黑龙江省西部大豆产量相关性状的分析

Analysis on Yield Correlated Traits of Soybean in the West of Heilongjian Province

为了解大豆主要农艺性状的遗传实质和相关变异,评价对产量间接选择的重要性,为黑龙江省西部大豆品种选育提供科学理论依据,以6个熟期和结荚习性不同的大豆品种(系)为试材,研究大豆6个农艺性状的遗传力、遗传相关和遗传进度。结果表明:提高黑龙江省西部大豆产量,必须有适当的株高,并确保有足够的节数和单株粒数。

In order to understand the genetic essence and correlative variance of main traits of soybean,estimate the importance of indirect selection on yield,and provide scientific basis for soybean breeding for western of Heilongjiang,six different maturity and poding habit varieties（strains） were taken as materials to study the heritability,genetic correlation and genetic progress of the six economic traits of soybean.The results demonstrated that there must be suitable plant height,adequate node number per plant and grains number per plant for increasing soybean yield in the west of Heilongjian province.
