Genetic diversity analysis of indian mustard (Brassica juncea l.) with respect to its seed traits37138https://krishikosh.egranth.ac.in/handle/1/5810202009Present study entitled, “Genetic Diversity Analysis of Indian Mustard (Brassica junceaL.) with respect to its seed traits” was carried out in the field of PBG, of SKUAST-Jammuduring Rabi season 2022-23. The investigation was carried out with an aim to discriminate the mustard genotypes using seed and plant characters and to determine the genetic diversity among Brassica genotypes.The experiment was sown on plot size of 7.2m2 using Randomised Complete Block Design with 3 replications. Each treatment was sown in rows with length of 4m. The ANOVA for all the different characters showed significant differences at 5% level of significance for all the 12 traits. This suggests that genetic variability is present in all the genotypes.The results based on the seed colours revealed that out of 25 genotypes maximum frequency is gained by black colour having 12 genotypes. Estimates of genetic parametersshowed that highest GCV and PCV data was recorded for all the 12 traits. This further certified that significant amount of variability is present in the traits.Mahalanobis' D2statistics revealed the genetic divergence of 25 genotypes where all genotypes were grouped into 6 clusters, the maximum number ofgenotypes were found in cluster one and cluster second with 16 and 5 genotypes respectively, The maximum intra cluster distance was found between cluster 2(68.4) followed by cluster 1(46.55), while the cluster 3, 4 5, and 6 having one genotype with cluster distance zero. Hence, this proofs that direct selection would be effective and these genotypes can be further used for hybridization program to create strains with high yields.EnglishThesis
