Abstract

Three cytoplasmic male sterile (CMS) lines were developed through the hybridization of indica and japonica rice. 064A and Xieyan A are wild abortivetype CMS lines, and 300S is a photo(thermo)sensitive male sterile line. By using morphological index and RFLP markers, the subspecific differentiation of the male sterile lines were detected. The morphological indexes for 064A, Xieyan A and 300S were 11, 9 and 12, respectively, attributing to the indicalinous type. The analysis of RFLP markers showed that these three lines were clustered into one class, similar to that by morphological index. The results indicate that these male sterile lines have proportional japonica pedigree on their indica genetic background. Some F1 between these three male sterile lines and restorer lines with wide genetic bases performed very strong heterosis in yield and applicable potential in super hybrid rice breeding program.

Key words： indica/japonica hybridization; morphological index; molecular marker; super hybrid rice
