Abstract:
The present investigation was carried out during 2019-20 in the Department of Horticulture (Fruit & Fruit Technology), Bihar Agricultural College, Sabour, Bhagalpur, Bihar. Twenty mango genotypes were taken for the experiment with the objective to study the phenological behaviour and incidence of malformation. Wide variability was recorded for different phenological traits. Earliest bud break and panicle emergence was recorded in the cultivar Zardalu (25^th January and 1^st February, respectively). Maximum flowering intensity with highest number of flowers panicle^-1 as well as maximum hermaphrodite flower was recorded in the cultivar Langra (77.87%, 943.00 and 69.44%, respectively). However, no malformation recorded in the cultivar Langra, Zardalu, Alphonso and Bombay. Hence, it could be concluded that the cultivar Langra, Bombay and Zardalu can be used in breeding programme for developing new hybrids having precocity in flowering with increased flowering intensity, maximum number of hermaphrodite flowers and resistance to mango malformation.
