Genetic Divergence Studies in Some Indigenous Scented Rice (Oryza sativa L.) Accessions of Central India

Deepak Naik, Abhinav Sao, A.K. Sarawgi and Pushpendra Singh    

Abstract: The genetic divergence study was conducted to estimate the nature and magnitude of diversity in fifty aromatic rice accessions including five scented improved varieties viz., Pusa Basmati, Taraori Basmati, Indira 9, Dubraj and Madhuri 11 as checks during wet season, 001. The D2 analysis indicated the presence of appreciable amount of genetic diversity in the material. The fifty genotypes were grouped in to seven clusters. The cluster VI had the highest mean for grain yield per plant and for biological yield per plant. Inter cluster distance was recorded highest between cluster 3 and cluster 4. The least distance was recorded in between cluster 1 and cluster 5. The conclusion drawn by the cluster analysis is that in the studied population high variability observed between the genotypes in different clusters for different characters. The genotypes Taraori Basmati, Jaigundhi, Krishnabhog, Samunderphool, Sansari, Amtma Shital, Bhataphool, Ghodapunchi, Tulsimala, Dumerphool, Loktimachii and Elaychi can be used as potential donors for future hybridization programme to develop scented rice variety with good grain yield and quality traits.
