Subspecific Differentiation of Rice Lines Derived from Indica/Japonica Cross Identified by InDel Markers

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.
