- 摘要:
- 为促进黑龙江省西部风沙盐碱半干旱地区高产大豆品种选育,利用灰色关联度分析方法,对黑龙江省农业科学院大庆分院自育的14个品种(系)的大豆植株花、荚期生物量、产量及产量构成因素进行了综合分析。结果表明:单株粒重与产量的关联度(γ=0.739 0)最大,其次是单株粒数(γ=0.736 9)和花期根瘤干重(γ=0.719 2);关联度最小的是百粒重(γ=0.583 4);其他性状与产量的关联度都介于0.58~0.69。说明单株粒重、单株粒数和花期根瘤干重对产量的影响最大,百粒重与产量的关系最远,相对于其他性状对大豆产量的影响最小。因此在黑龙江省西部半干旱地区选育高产大豆品种时,应首先注重单株粒重、单株粒数和花期根瘤干重性状的选择。
- Abstract:
- In order to promote the selection and breeding of high-yield soybean varieties in the sand,salt and alkali semi-arid areas in the west of Heilongjiang Province,this paper made a comprehensive analysis of the biomass,yield and yield components of the 14 varieties (lines) of soybean in the flowering and podding period by using the method of grey correlation degree analysis,which were bred by Daqing Branch of Heilongjiang Academy of Agricultural Sciences.The results showed that correlation degree(γ=0.739 0)between seed weight per plant and yield was the highest,followed by seed number per plant(γ=0.736 9) and dry weight of nodule at flowering stage(γ=0.719 2),the lowest correlation degree was 100-seed weight(γ=0.583 4),and other traits were all between 0.58 and 0.69.Seed weight per plant,seed number per plant and dry weight of nodule at flowering stage had the greatest impact on yield,100-seed weight had the furthest relationship with yield,and had the least impact on soybean yield compared with other traits.Therefore,in the selection of high-yield soybean varieties in the semi-arid area of western Heilongjiang Province,we should first pay attention to the selection of seed weight per plant,seed number per plant and dry weight of nodule at flowering stage.
