Abstract

For assessing the variability among thirty brinjal genotypes the present investigation was carried out at Horticulture complex, Department of Horticulture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (M.P.). Wide variability was recorded among the thirty genotypes studied. The PCV was higher than the GCV for almost all the characters. Both the PCV and GCV were high for traits LAI, the number of long-styled flowers, Number of short-styled flowers, Number of fruits per plant, Girth of fruit, Seed weight per fruit, Pulp: seed ratio, and total phenol content. High heritability accompanied by high GA or GA as % of mean was noted for characters LAI, and seed weight per fruit, indicating the involvement of additive gene action. Direct selection therefore could be effective for the improvement of these traits. The genotypes found superior for most economic traits were 2017/BRLVAR-7, 2017/BRRVAR-10, 2017/BRLVAR-9, 2017/BRRVAR-4, 2016/BRLVAR-5, JB 64, 2017/BRRVAR- 9 and 2016/7BRLVAR-8. Th

Conclusion

The investigation declared significant variation and genotypes found superior for most of the economic traits were 2017/BRLVAR-7, 2017/BRRVAR-10, 2017/BRLVAR-9, 2017/BRRVAR-4, 2016/BRLVAR-5, JB 64, 2017/BRRVAR- 9 and 2016/7BRLVAR-8. These genotypes could be utilized in future hybridization breeding programs. Both GCV and PCV were high for traits LAI, the number of long-styled flowers, Number of short-styled flowers, Number of fruits per plant, Girth of fruit, Seed weight per fruit, Pulp: seed ratio, and total phenol content. The selections on basis of these traits have scope for selections and improvement of traits, while the lowest variability depicted the need for generation of variability. The traits days to 50 percent flowering, Leaf Area index, and Seed weight per fruit reported major heritable portion and thus guide plant breeder in adopting appropriate breeding procedure.
