水稻产量和抽穗期性状的配合力效应分析
Combining ability effects of yield and heading traits in rice
摘要
Abstract
Two sets of test crosses (Set 1 and Set 2), derived from the crosses between sixty inbred lines as its male parents and two sets of male sterile entries as female parents, respectively, were used to analyze the effects of general combining ability (GCA) and special combining ability (SCA) for yield and heading date. Set 1 was planted in two consecutive seasons (dry season, DS; wet season, WS) for the analysis. The ANOVA analysis results showed that GCA and SCA for the two traits were significantly different, respectively, meaning that GCA and SCA were co-controlled by additive genes and non-additive genes. Using Griffing Model I, variances of GCA and SCA were further estimated. In Set 2 (WS) , GCA values for grain weight per plant of female parents were higher than those of male parents, the SCA effect was higher than GCA effect of the parents; the contrary results were found in Set 1 (both in DS and WS). For heading date, GCA effect of the female parents was higher than that of male parents in dry season but no difference in wet season. The SCA effect was also higher than that of parents indicating that heading date was mainly affected by SCA. It was suggested that ecological rice breeding had to be adopted to stabilize and enhance rice yield.关键词
