Evolution of guava genotypes for bio-chemical, yield, and quality attributes

Abstract

The present investigation was conducted at Department of Horticulture, MPKV, Rahuri with twenty genotypes of guava during winter season of 2022 and 2023. Data was statistically analysed using descriptive statistical methods. The investigation focused on biochemical, yield and quality characteristics of genotypes. Results revealed that, highest total soluble solids (TSS) (13.86 °Brix) and lycopene content (1.52 mg/100 g) were observed in genotype T3 P19. However, genotype T17 P10 exhibited the highest TSS: acidity ratio (33.00), total sugar (8.24%), reducing sugar (4.19%), and the lowest acidity (0.38%). Analysis of yield attributes showed significant variation among the genotypes. Genotype T17 P10 also demonstrated superior fruit characteristics, including the highest fruit weight (220.49 g), maximum number of fruits per tree (37), yield per plant (7.87 kg), and overall acceptability (8.30). Based on these findings this study identifies promising guava genotypes that have potential for future crop improvement programs.
