Mean performance and correlation analysisfor yield and yield contributing traits in brinjal (Solanum melongena L.) genotypes

A comparative study on 40 brinjal genotypes for growth, flowering and yield attributing parameters was conducted at Vegetable Experimental Farm, Division of Vegetable Science, SKUAST-Kashmir, Shalimar during kharif season, 2021. Based on mean performancethe earliest flowers were produced in SKAU-B-193 however; earliest fruit were set in SKAU-B-241 and fruits were earliest harvested in SKAU-B-241. SKAU-B-209 recorded maximum number of branches per plant. Maximum plant height was recorded in the SKAU-B-276 and plant spread was maximum in IC-111010. Maximum fruit length was recorded in the genotype SKAU-B-274 while SKAU-B-276 has widest fruits. SKAU-B-226 produced highest number of fruit per plant whereas, SKAU-B-231 recorded highest average fruit weight. The yield per plant, per plot and per hectare was highest in genotype SKAU-B-276. Maximum TSS was recorded in SKAU-B-205 whereas; maximum anthocyanin content was recorded in SKAU-B-225 and maximum ascorbic acid content was estimated in IC-111010. Maximum phenols were recorded in SKAU-B-266. Total sugars were highest present in SKAU-B-234 and highest dry matter was recorded in IC-354867.The correlation coefficients among the different characters were worked out at both genotypic and phenotypic levels. In general, magnitudes of genotypic correlation coefficient were higher than their corresponding phenotypic correlation coefficient, implying a significant inherent relationship in different pair of traits also the economically important trait i.e., fruit yield per hectarewas positively and significantly correlated with fruit yield per plant followed by plant spread, number of fruits per plant, plant height, average fruit weight and fruit length.
