摘要
通过对在碳酸盐草甸土上种植的9个大豆抗线品种(系)主要性状关联度的计算及关联序的排列,研究了在此种土壤上影响大豆抗线品种(系)产量的主要因素。结果表明,单株粒重在大豆抗线品种(系)中对产量的作用居所有性状之首,其次是株高>有效荚数>单株粒数;产量与主要性状的关联度大小依次为单株粒重>株高>有效荚数>单株粒数>生育日数>主茎节数>百粒重>脂肪含量>蛋白含量;因此在碳酸盐草甸土上进行大豆抗线品种种植时可以选用多荚型(或多粒型)品种,提高品种的产量潜力。
Through computation of correlation degree and arrangement of correlation order with nine SCN resistant cultivars (lines) of main traits in carbonate meadow soil, it researched the principal element which interfered with yields of SCN resistant cultivars (lines) in this soil. The results showed that the correlation order between agronomic traits and yield was as follows: seed weight per plant 〉 plant height〉effective pod number〉seed number per plant〉number of growing days〉main stem node number〉100-seed weight〉fat content〉protein content. So in order to increase production, the more pods (seeds) of SCN resistant cultivars (lines) should adapt to grow in carbonate meadow soil.
