? 2021 Elsevier B.V.This study presents an assessment of seasonal variation of biochemical traits for twenty one eggplant (Solanum melongena L.) hybrids. Data of five traits, ascorbic acid, total sugar, total anthocyanin, total phenolics content and total antioxidant capacity were recorded in kharif (August 2017– February 2018) and summer (February 2018 – June 2018) season and analyzed using univariate (ANOVA) and multivariate (PCA) analysis. Seasonal variations influenced expression of all traits, but the ranking of hybrids for total phenolics and anthocyanin content was very consistent between seasons. The highest phenolic compounds, ascorbic acid and antioxidant capacity was observed during summer months, when monthly average temperature was highest of the year. Total antioxidant capacity of the hybrids varied from 3.42 to 9.77 μ mol trolox equivalent/g in summer season, which is a 2.9 fold difference and total phenolic contents ranging from 18.63 to 40.38 mg/100 g, a 2.2 fold difference. Overall results indicate that in future breeding program of H8 (Muktakeshi × Swarna Mani), all the five traits are important for primary selection under high temperature stress. H16 (BRBL-02 × BRBL-04) has potential for improvement of traits like, total phenolics content and total antioxidant capacity under high and low temperature conditions.
