摘要

采用3个重复的随机区组设计对30个卡布力鹰嘴豆基因型进行评价。性状关联分析表明,单株次枝数、单株荚果数、单株梢生物量和收获指数与单株种子产量呈极显著正相关。通径分析还表明,收获指数和地上部生物量对单株种子产量有较大的直接影响。因此,通过收获指数和地上部生物量的选择来提高种子产量更为有效。

Character Association and Path Coefficient Analysis in Extra Large and Large Seeded Kabuli Chickpea (Cicer arietinum L.)
Thirty kabuli chickpea genotypes were evaluated in a randomized block design with three replications. Character association analysis revealed that number of secondary branches per plant, number of pods per plant shoot biomass per plant and harvest index showed highly significant and positive correlation with seed yield per plant. Path analysis also revealed that among correlated traits, harvest index and shoot biomass exerted high direct effect on seed yield per plant. Hence, selection would be more effective through harvest index and shoot biomass to improve seed yield.
