以珍籼９７Ａ等６份籼型不育系和０２４２８等７份粳型广亲和系进行不完全双列杂交，对亲本及Ｆ１的柱头长等７个花器性状，根据加性一显性一母体效应模型（简称ＡＤＭ）采用ＭＩＮＱＵＥ（１）法进行遗传分析，结果表明柱头长和柱头外露率由加性、母体及显性作用共同控制；而柱头面积、花柱和柱头总长、小穗长、小穗长宽比则均以加性效应控制为主，母体效应不存在；包颈率则以母体效应控制为主。对籼型亲本基因效应值的研究表明，协青早Ａ和浙南１号Ａ有明显的增加柱头长度和柱头面积的加性效应，而红突Ａ则在提高柱头外在率方面具有良好的母体效应。对花器性状间遗传相关的分解表明，柱头长等五个性状间主要以加性与加性效应相关，并有一定的显性与显性相关。
Seven indica sterile lines of Zhen indica 97A and 7 Japonica wide compatibility lines such as 02428 were used for incomplete diallel crosses. Based on the additive-dominant-one The results of genetic analysis using MINQUE (1) showed that stigma length and stigma exsertion rate were controlled by additive, maternal and dominant effects. The stigma area, the total length of style and stigma, the length of spikelet, The spikelet aspect ratio was dominated by additive effect, maternal effect does not exist; neck rate is based on maternal effect control. Studies on the genetic effects of indica parents showed that Xieqingzao A and Zheonan 1 A significantly increased the additive effects of stigma length and stigma area, while Hong Zhu A significantly increased the stigma exsertion rate Maternal effect Genetic analysis of the floral traits revealed that the stigma length and other five traits were mainly related to additive and additive effects, with some dominant and dominant correlations.
