摘要
以58份不同西瓜(Citrullus lanatus)种质为材料,对种子长度、种子宽度、种皮底色、种皮覆纹特征等11个表型性状进行遗传多样性分析,结果表明:西瓜种子千粒质量、种子宽度、种子长度、种子厚度、种喙宽度的变异系数依次为47.9%、28.0%、26.5%、16.0%、16.0%;种皮底色和种喙颜色分别有12种不同类型,其中黄色种子和黑色种喙的种子最多,分别占27.6%和31.0%。种子覆纹特征和种子表面光滑度分别有4种类型,其中灰褐斑点覆纹占20.7%,种子表面粗糙型占58.6%。种子形状和种子表面形状分别有2种和3种类型,以椭圆形和平面种子较多。
Genetic diversity was studied on 11 seed phenotypic traits using 58 accessions from National Mid-term Genebank for Watermelon ＆ Melon. The result showed that the co-efficiency of variation was arranged 47.9 （1 000-seed weight）, 28.0 （Seed width） ,26.5 （Seed length）, 16.0（Seed thickness and hilum width）. There were 12 different types of color of seed and hilum. The yellow seed and black hilum was the most common,accounting for 27.6% and 31.0% respectively. There were four types of secondary color pattern of seed surface and smoothness of seed surface ,20.7% secondary colors were gray- brown spots,58.6% seed surface were coarse. There were two types of seed shape and three types of seed surface,oblong shape and flat seeds were more common.
