Genetic divergence in linseed (Linum usitatissimum L.).

Begum, H., Alam, A. K. M. M., Chowdhury, M. J. A. and Hossain, M. I. 2007. Genetic Divergence in Linseed (Linum usitatissimum L.). Int. J. Sustain. Crop Prod. 2(1): 04-06. The D analysis allowed the 36 genotypes/variety of linseed to be identified into five distinct clusters. The cluster I included 11 genotypes that had medium mean values for 1000-seed weight (g) and seed yield/plant. The cluster II contained 6 genotypes, which had the highest mean values for number of seeds/capsule, number of branches/plant and seed yield/plant. They also showed the highest mean value for plant height. The cluster III had maximum number of genotypes 15, which had the highest mean value for 1000-seed weight (g). It is also related with medium mean values for rest of the characters. The cluster IV included 3 genotypes having the highest mean values for number of capsules/plant and days to maturity. The cluster V included single genotype, which had the lowest mean values for days to maturity and plant height. The highest intercluster distance was observed among clusters V, IV and II, while the lowest between III and I. The highest intracluster distance was observed in cluster III that revealed maximum variability within the clusters. In this study, two traits such as number of branches/plant and number of seeds/capsule contributed the maximum towards divergence in the existing germplasm.
