Abstract:

The present investigation was carried out during 2010-12 to establish the correlation among flowering, pollen viability and malformation in 15 mango cultivars namely Amrapali, Bhadauran, Dushehari, Erwin, Husnara, Janardan Pasand, Langra, Mallika, Neelum, Primor de Amoreira, Pusa Arunima, Sensation, Tommy Atkins, Totapuri Red Small and Zill at the Division of Fruits and Horticultural Technology, Indian Agricultural Research Institute, New Delhi. The flowering duration had significant positive correlation with days required for 50% bloom, per cent hermaphrodite flowers and had significant negative correlation with in vitro germination of fresh pollen. Per cent hermaphrodite flowers had negative correlation with total flowers and pollen viability. Total number of flowers showed significant positive correlation with per cent male flowers but negative correlation with hermaphrodite flowers percentage. The malformed panicle had positive correlation with day required for 50% bloom and had negative correlation with panicle length. Thus, on the basis of results it can be concluded that correlations among flowering, pollen viability, and malformed panicles are pre- requisite for any of the breeding programme. Direct selection may be followed for the improvement of mango for these characters.
