^(60)Co-γ射线诱变选育早熟和高产及优质大豆新品种黑河52

Breeding of Soybean Cultivar Heihe 52 with Early Maturity,High Yield and Good Quality by Hybridization and ^(60)Coγ-ray Irradiation

1998年以黑河18为母本,绥97-7049为父本进行杂交,1999年用60Co-γ射线0.14 kGy辐照大豆F2风干种子,经多代按系谱法进行选择,选育成早熟、高产和适应性强的大豆新品种黑河52。于2010年3月通过黑龙江省农作物品种审定委员会审定并命名。该品种具有早熟、高产稳产、秆强、不炸荚、适应性广和适宜机械收获等突出特点,区域试验平均产量为2 092.6 kg.hm-2,比对照品种黑河43增产8.1%,生产试验平均产量2 420.4 kg.hm-2,比对照品种黑河43增产8.5%。该品种的成功选育表明辐射诱变与常规杂交相结合的育种技术是选育早熟高产优质大豆新品种的有效方法。

Soybean cultivar Heihe 52 was developed by the Fz hybird seeds of Heihe-18/Sui-97-7049 that treated by 0. 14 kGy ^60Co-γ-rays irradiation and was bred using pedigree breeding method in 1999. It processed the characters of early maturity,high yield,strong adaptability and was named by the Heilongjiang Crop Cultivars Approved Committee in March 2010. Its salient features were early maturity, high and stable yield, wide adaptation area and suitable mechanical harvesting. The average yield of Heihe 52 in the regional tests was 2 092.6 kg·hm^2, 8. 1% higher than the control variet Heihe 43 and the average yield in production was 2 420.4 kg·hm^2, increased by 8.5 % compared with the control variety Heihe 43. The results showed that irradiation combined with hybridization was an effective breeding approach to develop new varieties with the characters of early maturity,high yield and good quality.
