Abstract

A total of 454 rice accessions which resistant to different rice brown planthopper biotypes and rice gall midge China type IV were used for evaluating ten main agronomic traits. The groups were divided according to grade of resistance. W ard cluster analysis method was applied to cluster accessions within each group.One accession per cluster was selected randomly to form core collection. Core collection was composed of 53 accessions. Representational tests showed that core collection covered genetic diversity of the whole collection by comparison of 6 values including Max, Min, Range, Mean, SD, CV, index of diversity (D) of ten characters analyzed.
