甜菜多粒雄性不育系及其保持系的配合力分析

Analysing on Combine Ability of Multigerm Male Sterile and O-type Lines in Sugar Beet

本文通过对5对不同亲缘的多粒雄性不育系和保持系配合力及其亲本基因型方差的分析,看出雄性不育系工农M214A及O—型系在根产量、含糖率、产糖量3个经济性状一般配合力较高;经回交3代成系的其它几对材料对上述多基因控制的3个性状,不育系与同型保持系间的表现并不一致。试验对亲本的配合力和遗传力作了初步分析,为利用杂种优势配制三交种提供了一些资料。

The combine ability of five pairs of different multigcrm male sterile (MS) and O-type lines, variance of parent's genotype were analysed in this paper. Understanding higher value of general combine ability of Gongnong 214 A (MS) and O-type in technical characters of root yield, sugar content and sugar yield. So, discovering different performance between MS lines and O-type lines through BC3 in the characters controlled of multigene, The expression were not identical within MS lines and within O-type maintainors. This test was preliminary analysis on the combine ability and heritability of parents. So as to provide some materials for application in hetcrosis breeding.
