通过对适龄蒜苗进行种瓣重量，假茎长度、假茎粗度、叶数、单株干重、单株鲜重及根数等７个性状的相关和通径分析。结果表明：大蒜蒜苗各性状间有密切的相关性，各因素对产量的相关系数及通径系数具有明显差异，其相关系数大小依次为：单株干重（０．９６６９）、假茎粗度（０．９６２３）、根数（０．７９５６）、假茎长度（０．７５５６）、叶数（０．７３６６）和种瓣重量（０．４７１１），相关程度除种辩重量为显著外，其余均达到极显著水平。通径系数大小依次为：单株干重（０．５１３９），假茎粗度（０．３６２１），假茎长度（０．１１５２），根数（０．０３８５）．叶数（０．０３４４），种瓣重量（－０．０４７８）。且单株干重，假茎粗度，假茎长度，根数，叶数对产量有直接的正向作用。
Through the correlation analysis and path analysis of seven traits, such as seed weight, pseudostem length, pseudostem thickness, leaf number, dry weight per plant, fresh weight per plant and root number, The results showed that there was a close correlation between all the characters of garlic allium, the correlation coefficient and path coefficient of each factor had obvious difference, the correlation coefficients were as follows: the dry weight per plant (0.9669), the thickness of pseudostem (0.9623), root number (0.7956), length of pseudostem (0.7556), number of leaves (0.7366) and seed weight (0.4711) The rest reached a significant level. The order of path coefficient is as follows: dry weight per plant (0.5139), pseudostem coarseness (0.3621), pseudostem length (0.1152), root number (0.0385). Leaf number (0.0344), species weight (-0.0478). The dry weight per plant, pseudostem thickness, pseudostem length, root number and leaf number had a direct positive effect on the yield.
