| dc.description.abstract | Jackfruit (Artocarpus heterophyllus Lam.) is an important dryland horticultural tree, grows well with minimum care and maintenance. Jackfruit exhibits huge diversity with respect to fruit size, shape, pulp colour, etc. Thus, the study aimed at identifying the genetic diversity present in jackfruit genotypes for pulp colour was undertaken. Among the 20 genotypes studied, the fruit weight was higher in NSP (23.2kg), TN Bigtree (19.45 kg) and NEL (12.50kg); pulp weight per kg fruit was higher in Ashoka Yellow (720.50g), VRT-11 (719.50g), MK (676.00g) and Byrachandra (669.50g). Less number of bulbs per kg fruit was found in Lalbagh Madhura (8.5), KT-17 (9), NKT-3 (9.5) and Ashoka Red (10); bigger sized bulbs were observed in Lalbagh Madhura (67 g) and KT-17 (52.93g). Overall, the best genotypes identified from the study were Swarna, Lalbagh Madhura, Byrachandra, NSP, Ashoka Yellow and NEL and can be used for commercial purpose. Molecular diversity analysis was carried out using 22 SSR primers, among them six primers (SSR 9, SSR 10, SSR 30, SSR 34, SSR 45 and SSR 48) showed polymorphism among twenty genotypes. There was no polymorphic primer found for a distinct pulp colour. The genotypes were grouped in three clusters, with cream and yellow colour pulp in cluster I and II, followed by yellow, orange and red in cluster III. | en_US |
