Cluster Analysis of Red Rice based on SSR Markers from Hani's Terraced Fields in Yunnan Province

摘要

Genetic diversity is the main source of variability in any crop improvement program. There are abundant rice landraces in Hani's terraces fields in Yunnan, especially red rice resources. A set of 61 red rice landraces were characterized using 78 simple sequence repeat (SSR) markers. Cluster analysis based on unweighted pair group method with arithmetic mean showed that the similarity coefficients varied from 0.19 to 0.85, all genotypes grouped into two major clusters in the dendrogram at 0.19 similarity. Indica rice clusters including 58 rice landraces as main rice cultivation types in Hani's terraces fields in Yunnan.
