四个性状均为加性基因效应起主导作用；谷粒的长/宽主要受母本（不育系）的影响，父本（恢复系）影响极小，未达显著水平；粒长、宽和千粒重三性状同时受父母本的影响，而且其影响

Abstract: At the present paper, a 3×10 incomplete diallel cross was carried out for studying the inheritance of the grain characters. The results showed that, the grain length , width, Length/width and 1000-grain weight all were mainly governed by the additive gene effects; Length/width were determined by th

Key words: Three-line hybrid rice, Grain characters, Inheritance and correlation, NC II cross design
