摘要

Genetic diversity is reduced from wild soybean to cultivars and from landraces to modern varieties. However, intraspecies genetic diversity loss between characters or phenotypes also existed in wild soybean. We revealed the phylogenic relationship of character types in Chinese wild soybean using 42 SSR markers. We conjectured that white flower, no-seed bloom, grey pubescence, and four seed coat colours were evolutionarily acquired phenotypes. There were a small decrease (∆H = 0.1–6.46%) of gene diversity and a moderate reduction (∆Na = 10.81–53.54%) of number of alleles but a violent loss (80.74–98.59%) of unique alleles in the acquired phenotypes. Our results seemed to suggest that ovoid and elliptic leaves were differentiated at the earliest and subsequently lanceolate leaf appeared before the domestication of soybeans within wild soybean, and that G. gracilis type was another earliest type, maybe emerged since the appearance of soybeans or it was concomitant with the domestication of soybean.
