Genetic Diversity Analysis by D2 Analysis in Fine Scented Genotypes of Rice (Oryza sativa L.)

The present investigation on “Diversity analysis by D2 analysis in fine scented genotypes of rice (Oryza sativa L.)” was used to investigate the diversity among 40 fine scented genotypes obtained from the Indira Gandhi Krishi Vishwavidyalaya in Raipur. The current studies was conducted at research cum instructional farm, IGKV, RMD Ambikapur, Chhattisgarh. The experiment was conducted in RBD with purpose to characterized 40 genotypes of rice along with 4 checks viz. CG Sugandhitbhog, CG Devbhog, Indira Sugandhit Dhan-1 and Dubrajsel 1 for diversity. Based on cluster analysis, the genotypes were grouped into 5 clusters in which cluster I was the largest consistin of 29 genotypes. While cluster IV & V were the smallest with only a single genotypes; each. Maximum intra cluster distance was found in the cluster II, Which comprises only 5 genotypes. The most divergent clusters observed were cluster III & V. The minimum cluster distance was recorded between cluster I & III.
