Assessment of different elite mango varieties suitable for North western plain zones of Uttar Pradesh

Abstract

The evaluation of different mango varieties was conducted during 2019-20 and 2020-21. The experiment was laid out in a randomized block design (RBD) with four varieties, namely, Ambika, Pusa Arunima, Kesar, and Dashehari-51, each replicated three times. The plants were spaced at 4x4 m intervals. The results obtained demonstrated significant variations in various parameters, ranging from minimum to maximum values. The canopy spread ranged from 1.77 to 7.49 m, stem girth from 16.67 to 40 cm, number of fruits per plant from 21 to 118, fruit length from 92.04 to 123.28 mm, fruit width from 56.02 to 77.41 mm, and fruit weight from 202 to 591 g. However, the number of primary branches (2-3) and plant height (1.54-4.35 m) were found to be nonsignificant. Based on the morpho-economic traits, Pusa Arunima appeared to be a superior variety in terms of tree morpho-economic traits, while others were considered moderate. Considering the average number of fruits per plant and fruit weight (g) over a two-year period, Pusa Arunima clearly outperformed the other three varieties in terms of yield. Furthermore, Pusa Arunima, Kesar, and Ambika exhibited more marketable fruit traits. These findings emphasize the significant diversity among the examined mango cultivars. Therefore, it is crucial to protect and preserve these valuable genetic resources for future breeding programs aimed at developing novel and commercially viable cultivars.
