Abstract

                                Thirty two genotypes of barley were collected from different centres of Indi including some exotic strains. These were planted in rainfed condition and clustering of genotypes was done by means of Mahalanobis' D2 analysis and Anderson's metroglyph clustering. In the first case the cultures grouped themselves into 6 clusters. No relation was found between geographical and genetic diversity. From the per se performance, intercluster distance and cluster composition, it was inferred that Karan-15 may be crossed with LHDP-238, (a), Karan-19 (b), Karan-521 (c), BCB (Hyl)-7 (d). Karan-201 (e) LLK-224 (f), or BON (MRA)-13 (8) for overall yield improvement on the basis of D-analysis. In case of metroglyph analysis, the genotypes were grouped into 7 clusters. The prospective cross on the basis of later one predicted, such as 'a', 'd', 'e', ' and 'g' were common for both analysis. Therefore, it can be concluded that Anderson's metroglyph analysis although not comparable to D-analysis, could be a meaningful support to D and in the absence of systematic clustering, could be a good indicator at field level.
