余甘子育种资源分类与评价

通过对余甘子20个指标30个品种的分析表明：来自不同地方的品种具有一定的区域性，同一区域的品种大体在同一类，全部参试品种分成了两类即G1类和G2类，其中G1全是来自印度的品种，G2类是国内不同分布区的品种和育种材料。2大类相应分为5个亚类。G1类开花结实性状主要表现在大果．雌花比例高．结果枝丛生性和结果枝结果数极少。G2类开花结实性状表现为结果枝和果实丛生性强，雄花比例低等优良性状，但果实大小普遍偏小。来自印度的品种和国内的品种材料间在开花结实生物学特性上具有较强的互补性。为以后的杂交育种提供了资源。

Classification and evaluation of Phyllanthus emblica Breeding Resources

The analysis 20 index of blossom and fructification of 30 varieties of Phyllanthus emblica indicates: the 30 varieties divided into two groups viz group one (G1) and group two (G2). Group one consists of varieties and clones introduced from foreign countries, and group two is the breed and the breeding material from internal different distributions in China. Two big groups are correspondingly divided into 5 inferior kinds. The group one's chiefly properties are bigger fruit, higher proportion of female flower, extremely few of fructicative branch number. The group two's chiefly properties are small fruit, lower proportion of male flower, more of fructicative branch growing thickly nature and the fructicative number. So the properties of blossom and fructification of Phyllanthus emblica from India and China have strong complementary which provided the resources for the later crossbreeding research projects.
