| 摘 要： | 为发掘和利用西瓜优异的种质资源,本研究对100份西瓜的主要果实性状进行了分析。结果表明:果实平均重和千粒重变异系数较大,果皮硬度和含糖量变异较小。基于果实性状的聚类分析将供试材料分为4个类群。类群I,包括21份材料,主要来自美国和日本,美国的材料占该类群的42.9%,日本材料占38.10%,该类群的特点是果实中等、种子小、含糖量高、硬度高;类群Ⅱ,包括25份材料,16份来自国内,占该类群的64%,其特点为果实大、种子大、含糖量中等、硬度高;类群Ⅲ,包括35份材料,主要来自日本,占该类群的54.28%,该类群特点是果实中等、种子小、含糖量高、硬度差;类群Ⅳ,包括19份材料,主要来自美国的PI系列,占该类群的63%,其特点为果实小、种子中等、含糖量低、硬度中等。

| Abstract: | In order to make use of excellent germplasm of watermelon,the main fruit traits of 100 watermelon materials from different regions were analyzed.Results showed that variations of average weight of fruit and 1 000-seed weight were of higher level,whereas lower variations in peel hardness and sugar content.Through cluster analysis,the materials were classified into 4 groups(Gs) when the threshold was 10.GI,21 varieties including 9 from USA(42.9%) and 8 from Japan(38.10%) respectively,was moderate fruit-little seed-low sugar content-high peel hardness;GII,25 materials,16 from China(64%),was large fruit-big seed-moderate sugar content-high peel hardness;GIII,35 varieties,54.28% of which came from Japan,was moderate fruit-little seed-high sugar content-low peel hardness;GIV,19 varieties,mainly from USA(63%),was small fruit-moderate seed-low sugar content-moderate peel hardness. |
