Genetic Components and Diversity Analysis in Indian Mustard [Brassica juncea (Linn.) Czern & Coss] Based on Different Morpho-physiological Traits

Aim: Indian mustard [Brassica juncea (Linn.)] is the third vital oilseed crop in world which contributes 28.6% production of oilseeds. Genetic diversity assessment plays a fundamental role preservation and improvement targeted plant species.
 Study Design: In present investigation, 196 genotypes including checks were grown field evaluated based on different morpho-physiological traits.
 Place Duration Study: All randomized block design with two replications Rabi 2016-17 2017-18 at experimental Department Genetics & Plant Breeding, College Agriculture, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior, M.P., India.
 Methodology: The study was conducted to record morphological physiological traits that play major differentiating genotypes.
 Results: Based study, highest genotypic phenotypic coefficients disparity documented for seed yield per tracked by harvest index numbers silique plant. Maximum heritability genetic advance plot index, biological plot, days 50% flowering, length main raceme, plant, seeds silique, 1000-seed weight raceme.
 Conclusions: principal component analysis, 15 components evidenced while cluster analysis gave 16 clusters. inter-cluster distance between 9 suggests hybridization scheme considering parents from these clusters supposed be given higher occurrence better-wanted combination(s) expansion beneficial stocks.
