摘 要: | 利用SRAP技术对36份茄子栽培种进行遗传多样性分析。结果表明:22对引物对36份茄子DNA进行PCR扩增,经过染色后共获得292条多态性条带,平均每个引物组合扩增出13.27条多态性条带。36份茄子品种间遗传相似系数在0.568~0.870,平均遗传相似系数为0.757,这表明该群体的遗传背景相对狭窄。利用UPGMA法对36份茄子资源进行聚类分析,结果显示,在相似系数为0.690处,可将36份茄子资源划分为5个组。

Abstract: | The genetic diversity of 36 eggplant was analyzed by SRAP maker. Two hundred-ninety-two polymorphic bands were amplified by 22 SRAP primers with an average of 13.27 polymorphic bands per primer pair. The genetic similarity was from 0.568 to 0.870 with an average genetic similarity w 0.757. The result suggested that the genetic diversity of 36 eggplants was related narrow. Thirty-six eggplants were clustered into 5 groups at 0.690 coefficients by UPGMA method. |
