Variability of jamun (Syzygium cumini L. Skeels) fruit genotypes for biochemical attributes

Jamun (Syzygium cumini L. Skeels) is a highly cross-pollinated crop and pollinated primarily by honey bees. Hence, out crossing variability are common in jamun. As most jamun trees are seedling origin, they show immense variation in their biochemical attributes. The present investigation was carried out during year 2022-23 and 2023-24 to assess variability of jamun fruit genotypes for biochemical attributes. During the survey, 20 jamun genotypes were selected from the University campus of Mahatma Phule Krishi Vidyapeeth, Rahuri, Ahmednagar district of Maharashtra, India. All these genotypes were evaluated for biochemical attributes for two years 2022-23 and 2023-24. Results indicated that, genotype RHRJ-7/1 showing maximum TSS (17.15 °B), TSS: acid ratio (39.48), total sugars (15.42 percent), reducing sugars (12.05 percent) and Sugar: acid ratio (35.49) while minimum was recorded by the genotype RHRJ-10/4. The lowest titratable acidity (0.44 percent) was observed in the genotype RHRJ-7/1 whereas the highest (0.55 percent) was recorded in RHRJ-10/4. Maximum non-reducing sugars (3.85 percent) was observed in the genotype HN-1, while minimum (1.61 percent) was recorded in RHRJ-14/1.
