CLUSTER ANALYSIS FOR DIFFERENT GENOTYPES OF PEANUT

Abstract

ABSTRACT:A field experiment was carried out at four sites (Al-Anbar ,Al-AshaqiGaloulaa andAl-Kut ) in 2002 to test the performance of 11 genotypes of peanuts (ArachisHypogaea) and accumulated into uniform groups, in addition to estimate the genetic diversity in term of euclidean distancethrough cluster analysis. Pod yield was analyzed based on hierarchical clustering technique after constitute resemblance matrix. The genotypes grouped into six clusters which they formed during teen stages. Each group consisted of two genotypes beyond groupVI which it consisted of one group. The cluster analysis indicated that genotypes Medni and ICGV863 were hadsimilar response because of having minimum Euclidean distance and this may be an indicator of similarity for the genes they carry on. The genotype C92 had the highest Euclidean distance and genetic diversity and this may be a result of difference of its pedigree. The tested genotypes were grouped into two major groups, group (A) included genotypes I, III , VI,while group B included the rest genotypes which had highest yield than A, this may be a result of existing favorable genes govern yield character. The local cultivars can be improved through transporting the yield genes from diverse, superior genotypes.
