Abstract:
A field experiment was conducted during 2017-18 in the Garden, Department of Horticulture (Fruit and Fruit Technology), Sabour, Bhagalpur.The experiment consisting of seven treatments was set up in randomized block design with four replications. The Seven released mango cultivars viz., Alfazli (Alphonso x Fazli), Hybrid 60-1 (Sunder Prasad x Langra), Jawahar (Gulabkhas x Mohmoodbahar), Menaka (Selection from Gulabkhas), Prabhashankar (Bombai x Kalapadi), Sabari (Gulabkhas x Bombai), Sunder Langra (Langra x Sunder Prasad) were chosen to study the effect of pollen viability and germination in different mango cultivars. The results revealed that the maximum viability percentage was measured in cultivar Prabhashankar (86.5%) followed by Alfazli (85.5%), Sabri (83.5%), Menaka (83.25%), Jawahar (81.75%) and Sunder Langra (80.75%). The cultivar Hybrid 60-1 (76.25%), had the minimum pollen viability percentage. The maximum germination percentage was measured in cultivar Prabhashankar (76.5%), followed by Jawahar (67.5%), Alfazli (65.75%), Menaka (63.25%), Sabri (61%) and Sunder Langra (55.25%). The cultivar Hybrid 60-1 (52.5%), had the minimum pollen germination percentage. The cultivars differed significantly in number of fruit set. Among the cultivars evaluated, earliest period of fruit set was found in cultivar Prabhashankar (26 days).
