黑龙江省不同地区大豆种质资源农艺性状的表现及相关性

Analysis of Represent and Relation on the Agronomic Characters of the Germplasm Resources of Heilongjiang Soybean

为促进高产优质大豆的亲本选配及相关优良性状的选择,对75份黑龙江省不同地区选育的大豆种质资源进行主要农艺性状分析。结果表明:黑龙江省不同地区选育的大豆种质资源的平均表现及遗传变异不同;试验品种的诸多农艺性状间具有一定的相关性;在黑龙江省选育大豆新品种时应综合考虑不同地区农艺性状特点及遗传潜力大小。

In order to promote the parent selection of high yield and high quality soybean and the selection of related good traits,this study analyzed the main agronomic traits of 75 soybean germplasm resources selected from different regions of Heilongjiang Province.The results showed that the average performance and genetic variation of soybean germplasm resources selected in different regions of Heilongjiang province were different.There were certain correlations between many agronomic traits of the tested varieties.It should be selected when breeding new soybean varieties in Heilongjiang province consider comprehensively the characteristics of agronomic traits and the genetic potential of different regions.
