Evidence of a new Musa species - M. swarnaphalya in India and its confirmation through morpho-molecular characterization

Abstract

A new species, Musa swarnaphalya, Uma, Saraswathi and Durai, has been identified from Sessa village of Balukpong district in southern Arunachal Pradesh. It is characterised by its unique greenish-yellow colour male bud. Diploid status of this species was proven using flow cytometry and its identity as a new species was assessed through morpho-taxonomy and confirmed through RAPD and IRAP markers. M. swarnaphalya grouped with M. itinerans and M. nagensium in a distinct cluster confirming its stand within the section Eumusa. Freedom from pests and diseases in its place of distribution suggests its possible utility as a resistant gene source in future breeding programmes.
