摘要
对29个头蒜品种的13个农艺性状进行评价,并对其中12个农艺性状与单株产量进行相关与通径分析。相关分析表明,蒜头横径、蒜头高、叶宽、叶长、株高、外瓣数与单株产量的相关性达极显著水平,相关系数分别为0.95、0.92、0.84、0.71、0.61和0.47。通径分析表明,蒜头横径、蒜头高、叶宽与叶长4个性状对单株产量的影响较大。结合回归方程,确定蒜头横径、蒜头高与叶宽为影响单株产量的主要因素,可以作为大蒜高产育种的重要指标。
The correlation and path analysis of 13 agronomic characters in 29 garlic cuhivars were studied, and the agronomic characters were evaluated as well. The results indicated that the correlation reached significant level （ P 〈 0.01 ） between yield per plant and garlic bulb transverse diameter, garlic bulb height, leaf width, leaf length, plant height and the number of outer layer garlic cloves, the correlation coefficients were 0.95, 0.92, 0.84, 0.71,0.61 and 0.47 respectively. According to the results of correlation analysis, path analysis and regressive equation, the yield per plant was affected largely by garlic bulb transverse diameter, garlic bulb height and leaf width. Therefore, these three characters could be taken as the important indexes for the high - yielding breeding of garlic.
