Abstract
The investigation was conducted at Horticultural Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during the rabi season of 2017-2018.
The experiment was laid out in randomized block design in three replications with seventeen genotypes to estimate the mean performance of those genotypes, genetic variability, heritability, genetic advance, character association, path analysis and to identify best genotype suitable for Chhattisgarh plains among them.
From the mean performance of the brinjal genotypes it was found that 2017/BRLVAR-8 (846.67q/ha) and 2017/BRLVAR-9 (783.21q/ha) were most promising with respect to yield per hectare.
The magnitude of PCV was higher than the concurrent GCV for all the characters. This might be due to the interaction of the genotypes with the environment to some degree or due to environmental factors stimulating the expression of these traits. High heritability coupled with high genetic advance was observed for the characters like number of primary branches per plant, number of flowers per inflorescence, average fruit wt. (g), fruit yield per plant (kg) and fruit yield per hectare (q).
In the analysis of correlation coefficient of all the attributes it was found that plant height, days to 50% flowering, number of cluster per plant, fruit length, first marketable fruit maturity and fruit yield per plant have preponderated effect on fruit yield per hectare (q).
In path coefficient analysis it was found that plant height (cm), number of flowers per cluster, number of primary branches per plant, pedicel length (cm), pericarp thickness (mm), days to first marketable fruit, showed positive and direct effect and had significant positive correlation with fruit yield per hectare (q).
Hence after complete investigation the attributes plant height (cm), number of primary branches per plant, pedicel length (cm), pericarp thickness (mm), fruit length (cm) and number of flowers per cluster, days to first marketable fruit are found to be superior yield component.
