✦ Synopsis
Progress of hybridization work at various centres in India is reviewed. With the improved technique of mango hybridization and the report of self-incompatibility in mango, it will be possible to evolve a larger number of hybrids for screening for desirable characters. Embryological studies have shown that in mango pollen tubes grow down the style and effect fertilization but the development of zygote is blocked leading to a sporophytic type of self-incompatibility. Hybrids recently evolved through the combinations of regular and commercial biennial bearing varieties indicate that largescale hybridization may offer a solution to the biennial bearing problem in mango.
EARLY HYBRIDISATION WORK
Almost all the mango varieties, at present under cultivation in India, are selections made from the open-pollinated seedlings during the course of 400 years or so. This process of selection of mango varieties has considerably been encouraged with the introduction of technique of inarching during the Mughal period (1650-1820), which was the bright period of mango improvement in India. Most of the reputed mango varieties, now under cultivation, were evolved by selection during that period and the subsequent years of Muslim rule. There are not many reports of further improvement during the interval.
