Abstract:
A field experiment was conducted at ASPEE College of Horticulture and Forestry, Navsari Agricultural University, Navsari, Gujarat, India during the year 2019-20 and 2020-21 to study the phenological development in mango varieties viz., V_1: Sonpari, V₂: Alphonso, V₃: Amrapali, V₄: Kesar, V₅: Dashehari, V₆: Totapuri and V_7: Rajapuri. From this study it was revealed that, in a calendar year, occurrence of different phenophases viz., flower bud differentiation, panicle initiation, initiation of flower opening, attaining grain, pea and marble stages fruits were earlier in Alphonso, Kesar and Rajapuri and these were late in all rest of the cultivars. The major highlighting thing of this investigation was maturity of Sonpari and Dashehari, these cultivars stared flowering and its subsequent earlier phenophases comparatively late than early flowering varieties viz., Alphonso, Kesar and Rajapuri. However, these cultivars matches the maturity time with Alphonso. So it can be stated that Alphonso, Sonpari and Dashehari were early maturing than Kesar, Rajapuri, Dashehari, Totapuri and Amrapali. The significant variation in days to attaining different phenophases, among different mango varieties was recorded. Cultivar Sonpari and Dashehari required minimum duration to attained most of the phenophases and in case of Alphonso, Kesar and Rajapuri it was maximum.
