Documentation and diversity analysis by DNA fingerprinting of the indigenous Mango (Mangifera indica L.) germplasm of West Bengal
Journal Title: International Journal of Experimental Research and Review - Year 2017, Vol 11, Issue 3
Abstract
Mango (Mangifera indica L.) has been reported to have extensive diversity due to alloploidy, outbreeding, continuous grafting and phenotypic differences arising from varied agro climatic conditions in different mango growing regions. Characterization and documentation of local mangoes is important for identifying potential candidates for improved utilization of the genetic resource and future breeding. The districts of Murshidabad and Malda once famous for mango are now facing tremendous genetic erosion of the mango germplasm. More than 200 varieties of Mango were recorded during the time of the royals of these districts. This number has sharply declined in recent times. The traditional varieties are low yielding and are replaced by new high yielding hybrids. These varieties are also facing extinction because of the aggressive cultivation of Amrapali, Himsagar, Langra varieties of mango. Conservation of Mango (Mangifera indica L.) germplasm is of utmost importance. But for conservation extensive survey and proper documentation is necessary. This study is an attempt of the documentation of Mango varieties from Murshidabad and Maldah districts. The DNA fingerprinting data will also help in proper identification of mango varieties. The dendogram generated from the fingerprint show the genetic distance among the varieties. The mango germplasm diversity data generated will be important for future mango breeding and in implementing conservation strategies.
