对韭菜 4 9个品种或杂交组合构成单株产量的 6个主要性状进行相关及通径分析 ,结果表明 ,韭菜单株产量与鞘粗、叶长、株高、叶片数呈极显著正相关 ,与叶宽呈显著正相关 ;株高对单株产量的直接效应最大 ,鞘粗次之。株高、叶长、鞘粗对单株产量的直接决定系数最大 ,是影响单株产量的主要因素 ,可作为韭菜高产高效育种的主要选择性状。 The correlation analysis and path analysis of 6 main characters of 49 cultivars or hybrid combinations of Chinese chives showed that there was a significant positive correlation between individual plant yield and sheath thickness, leaf length, plant height and leaf number, And leaf width was significantly positive correlation; plant height on the yield of the largest direct effect, followed by the sheath thickness. The direct determination coefficient of plant height, leaf length and sheath thickness on the yield per plant was the largest, which was the main factor affecting the yield per plant and could be used as the main selection traits for high yield and high efficiency breeding of Chinese chives.
