영문 초록

Early maturing glutinous rice lines with giant embryo were developed using anther culture. Deuraechan, mid-late maturing high-yielding japonica rice variety with resistance against rice stipe virus (RSV), bacterial blight (BB), and lodging, and Chenghyangna ge, early maturing glutinous rice germplasm with giant embryo were used the parents. F2 seeds from the cross between Deuraechan and Chenghyangna ge with glutinous endosperm and giant embryo were selected and propagated to F2 population. In F2 population, anther culture was conducted using the panicles from the early maturing plants. All doubled haploid (DH) lines showed early maturing, glutinous endosperm, and giant embryo phenotype. Through marker-assisted selections to Stvb-i and Xa3, 17 DH lines carrying both resistance genes were selected. Among 17 DH lines, six lines with more embryo size and better agronomic traits were selected and analyzed their characteristics. These lines were early maturing glutinous rice with giant embryo and showed enhanced yield, resistance against RSV and BB, and lodging, compared to previously developed giant embryo rice varieties. But they were vulnerable to preharvest sprouting which is important trait in early maturing rice. According to the texture and rapid viscosity analysis, DH lines were considered to have appropriate properties of cooked brown rice. They showed less hardness, gummniess, chewiness, and setback. Developed DH lines could be useful materials for diversification of cropping system and enhancing the brown rice consumption but the breeding efforts to improve the vulnerability against preharvest sprouting is required to apply for practical variety.
