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。
An analysis of variance was made on 11 major agronomic traits of 9 introduced elite soybean varieties. Correlation analysis was made on 15 major agronomic traits. The results showed that: (1) The stem diameter and grain weight of main agronomic traits were analyzed by analysis of variance Significant levels of plant height, height of pod, height of main pods, number of main stems, number of main stems, total pods of pods, number of pods per pod, number of pods per pod and weight of one hundred seeds reached the most significant level by ANOVA. (2) The variation coefficient of the main agronomic traits were as follows: pod number, branch number of main stem, pods per plant, grain number per plant, yield per plant, height of pod, number of pods per pod, Height, stem diameter, yield, number of main stems, emergence to flowering, flowering to maturity and growth period; (3) There was a significant positive correlation between yield and growth period and pod number, The number of shoots per plant, the number of per plant, the number of kernels per 100 grains and the number of flowering to mature days were positively correlated with the number of stems, the number of main stems, the number of pods per plant, the number of grains per plant and the days from emergence to flowering Related. Therefore, to increase production, first of all should consider a hundred varieties of large, single plant productivity potential varieties, followed by considering the lower pod height, pods per pod number of varieties.
