Abstract

The genetic diversity in 628 mulberry accessions (Indigenous-455 and Exotic -173) maintained in the ex situ field gene bank at CSGRC, Hosur was studied for a range of set descriptors on morphological, reproductive behaviour, leaf histological and growth behaviour. Wide variation was recorded in plant types, shoot colour, phyllotaxis pattern, and pubescence on the plant parts, leaf texture and shape and yield attributing characters. Indigenous accessions exhibited greater variation for most of the leaf histological characters compared to exotics. However, higher mean values contributed to leaf thickness was recorded in the exotics. Three major groups, viz. dioecious male, female and monoecious are recorded which indicate phenomenon of sexual polymorphism and prevalence of unisexuality, and preponderance of femaleness irrespective of its geographical and genetic origin. Exotic accessions performed better with higher mean values for most of the leaf characters while, indigenous accessions exhibited higher mean values for shoot characters. The promising accessions were identified for utilization in the breeding programmes.
