One hundred fifty three exotic whellt genotypes were evalullled alongwith three checks for quantitative characters to study genetic divergence by employing D2 analysis. The genotypes were grouped in to 13 diverse clusters. Clustering plltlern of genotypes showed no definite relationship between genetic divergence and geographical distribution of genotypes. The highest genetic divergence was observed between cluster V and VIII. whereas. cluster I and II were closest one. On the basis of genetic divergence and mean performance. nine diverse and superior genotypes. being exceptionally good for one or more traits and reasonable for other comparison to checks, were selected and these genotypes may be useful in multiple crossing or diallel selective mating system to recover transgressive segregants.
