Abstract:
The present investigation on genetic variability, heritability and correlation study including mean, genotypic and phenotypic variances, coefficient of variation, heritability, and genetic advance was conducted on genetically diverse nineteen genotypes of onion (Allium cepa L.) in the “Rabi Season.” was carried out in the rabi season Research field, Department of Horticulture, Sam Higginbottom Institute of Agriculture, Technology & Sciences, Allahabad during the year 2013-2014. The investigation was laid out in RBD with three replications. There were 7 genotypes wide variation was observed among the genotypes for all traits. Results revealed that the genotype the phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) for all the traits. Performed betterin terms of yield and yield attributing characters and therefore, these lines may be used for breeding programme. Large amount of variability exhibited in the genotypes for selection. Significant differences were observed among the genotypes for all the traits. Similarly, the high heritability and genetic advance were also recorded on Fresh weight of bulb and Dry weight of bulb, being suggesting the major role of genetic constitution in the expression of the characters. Dry weight of bulb had positive and highly significant correlation with yield per ha and Bulb yield per plot both at phenotypic and genotypic level, respectively.
