| 摘 要： | 对119西瓜种质材料果实性状的变异性进行了研究。结果表明:119份西瓜种质材料的果实形状、皮色、瓤色等质量性状几乎涵盖了西瓜的所有类型。果实单果重、果皮厚、含糖量等数量性状变异范围也较大,极差分别为5.5kg、1.7cm和8.1%,其中单果重变异系数最高,为62.0%,其次为果皮厚,变异系数为31.4%,含糖量变异系数为20.0%。根据单果重、果皮厚度和含糖量,采用系统聚类法,将119份西瓜种质材料分成10类。为这些种质资源的进一步利用和创新提供了参考和依据。

| Abstract: | Variability of fruit characters of 119watermelon germplasm materials was studied.The results showed that the 119watermelon germplasm materials included almost all kinds of watermelon in fruit ship,pericarp color and flesh color.The variability of single fruit weight,pericarp thickness and sugar content was also large with range of 5.5kg,1.7 cm and 8.1%respectively.Single fruit weight showed the highest coefficient of variance of 62.0%followed by pericarp thickness and sugar content with coefficient of varia... |
