Online published on 25 May, 2023. Abstract Mango is a crop considered to have cultivation history of ubiquitous nature in India. A field experiment was carried out for five consecutive years (2015–19) at G.B. Pant University of Agriculture and Technology, Pantnagar to study the performance of two elite clones of Dashehari (namely Dashehari-35 and Dashehari-51) in comparison to commercially grown Dashehari mango. The observations on growth, yield and quality parameters were initiated in the year 2015, when plants started first bearing and continued up to the year 2019. Based on the five years of pooled data, the elite clone “Dashehari-51” was observed superior with respect to plant height, canopy volume, fruit weight, fruit yield and TSS as compared to elite clone Dashehari-35 or even commercial Dashehari. Significantly lower values related to different fruit quality parameters were noted in commercial Dashehari in comparison to elite clones of Dashehari. A 20.17% increase in yield was observed in Dashehari-51 coupled with higher B:C ratio (1.69:1) over commercially grown mango cv. Dashehari. Additionally, Dashehari-51 displayed far well-distributed vegetative and reproductive growth as the underlying reason for its bearing regularity imparting high yield potential. Thus, on the basis of yield superiority and fruit quality, the mango elite clone Dashehari-51 is proposed for its commercial cultivation in the sub-tropical region of Uttarakhand and adjoining states.
