| 摘 要： | 运用灰关联分析法对来源不同的33份冬瓜材料的11个产量相关性状进行了灰关联度分析,结果表明:决定产量的关键因素是单瓜重、瓜形指数、瓜长和瓜肉厚;决定单瓜重的关键因素是肉厚、瓜长、横径和病毒病病情指数;抗病性对瓜肉致密性的影响最大。32号自交系的增产潜力最大,19号和13号次之。

Study on Comprehensive Evaluation of Yield Relative Characters of Wax Gourd by Grey Relation Degree Analysis |
| |
| Abstract: | Eleven yield relative characters of thirty-three wax gourd self-cross lines from different regions were analyzed by grey relation degree analysis, the results revealed that the key traits which affected the yield were fruit weight, index of fruit shape, fruit length and thickness of fruit flesh,while thickness of fruit flesh, fruit length,fruit width and index of virus disease were the main traits which affected the fruit weight,the disease resistance had the greatest influence on the compactness of fruit flesh.Among 33 wax gourd cultivars, No.32 had the greatest yield potential,No.19 and No.13 followed next. |
