本文概述了从野生大豆进化到栽培大豆各个性状演化趋势。进化程度以产量性状最大;三种类型中以半野生型变异最大;各性状变异情况以荚大小、每荚粒数、全生育期变化最小,而单株荚数、粒数及粒重变异最大;从各性状相关分析看出:三种类型相关性均相似,其相关值大小可顺序排列为叶面积—叶宽>产量性状>全生育期—出苗到开花日数>植株性状。
This article outlines the evolutionary trends in the evolution of wild soybeans from cultivated soybean. The degree of evolution was the largest in yield traits; the variation in semi-wild type was the largest among the three types; the variation in traits was the smallest in pod size, per pod grain number and full growth period, while the variation in pod number, grain number and grain weight per plant was the largest According to the correlation analysis of the traits, the correlations of the three types were similar. The correlation values were arranged in order of leaf area-leaf width> yield traits> whole growth period-emergence to flowering days> plant traits.
