| 摘 要： | 利用40对SSR标记引物分析了豫综5号和金皇后综合种的遗传变异.结果表明:40对引物在两群体中都扩增出115个多态位点;累加40对引物扩增的基因型种类,豫综5号196种,金皇后194种;豫综5号的平均遗传距离为0.383 4,金皇后综合种为0.339 7;豫综5号的平均观察杂合度是0.382 6,平均期望杂合度是0.474 7;金皇后综合种的平均观察杂合度是0.329 2,平均期望杂合度是0.414 3.从以上结果来看,豫综5号的遗传变异较丰富.

| Abstract: | The genetic variation of Yuzong 5 and Gold queen maize population was analyzed by SSR molecular marker.The results showed that: 115 polymorphic loci from Yuzong 5 and Gold queen maize population were amplified by 40 SSR primers;the genotypic number accumulated by 40 primer amplification were 196 for Yuzong 5 and 194 for Gold queen;the mean genetic distances were 0.383 4 for Yuzong 5 and0.339 7 for Gold queen;the mean observed heterozygosity was 0.382 6 for Yuzong 5 and 0.329 2 for Gold queen,while their mean anticipant heterozygosity was 0.474 7 and 0.414 3,respectively.The results suggested that the genetic variation of Yuzong 5 is more abundant than that of Gold queen maize population. |
