Biochemical analysis of low chilling apple varieties in Assam

The present experiment was conducted with 3 low chilling apple varieties viz., HRMN-99(V1), Dorsett Golden (V2) and Anna (V3) at the Department of Horticulture, Assam Agricultural University, Jorhat during 2023-24. The experiment was laid out in Randomized Block Design (RBD) with seven replications. For fruit biochemical parameters a statistically significant variation was observed with the highest TSS (11.53oB), TSS: acid ratio (19.54), pulp: peel ratio (23.89) and juice content (40.59%) were recorded in V3. The highest anthocyanin (12.09 mg/100 g) and vitamin C (20.37 mg/100 g) were recorded in V1. The highest total sugar (5.73%) and shelf life (5.19 days) were noted in V2. Thus from the study, V3 (Anna) was found to be superior in terms of highest TSS while V2 (Dorsett Golden) had the maximum shelf life and V1 (HRMN-99) recorded the highest anthocyanin content.
