Studies on Variability and Correlation for Nutrients, Biochemicals and Yield Contributing Traits in Brinjal (Solanum melongena L.)

Abstract

Vegetables are defined as the fresh parts of plants that provide suitable nutrition for humans, raw, cooked, canned, or processed in some other way. Brinjal is a commonly grown economically valuable crop, is an important solanaceous crop in India is a high genotypic diversity. In this study of variability and correlation of nutrient, biochemical parameters, and yield traits of diverse brinjal genotypes. Brinjal is a Wide variability was present among all the nutrients under study suggesting ample scope of selection. Genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) was high in most of the characters except moisture content, radical scavenging activity, and yield/plant. High heritability was observed for iron (99.70 %), copper (99.01 %), total anthocyanin (99.12 %), total phenol (98.59 %), total chlorophyll content (92.61 %), average fruit weight (98.82 %), number of fruits/plant (97.86), suggesting that selection for these traits would be effective for the selection. Correlation study shows that Moisture, P, Ca, TSS, total chlorophyll, fruit length, fruit girth, and a number of fruits per plant showed high significant positive correlation and Fe and Zn significant negative correlation with yield per plant at the genotypic level. This study shows that sufficient variability exists in all the cultivars for nutrients, biochemical parameters, and yield traits.
