哈尼梯田社区种质库水稻种质资源表型多样性研究
|
摘要
为保护哈尼梯田水稻(Oryza sativa L.)资源,在国际农业发展基金资助下,广泛收集哈尼梯田水稻资源并帮助当地农民建立社区水稻种质库,对种质库保存的72份水稻种质资源表型性状进行了测定分析,并基于表型性状数据进行聚类分析以揭示它们之间的亲缘关系。结果表明,供试水稻种质资源株高、茎秆直径、有效穗、第一剑叶长宽比变异较大,穗长、结实率、谷粒性状和千粒重变异较小。通过聚类分析,当欧式距离为11时,72份材料可聚为4个组群,各组群性状差异明显。
In order to protect rice(Oryza sativa L.) resources, varieties were collected and a community seedbank was built depending on the international fund for agricultural development funding. Morphological traits and cluster analysis of 72 varieties from Hani community seedbank were conducted. The results showed that there was a high level variation in plant height, stem diameter, number of spikes, flag leaf size, but low level variation in spike length, kernel set, kernel size and1 000-grain weight. 72 varieties were classified into 4 groups at 11 Euclidean distances, and each group had obvious features.
