| Abstract: | Hybrid sterility between indica and japonica subspecies in rice is basically caused by partial abortion of gametes and hybrid fertility could be recovered by a single
wide compatibility (WC) allele. In this study, a typical indica germplasm source of rice, UPRI 95-162, with strong wide compatibility
in cross with japonica rice was studied for location of its WC locus. Bulked segregant analysis was performed and SSRs (simple
sequence repeats) were conducted on a F1 population derived from a three-way cross (UPRI 95-162/T8//Akihikari). The locus was located on chromosome 1 approximately
0.2 cM to SSR markers RM581 on one side and 1.5 cM to RM292 on another. This WC locus, tentatively designated as S-20
n
(t), and its tight linkage markers, RM581 and RM292, would be very useful for efficient marker-assisted selection for breeding
new WC varieties and for map-based cloning of the gene. |
