EVALUATION OF SOME MANGO CULTIVARS UNDER NORTH INDIAN CONDITIONS

Five mango cultivars viz. Dashehari, Langra, Mallika, Amrapali and Alphanso were introduced at PAU, Regional Fruit Research Station, Abohar during the year 1982-83. These cultivars are being evaluated for their vegetative as well as fruiting behaviour. The plants of cultivar Langra have been observed to be vigorous while, Mallika, Dashehari and Amrapali closely followed each other whereas, the trees of Alphanso showed less vegetative growth. Maximum fruit yield (73.00 kg/tree) was recorded in the plants of Mallika which was closely followed by Dashehari while it was the minimum in Amrapali. Highest total soluble solids (20.04%) were recorded in the fruits of Dashehari which was closely followed by Langra, Amrapali and Mallika. The cultivars Dashehari and Langra matures during second week of July while, Mallika and Amrapali matures during the third week of July. The incidence of mango hopper was the highest in Mallika while, it was the lowest in Dashehari. The highest incidence of mango malformation was recorded in Mallika and lowest in Langra. Powdery mildew incidence was the highest in Amrapali followed by Alphanso, Dashehari and Langra whereas, its incidence was the least in Mallika. On the basis of fruit yield and quality attributes, the cultivation of Dashehari, Langra, Mallika and Amrapali is recommended for commercial cultivation in the south-western districts of Punjab.
