【摘要】 本研究应用RAPD技术对湄洲岛和平潭岛上4个烟豆小种群进行的生态遗传学研究,结果显示,总的多态位点比率为1.0,4个种群中最小为0.41,最大为0.82,表现出高度的多态性。利用相似系数及遗传距离进行的聚类分析结果表明,在种群间地理距离较大时,遗传分化与地理距离有一定的相关性,在小范围内则无明显相关性。更多还原

【Abstract】 The ecological genetic research on Glycine tabacina populations was based on RAPD technique,which revealed 100% polymorphisms,with minimum value of 0.41 in population MM,and maximum value of 0.82 in population PT.Cluster analysis showed that the populations’ genetic variation was correlation to the environment gradient when the geographic distance among populations was big.In small geographic range,however,no correlation exists between genetic structure and ecological factors because of random genetic drift.更多还原
