Abstract
The present investigation was carried out at Vegetable Research Station, Junagadh Agricultural University, Junagadh during late Kharif/Rabi 2018- 19 in Randomized Block Design with three replications. The experiment was conducted to assess genetic variability, character association and path coefficient analysis in brinjal. The experimental material comprised of thirty five genotypes and 5 check varieties. The characters studied were days to 50% flowering, days to first picking, days to last picking, number of pickings, fruit length (cm), fruit girth (cm), fruit weight (g), number of fruits per plant, number of branches per plant, plant height (cm), plant spread (cm), total fruit yield per plant (kg), total soluble solids (B◦) and fruit borer infestation (%).
The analysis of variance revealed that mean sum of square due to genotype was highly significant for all fourteen characters studied. High phenotypic and genotypic coefficient of variation, high heritability coupled with high genetic advance as per cent of mean were observed for fruit borer infestation, number of fruits per plant, fruit weight, fruit length, number of branches per plant, plant height and total fruit yield per plant.
Total fruit yield per plant has recorded positive and significant correlations with days to last picking, plant height, number of fruits per plant, fruit length and plant spread.
Path coefficient analysis revealed that number of fruits per plant and fruit weight had high and positive direct effects on fruit yield per plant.
On the basis of all the above studies, it can be concluded that due weightage should be given to number of fruits per plant and fruit weight while imposing selection for genetic improvement in brinjal.
