不同产地大豆种质资源农艺性状的表现与相关性分析

将来自不同产地的377份大豆种质资源分别在北京农学院试验田种植,并对它们的15个主要农艺性状在北京地区的表现进行研究分析。结果表明:(1)不同产地的大豆地方种质资源群体农艺性状在北京的平均表现及遗传变异度不同,系统选育新品种时应根据各地区农艺性状的特点及遗传潜力的大小分地区进行;(2)供试品种的诸农艺性状间存在着一定的相关性;(3)以在北京农学院试验地种植的不同产地的大豆品种群体为背景,进行系统选育新品种时,若以全生育期对荚长、单株荚数、单株粒数进行直接选择可望获得早熟、高产新品种,若以荚长、荚宽进行间接选择可望获得大粒新品种。

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

This paper presents an analysis on the behavior of 15 main agricultural characters of the of 377 soybean varieties from the different producing areas.The results indicate:(1)The average behavior and hereditary variability of agricultural characters of idioplasmatic resources of soybean varieties from different producing areas are different in the Beijing region,the systematic development of new varieties must be selected by regions according to the agricultural characters and hereditary potential;(2)There are some correlations in the agricultural characters of the test varieties;(3) On the situation of systematic development of new soybean varieties in Beijing region from varieties of different producing areas,the new variety of premature and high yield is expected to be selected directly by the pod length,pod number and grain number of individual plant in the full bearing period,the new variety of big grain is expected to be selected indiredly by pod length and pod width.
