Abstract

Ten mango cultivars namely ‘Amrapali’, ‘Kesar’, ‘Rajapuri’, ‘Langra’, ‘Alphanso’, ‘Dashehari’, ‘Chausa’, ‘CISH-M-1’, ‘DC- 1’ and ‘Mallika’ were evaluated during 2008–‘09 and 2009–‘10 for morphological and physiological parameters at Bikaner, Rajasthan. ‘Kesar’ had least field mortality (9.0%) and better growth performance, followed by ‘Amrapali’. Under the adverse environmental conditions of the site, ‘Langra’ and ‘Dashehari’ had the two highest specific leaf areas (SLA), while ‘Kesar’ registered the maximum chlorophyll content (a, b, and total), highest net photosynthesis (Pn; 5.38 μmole m–2 s–1), and transpiration rate (E; 2.27 mmole m–2). Overall, ‘Kesar’, ‘Amrapali’, and ‘Rajapuri’ were better performing genotypes under the hot arid environment in the initial year of establishment.
