| 摘 要： | 以55份叶用莴苣种质资源为材料,对其主要数量性状和质量性状及相关性进行分析研究。结果表明,变异系数的分布范围很广,在8.82%~98.85%之间。散叶莴苣的单株重和莲座叶数、最大叶宽呈极显著正相关;结球莴苣的商品球率和最大叶长、最大叶宽、球重呈极显著正相关,但是和株高、莲座叶数呈极显著负相关。 |
| 关 键 词： | 叶用莴苣 遗传多样性 |

| Abstract: | Genetic diversity of 55 lettuce germplasm were analyzed.The results showed that the range of variation coefficient from 8.82% to 98.85%.There were significant positive correlation between plant weight and number of rosette leaves.The plant weight had significant correlation to rosette leaf width(leaf lettuce).The correlations among heading rate and rosette leaf length,rosette leaf width,head weight,and plant height were all positive and highly significant,while heading rate had a negative significant relati... |
