对195份水稻材料进行了基因型多样性分析。基因型分为10个聚类。结果表明，基因型最多（28个），其次为基因型最多（27个）。聚类间距离大于聚类内距离，表明基因型间存在较大的遗传多样性。聚类VI和聚类VII的群间距离最大，其次是聚类IV和聚类VII的群间差异较大。聚类I的簇内距离最大，其次是聚类IX。具有IC的材料346231、352813、346237、331640、152036、372020可以作为潜在的供体进行杂交计划，以培育具有更高产量潜力的品种。
One hundred and ninety five rice accessions were evaluated to study the diversity pattern among the genotypes. The genotypes were grouped under ten clusters. The distribution pattern indicated that maximum number of genotypes (28) were grouped into cluster II, followed by 27 in cluster III. The inter-cluster distance is higher than intra cluster indicating wide genetic diversity among the genotypes. The highest inter-cluster distances was observed between cluster VI and VII followed by cluster IV and VII showed wider diversity among the groups. The highest intra-cluster, distance was observed for cluster I followed by cluster IX. The accessions with IC 346231, 352813, 346237, 331640, 152036, 372020 can be used as potential donors for hybridization programme to develop variety with higher yield potential.
