Genetic Integrity Analysis of Cotton (Gossypium hirsutum Linn.) Accessions Using SRAP and SSR Markers

利用SRAP和SSR分子标记检测29份棉花种质遗传完整性。结果表明,无论每一份不同更新发芽率水平繁殖后代的种质之间,还是每一份不同繁殖世代数种质之间,其等位基因频率差异不显著,也没有检测到稀有等位基因缺失的情况。本试验表明不同更新发芽率水平和繁殖世代数差异没有对棉花这种常异花授粉作物种质遗传完整性变化产生影响。

Genetic integrity of 29 cotton （Gossypium hirsutum Linn. ） accessions was analyzed using SRAP and SSR markers. It showed that the differences of allele frequency among the populations regenerated from the accession samples with different germination level or the populations obtained from the accession samples with different generations were not significant, and there was no absence of rare alleles observed. The result showed that the factors of different germination levels and generation times did not affect the genetic integrity during the regeneration in the case of often cross-pollinated crops like cotton.
