【摘要】 对引进的9份大豆优良种的11个主要农艺性状进行方差分析,对15个主要农艺性状进行相关分析,研究结果表明:(1)主要农艺性状中的茎粗、单株粒重经方差分析达显著水平,株高、底荚高度、主茎节数、主茎分枝数、单株总荚数、秕荚数、每荚粒数、百粒重等性状经方差分析达极显著水平;(2)主要农艺性状的变异系数大小依次为秕荚数、主茎分枝数、单株荚数、单株粒数、单株产量、底荚高度、每荚粒数、百粒重、株高、茎粗、产量、主茎节数、出苗至开花、开花至成熟、生育期;(3)产量与生育期、秕荚数呈显著正相关,与株高、底荚高度、主茎分枝数、单株产量、每荚粒数、百粒重、开花至成熟的天数呈正相关,与茎粗、主茎节数、单株荚数、单株粒数、出苗至开花的天数呈负相关。因此,要增加产量,首先应考虑百粒重大、单株生产力潜力大的品种,其次考虑底荚高度较低,每荚粒数较多的品种。更多还原

【Abstract】 Equation Difference analysis for 11 major agricultural characters of 9 imported soybean varieties,and related analysis of their 15 characters.Research shows:1.through equation difference analysis stem width and total grain weight per plant is noted markedly,while plant height,the bottom pod height,knot amount of main stem,branch amount from the main stem,pod amount per plant,blighted pod amount,grain amount per pod,one hundred grain weight,and yield are extremely obvious.2.Beta coefficients(from large to small)are blighted pod amount,branch amount of the main stem, pod amount per plant,grain amount per plant,yield per plant,bottom pod height,grain amount per pod,one hundred grain weight,plant height,stem width,yield,knot amount of main stem,seedling to flowering,flowering to maturity and bearing. 3.Yield is correlated,obviously and positively,with bearing time and blighted pod amount,and,positively,with plant height,bottom pod height,branch amount from main stem,per plant yield,grain amount per pod,one hundred grain weight and days from flowering to maturity,and,negatively,with stem width,knot amount of main stem,pod amount per plant, grain amount per plant,and days from seedling to flowering.In this case,first consideration should be given to varieties with potentials of one hundred grain weight and per plant yield increase,and the second choice should be the varieties of low bottom pod and larger amount of grains per pod.更多还原
