Abstract:
Polyploidy is a phenomenon, which is formed from meiotic aberrations related to spindle fibre formation. It is mainly of two types i.e. euploidy and aneuploidy. It may occur naturally or can be induced by artificial means. Polyploidy breeding is an important tool for widening variability in fruit crops with narrow genetic base like banana. It has really wide implications in obtaining bigger fruit size and disease resistant plant types. However, sterility has been seen as a general problem in most of such cases, which has to be taken care of before commercialization of polyploids.
