Subspecific Differentiation of Rice Lines Derived from Indica/Japonica Cross Identified by InDel Markers
-
摘要: 通过籼粳杂交培育了9个水稻品系, 进行形态指数法和分子标记法籼粳属性鉴定。结果表明, GY908、GY1128、GY1124和GY2888属籼稻类型, GY926和GY2750属偏籼类型, GY726、GY770、GY1134属偏粳类型, 与分子标记的遗传距离聚类分析结果一致。说明通过籼粳渐渗手段, 培育中间型水稻品系, 对丰富水稻新材料的遗传背景具有重要意义。Abstract: Nine lines were derived from the hybridization between indica and japonica rice.Meanwhile, the subspecific differentiation of the lines was analyzed by morphological index and InDel markers.The results indicated that the lines of GY908、GY1128、GY1124and GY2888 were attributed to the indica type, the lines of GY926 and GY2750attributed to hesien (indica) and the lines of GY726、GY770、GY1134attributed to the keng (japonica) type, similar to the cluster analysis of the genetic distance.The results showed that developed indica-japonica intermediate type of rice by the hybridization between indica and japonica rice had the great significance for enrich the genetic background of rice.
