%X A doubled haploid (DH) population derived from anther culture of F1’s between an Indica var. Zhai-Ye-Qing 8 and a Japonica var. Jing-Xi17 as well as two backcross populations derived from this DH population were used to investigate inheritance of the embryo sac abortion at early megagametogenesis occurring in Indica/Japonica rice crosses. Two major loci, dominant and complementaryesa-1 andesa-2, located on chromosomes 6 and 12 respectively, were detected. Genetic analysis indicated that embryo sac fertility is mainly regulated by the gametophytic genotype at these two loci.
