摘要
国际水稻遗传评价网提供的351份水稻材料,在四川泸州多表现为迟熟中稻类型。其中,播种至抽穗期稳定性较好的材料9份,单株有效穗>15穗的6份,千粒重>32g的3份,每穗着粒数>200粒的13份。单株有效穗、粒重和每穗着粒数、实粒数的变异系数>30%。
Three hundred and fifty one very early and early maturing rice accessions were introduced from International Network for Genetic Evaluation of Rice to Luzhou, Sichuan. The majority of the germplasms behaved as late maturing mid season rice under the local natural ecological conditions. Some promising germplasms were identified and screened, of which 9 showed good stability of the duration from sowing to heading, 6 had more than 15 productive ears per plant, 3 had a 1000 seed weight of > 32 g and 13 had > 200 grains per ear. The variation coefficients for productive ears/plant, seed weight, grains/ear and filled grain number were greater than 30%.
