利用空间诱变技术选育大豆新品种克山1号

Developement of A New Soybean Variety 'Keshan No.1' by Using Space-induced Mutation

为了创新大豆品种和探讨育种技术,本研究通过空间诱变有性杂交F2,采用系谱选育方法,育成大豆新品种克山1号。该品种油分含量21.82%,蛋白质含量38.04%,2007-2008年参加国家早熟组区域试验平均产量2629.5 kg·hm-2,较对照品种黑河18号增产11.4%;生产试验平均产量2643.8kg·hm-2,较对照品种黑河43号增产6.9%,位列第一。采用shukla稳定性方差分析,克山1号产量稳定性好。2009年由国家农作物审定委员会审定(国审豆2009002)。该品种突出特点是早熟、优质、高产、稳产性好,适应性广,适合黑龙江省北部、吉林省东部山区、新疆北部和内蒙呼伦贝尔中部和南部地区春播种植。

To innovate soybean varieties and explore breeding techniques, the sexual F2 generation of space mutation was used in this study, pedigree breeding method was applied to develop a new soybean variety ＂Keshan No.1＂. The oil content of the variety was 21.82%, the protein content was 38.04%, the average yield was 2629.5 kg·hm-2 in early group of the national region testing during 2007-2008, the yield of Keshan No.1 was 11.4%;higher than that of the control （HeiheNo.18）, the average yield was 2643.8 kg·hm-2 in production testing, the yield of Keshan No.1 was 6.9% higher than that of the control （HeiheNo.43）, it ranked the first place. Using shukla stability variance analysis, the yield of Keshan No.1 was stable, Keshan No.1 was approved by the National Crop Examination Committee （National examination：2009002） in 2009, the prominent characteristics of this variety are early-maturity, good-quality, high -yield, good yield-stability and wide-adaptability, Keshan No.1 is suitable for planting in the northern part of Heilongjiang Province, the eastern mountain areas of Jilin Province, the northern part of Xinjiang and the central areas and southern areas of Inner Mongolia Hulunbeier in spring season.
