Abstract:

The seed material of 18 genotypes of Brassica napus L. was procured from different institutes. In order to check the authenticity of the work four other genotypes of different Brassica species were also used. Genetic diversity of these genotypes was assessed using morphological traits. The characters days to maturity, plant height, number of primary branches/plant, number of seeds/siliqua, number of siliqua/plant and seed yield /plant showed higher influence of environment whereas, siliqua length and 1000-seed weight showed the least. Days to maturity and days to 50% flowering exhibited the highest heritability. The significant positive correlation with seed yield/plant was found in plant height, number of primary branches/plant, number of siliqua on main raceme, 1000-seed weight, oil content, days to 50% flowering and days to maturity. Path coefficient analysis showed that the plant height had maximum positive direct effect on seed yield followed by 1000-seed weight and siliqua length. Plant height, number of primary branches/plant and number of siliqua on main raceme were the most important contributors to seed yield/plant which could be taken consideration in future selection program. Significant genetic variability was obtained among the selected 22 genotypes through dendogram analysis the genoypes viz. AKGS-3, EC552608 were more diverse from the rest of the Brassica napus L. sps. So, the genotypes AKGS-3 and EC55208 should be used to exploit heterosis in hybridization programme with the other Brassica napus genotypes considered in the study.
