Abstract : A long term cultivar evaluation experiment on mango was carried out in Ranchi, Bihar, India to study their adaptability performance and to identify promising cultivars for rainfed, sub-humid climatic condition of eastern India. Twenty promising cultivars of mango drawn from North, South, East and West zones of India were planted in 1986 and evaluated for canopy development, fruiting behaviour, yield and physicochemical characteristics of the fruits. The results indicated that some of the south (Mulgoa and Swarnarekha) and the west (Kesar and Vanraj) Indian cultivars did not bear fruit even after 10 years of planting. Genotypes showed considerable variation for most of the characters under study. Chausa attained greatest height (5.02 M), girth (74.0 cm) and volume (42.07 M3) whereas the highest average yield per tree was recorded in Langra (20.68 kg) followed by Bangalora (14.54 kg). However, the maximum cumulative yield upto 10 years of age was recorded in Bangalora (43.62 kg) which was closely followed by Langra (41.37 kg). The physicochemical characteristics of the fruits showed highly significant differences among the cultivars. The highest average weight of fruit (550 g) and pulp (427.75 g) was recorded in Bangalora while the highest total soluble solids (TSS) (24.20°B) and total sugar (18.67%) was recorded from Mallika. Chausa recorded the highest TSS/acid ratio and was adjudged the most palatable mango cultivar.
