玉米雄穗分枝性状的数量遗传分析
Quantitative Genetic Analysis of Tassel Branch Number Traits in Maize (Zea mays L.)
摘要
Abstract
Six generations of different plant type maize inbred lines Zi330 and PH4CV were used in the study, the tassel branch number was counted by eyeballing. P1, P2, F1, F2, B1 and B2 were used to study the inheritance of maize tassel branch number with joint analysis of multiple generations. The results were as follows: maize tassel branch number trait presented a two peak distribution in the F2 population, and a multi-peak distribution in the B1 and B2 populations, indicating that the trait was quantitative in nature and controlled by polygene. The inheritance of maize tassel branch number trait fitted the model of additive-dominance-epitasis polygene (C Model). The dominance played the leading role. The polygene heritability was higher between 74.83％ and 80.42％. If less tassel branch number inbred line was choosen basic materials must be started. The effects of polygene heritability were important on maize tassel branch number inheritance, and should be paid more attention in maize breeding.关键词
