摘要/Abstract

摘要： 根据80个爆裂玉米自交系数量性状的表现估算了它们之间的遗传距离，又估算了由其中49个自交系间随机组配的67个杂交组合F1代小区产量、爆粒率和膨胀倍数的杂种优势。相关和回归分析表明，F1代产量的对照优势与其双亲间的遗传距离呈显著的二次曲线关系，而F1代品质特性爆粒率和膨胀倍数的对照优势与其双亲之间的遗传距离无确定

Abstract: An experiment was conducted in 1990 to 1991 at the university, to study the relationships between genetic distance, cluster analysis and heterosis in popcorn. Results showed that there is no much sense in clustering parental lines for prediction of heterosis, but blood pedigree may be identified fro

Key words: Popcorn, Genetic divergence, Heterosis
