| 摘 要： | 调查了印度 25 个不同农业气候条件下的桑树(Morus spp.)基因型的 14 个形态测量性状, 以研究它们的遗传多样性分布特点。研究发现在 14 个性状中存在广泛的遗传变异。25 个不同基因型的桑树被分为 10 个簇。实验结果表明 7 种基因型桑树 Baragura-2, Gorabandha-2, Kalimpong, Herbertpur, Kollegal, Resham majri-7 和 UP-14 的遗传资源是重要的。对不同基因型桑树性状的关联分析显示, 对桑树叶片长度、新鲜叶的总量、叶片面积和单个叶的重量这些性状的直接筛选将有助于提高桑树叶片的产量。

| Abstract: | Fourteen morphometric traits were used to examine the genetic divergence of 25 mulberry (Morus spp.) genotypes from varied agroclimatic conditions of India. Wide variation was observed for all the traits. The genotypes irrespective of their place of collection were grouped into 10 different clusters. Seven accessions, that is, Baragura-2, Gorabandha-2, Kalimpong, Herbertpur, Kollegal, Resham majri-7, and UP-14 each a cluster of unique entries will be of useful for genetic resources. Nevertheless, the cor-relation and path analysis suggest the direct selection of lamina length, fresh leaf weight, leaf area, and single leaf weight will be rewarding for mulberry leaf yield improvement. |
