The present investigation was comprised of 30 lines of rice Germplasm along with three checks viz., Narendra Usar 3, Sarjoo 52 and IR 28. The material, comprising indigenous as well as exotic germplasm lines, exhibited wide spectrum of variation for various agronomic and morphological characters. In the study, genetic divergence among 33 genotypes of rice under sodic soil was performed by employingD2 statistics and Non-hierarchical Euclidean cluster analysis as described by Beale (1969) and Spark (1973). The 33 genotypes were grouped into 6 different non-overlapping clusters. Cluster II, containing 11 genotypes, emerged with highest number of genotypes, while cluster III with 6 genotypes contained second highest number of entries among 6 clusters. Cluster I was represented by 5 genotypes. Cluster IV and cluster V also possessed 5 entries each. Cluster VI with one genotype had lowest number of entries. The discrimination of lines into so many discrete clusters suggested presence of high degree of genetic diversity in the material evaluated. Presence of substantial genetic diversity among the lines screened in the present study indicated that this material may serve as good source for selecting the diverse parents for hybridization programme aimed as isolating desirable segregates for developing high yielding varieties of rice suitable for sodic soil.
