      abstract = {Genetic diversity is essential to meet the diversified  goals of plant breeding such as producing cultivars  with
increased yield, wider adaptation, desirable quality,  pest and disease resistance. In this study genetic  diversity and
selection index of 24 genotypes of bread  wheat were evaluated. The performance of 24 wheat genotypes  showed
that there were significant variations for the  characters suggesting the presence of genetic variability  among the
genotypes. The genotypes were grouped into five  clusters viz. I, II, III, IV and V based on Mahalanobis’ D2  statistics.
Cluster I and II were the largest group  containing six genotypes and the rest three clusters  contained four, five and
three genotypes respectively. The  genotyps belonging to the same group had smaller D2- value  than between those
belonging to different clusters. Study  on selection indices through discriminate function showed  that Anza ranked as
the best followed by the genotypes  Rawal, PBW-373 and Kheri and suggests that these highest  scoring genotypes
might be recommended for farmers’  cultivation for better yield and it would be expected  genetic gain upto 49.77%
through selection practices based  on the characters studied. Therefore, a crossing programme  could be made among
the genotypes belonging in cluster I  and cluster V will provide maximum heterotic combination,  especially for yield of
bread wheat. Alternatively, among  the studied genotypes Anza could be cultivated for better  performance.},
