Fruiting Behaviour and Fruit Quality of Different Mango Varieties under Changing Climate Scenario

A field experiment was conducted to study the impact of temperature and relative humidity on fruiting behaviour and fruit quality of different mango varieties in Central Plain Zone of Uttar Pradesh during the fruiting year 2017-18 in the Garden of the Department of Horticulture, C.S. Azad University of Agriculture and Technology, Kanpur. The experiment was laid out in Randomized Block Design with 3 replications. Seven varieties of mango were taken for study. Fruiting attributes as influenced by temperature and relative humidity differed significantly in different varieties. Chausa taken highest number of days followed by Amrapali, while Dasheri and Gaurjeet recorded earliest fruit setting. The maximum marble size fruit was noted in Chausa while maximum mature fruit was noted in Local. The maximum fruit drop was recorded under Chausa followed by Dasheri, whereas minimum fruit drop was recorded under Local. Gaurjeet mature first (24th May) followed by Bombay Green (25th May) and Husnara (30th May). Chausa (26th June) and Amrapali (10th July) mature late and very late respectively. The maximum fruit length and width was found in Chausa among all of the varieties followed by Dasheri in length and Husnara in width. The maximum weight of fruit, fruit pulp, stone and peel was recorded in Chausa followed by Husnara (except peel weight), while, the maximum pulp % was recorded in Amrapali. The variety Gaurjeet and Bombey Green both mature first (71 days) followed by Husnara (75 days) while, Amrapali taken longest duration (124 days) followed by Chausa (109 days) and Local (104 days). It has been observed that during fruit setting and fruit development and maturity mango requires less RH as compared to panicle initiation. During growth and maturity RH positively correlated like temperature in all the varieties. It is concluded that mango variety Chausa being maximum in fruit weight, fruit pulp, stone and peel and medium maturing may found suitable for this region.
