Estimates of combining ability for vegetative stage cold tolerance in rice
알 엔 카우(R. N. Kaw),로미 엠 비스페라스(R. M. Visperas),Huhn Pal Moon(文憲八),Jong Doo Yae(芮種斗) 한국육종학회 1986 한국육종학회지 Vol.18 No.1
Ninety F₁ rice hybrids were evaluated for combining abilily for low-temperature tolerance at the vegetative growth stage. Evaluation was done by subjecting the plant to 17℃ and 20℃ water temperatures in separate blocks from 20 days afler transplanting to maturity. Combining ability analysis showed the predominance of additive gene action. The Japonica parents viz. Shimokita, K48, SR5204-91-4-1, Stejaree 45, Barkat and K332 were good donors for vegetative stage cold tolerance. The best sca combinations involved both high and low general combiners. Parental performance per se was a good indicator of gca effects of the parents.
Estimates of combining ability for cold tolerance at reproductive stage in rice
램 나스 카우(Ram Nath Kaw),Huhn Pal Moon(文憲八),Jong Doo Yae(芮鍾斗),로미 엠 비스페라스(R.M. Visperas) 한국육종학회 1989 한국육종학회지 Vol.21 No.3
Ninety F₁ rice hybrids, produced by crossing 15 rice cultivars having lowtemperature tolerance at different growth stages with 6 high yielding elite IRRI cultivars, were evaluated for combining ability for reproductive stage cold tolerance. Evaluation was done by subjecting the plants to 17℃ and 20℃ water temperatures, in separate blocks, from 20 days after transplanting to maturity. Both general (GCA) and specific (SCA) combining ability variances were significant, with estimates of GCA being larger for all traits, showing predominance of additive type of gene action. The indica parents viz. Samgangbyeo, Suweon 287, Shoa-Nan-Tsan, K 39-96, China 988, IR 9202, Leng Kwang, IR 7167 and IR 15889 proved to be good donors for reproductive stage cold tolerance. Parental performance per se was a good indicator of general combining ability effects of the parents, but no association was observed between per se performance of the crosses and their specific combining ability effects.
