Abstract
The present investigation entitled “Genetic variability and correlation studies in dill (Anethum graveolens L.)” was carried out with seventeen genotypes including one check. The genotypes were sown in Randomized Block Design with three replications, during rabi 2018-2019 at Chilli and Vegetable Research Unit (CVRU), Dr. PDKV, Akola.
The observations were recorded on five randomly selected plants for fourteen characters viz., plant height, number of branches, number of umbels per plant, number of umbellate per umbel, seed yield per plant, number of seeds per umbel, number of seeds per umbellate, test weight, oil content, days to 1st flowering, days to 50% flowering, days to maturity, germination percentage and seed yield per plot. The data so obtained was subjected to analysis of variance, estimation of different variability parameters, genetic correlation coefficient analysis and path analysis.
Analysis of variance revealed significant values of genotypic mean sum of square, for all the fourteen characters under study. The characters, number of seeds per umbel, number of umbels per plant, days to first flowering, plant height at maturity and days to 50% flowering exhibited higher magnitude for genotypic mean sum of square.
High GCV coupled with high heritability and expected genetic advance of a character provides good selection advantage. Therefore, there is substantial scope for improvement of seed yield per plant, number of umbels per plant, test weight, number of seeds per umbel and number of seeds per umbellate. Selection for these characters would be effective in selection for suitable genotype of dill improvement programme in future.
Association study indicated that, seed yield per plot was positively and significantly correlated at genotypic level with number of branches per plant, numbers of umbels per plant, number of umbellets per umbel, seed yield per plant, number of seeds per umbel and number of seeds per umbellate. This association indicated that, improvement in seed yield can be achieved by improving the above characters.
Based on direct and indirect effects of different yield components on seed yield, it appears that, more stress on plant height, number of branches per plant, number of umbel per plant, number of umbellets per umbel, number of seeds per umbel, number of seeds per umbellet and germination percentage will be useful in identifying the dill genotypes as parents for further improvement.
Therefore, on the basis of yield and yield contributing characters, the genotypes AKDIL-02, AKDIL-04, AKDIL-05 and AKDIL-13 could be undertaken in future improvement programme.
