中文摘要:
      旨在选育多四粒荚大豆品种,构建理想模型,为大豆高产超高产育种探索新途径。用spss 18 分析‘汾豆96’生理生态特性,以椭圆叶形多四粒荚‘汾豆96’为主,结合34 份披针叶形四粒荚材料,对其10 项产量相关的农艺性状用逐步回归法构建理想模型。‘汾豆96’群体内四粒荚单株的存在率达85%以上,单株四粒荚最高达49 个,占总荚数的30.25%,‘汾豆96’产量随四粒荚数的增加总体呈增加趋势。当R2=0.939 时,模型拟合最优:Y=-87.583+0.415X1-5.155X2+10.094X3+13.459X4。回归方程表明多四粒荚创新材料产量与生物产量(X1)、株高(X2)、百粒重(X3)和主茎节数(X4)呈显著线性回归关系。提升每荚粒数和选育多四粒荚品种,是高产超高产育种产量突破的新途径。大豆品种具备的理想模型是抗倒伏、多荚粒、适合机械化收获的短节间密荚类型。
英文摘要:
      To breed more four-seed pods varieties, construct the ideal model, and explore new ways for highyield breeding and super-high-yield breeding, the physiological and ecological characteristics of‘Fendou 96’ are analyzed by spss18. The variety‘Fendou 96’with elliptic leaves and more four- seed pods and 34 accessions with lanceolate leaves and four-seed pods were used as materials. The ideal model was constructed by stepwise regression method for 10 yield-related agronomic traits. The results showed that plants with fourseed pods were more than 85% in‘Fendou 96’population, and the maximum number of four-seed pods per plant was 49, accounting for 30.25% of the total pods. The yield of‘Fendou 96’increased with the increasing number of four-seed pods. WhenR 2=0.939, the model fitting was the best:Y =-87.583+0.415X 1-5.155X 2 + 10.094X 3+13.459X 4. The regression equation showed that there was a significant linear regression relationship between yield and biomass (X 1), plant height (X 2), 100-grain weight (X 3) and the number of main stem nodes (X 4). To improve the number of grains per pod and breed varieties with more four-seed pods is a new way for high-yield variety breeding. The ideal model of soybean varieties is the short internode dense pod type with lodging resistance, multi-seed pod, and suitable for mechanized harvesting.
