Stigma exsertion in male sterile lines of hybrid rice is important for seed yield. In the present study, ZS616 [Oryza sativa subsp. Xian (indica)], a male sterile line with a stigma exsertion rate (SER) as high as 94.5%, was crossed to DS552, a japonica line with almost no exserted stigmas. F3 plants with extremely low and high SER were sequenced to identify SER-associated quantitative trait loci (QTL). A major QTL for SER, qSER-3.1, was identified along with other QTL on chromosome 3 in a 3.9 Mb region. A total of 307 nonsynonymous single-nucleotide polymorphisms (SNPs) and 27 frame-shift insertion/deletions (InDels) differentiating ZS616 and DS552 were identified in the region containing qSER-3.1. Most SNPs (294) and InDels (25) were excluded after further analysis because they were shared by ZS616 and low ( |
