Abstract
Cleistogamy is the self-pollination within closed spikelets and is expected to be a useful genetic tool for prevention of possible gene transfer in transgenic crops, for maintenance of genetic purity in autogamous crops, and for increased tolerance to biotic and abiotic stresses. Mapping of the gene ld(t), which is responsible for lack of lodicules inside spikelets and causes cleistogamy, was carried out using F2 and F3 populations derived from a cleistogamous (CL) mutant CL-SNU x Milyang 23 cross. A number of STS markers along chromosomes were developed and bulked segregant analysis was adopted for preliminary mapping. The results showed that the ld(t) was located at the end region of chromosome 1L, flanked by S01178b (an STS marker developed for the locus at 178 cM based on the rice genetic map reported by Japanese Rice Genome Project) at 0.8 cM and co-segregated with S01181a and S01181b (an STS marker developed for the locus at 181 cM).
