AFLP Analysis for Some Japonica Rice from Taihu Lake Region

Abstract

Abstract: Twenty four japonica rice cultivars from Taihu Lake Region were investigated by amplified fragment length polymorphism (AFLP) analysis. The genetic interpenetration of local cultivars into high yield commercial cultivars was analyzed based on AFLP data. The rusults showed that there was more inheritance distance among commercial cultivars than local cultivars. More genetic components of commercial cultivars came from other germplasm outside Taihu Lake Region but from local cultivars. The results agree with genealogy analysis for high yield commercial cultivars.

Key words: amplified fragment length polymorphism, japonica rice, local cultivar, commercial cultivar, interpenetration

摘要： 研究了24份太湖流域粳稻品种的AFLP，根据AFLP资料分析了太湖流域粳稻地方品种在推广品种中的渗透情况，结果表明大部分江、浙推广品种与地方品种间存在着相对较大的遗传距离，即地方品种在推广品种中的遗传组分较小，相反渗透进了较多的其他种质的遗传组分,这与推广品种的系谱分析结论一致。
