| 摘 要： | 以21个大葱品种为试材,对10个农艺性状进行了相关分析、通径分析与回归分析。相关分析表明:株高、葱白长、葱白直径、叶长、叶扁宽、绿叶数、叶鞘间距等性状均与单株重呈极显著正相关。通径分析和回归分析结果表明:葱白长、葱白直径、叶扁宽、绿叶数是影响单株重的主要因素。

Correlation and path analysis of some agronomic character of welsh- onion |
| |
| Abstract: | Correlation analysis and path analysis were carried out in 21welsh-onion cultivars of 10 agronomic characters. The result of correlation analysis revealed that stem length, welsh-onion stalk length, welsh-onion stalk width, leaf length, leaf width, leaf numbers, distance of the adjacent leafs were related to the yield of plant positively. The results of path analysis indicated that welsh-onion stalk length, welsh-onion stalk width, leaf width, leaf numbes were important factors for the yield of the plant. |
