对引自非洲博茨瓦纳（Ｂｏｔｓｗａｎａ）的１６份西瓜野生资源的有关化学成分进行了分析，同时对它们与栽培西瓜的亲缘关系作了探讨。结果表明，这批西瓜资源的种子脂肪主要由４种脂肪酸组成，即棕榈酸、硬脂酸、油酸和亚油酸，其中饱和脂肪酸约占２０％．不饱和脂肪酸约占８０％，两种不饱和脂肪酸含量呈高度负相关；这些资源的果皮中果胶物质含量高出栽培品种２—３倍，具有经济利用价值；亲缘关系分析发现，这批资源大部分属于卡费尔西瓜［Ｃ．Ｌａｎａｔｕｓｓｓｐ．ｌａｎａｔｕｓｖａｒ．ｃａｆｆｅｒ（Ｓｃｈｒａｄ）Ｍａｎｓｆ．］，与目前栽培西瓜属于同一种不同的变种，它们的许多珍贵性状对我国栽培西瓜（包括籽瓜）的品种改良将具有重要的利用价值。
The chemical constituents of 16 wild watermelon resources from Botswana in Africa were analyzed, and their genetic relationship with cultivated watermelon was also discussed. The results showed that the seed fat of these watermelon resources mainly composed of four kinds of fatty acids, namely palmitic acid, stearic acid, oleic acid and linoleic acid, of which about 20% of saturated fatty acids. Unsaturated fatty acids accounted for about 80% of the two unsaturated fatty acids were highly negative correlation; these resources in the pericarp pectin content of cultivars 2-3 times higher, with economic value; genetic relationship found that these resources Mostly belong to Cardiff Watermelon [C. Lanatusssp. lanatusvar. caffer (Schrad) Mansf. ], And the current cultivated watermelon belong to the same kind of different varieties, many of their precious traits for our cultivation of watermelon (including watermelon) varieties will have an important value.
