1. Introduction
Mango (Mangifera indica L.) belonging to family Anacardiaceae isone of the commercially important fruit crop of India originated inthe Indo-Myanmar region.
Mango breeding programme is underway at several research institutes of India and several new releaseshave been reported over the last few decades.
Indian Agricultural Research Institute, New Delhi is notable among them credited with the development of some commercially important mango hybrids with desirable traits for domestic as well as overseas markets.
Existing diversity of mango with respect to important traits provides huge scope for breeding new cultivars with desirable characters (Ram and Rajan, 2003).
Flowering period in mango in India range from November to April depending on agro-climatic zones and mango breeding programmes are on several occasions hampered by spatial and temporal isolation of the parents (Chaudhury et al.,2010).
