Inter tree variability in chips purpose jackfruit selections of Western Ghats of Karnataka, India

Abstract

The 62 jackfruit selections studied for chips purpose from the hilly (34 types) and coastal (28 types) zones of Karnataka in India were grouped into 6 clusters using Toucher’s values method employed on the Mahalanobis’s generalized distance (D²) values. Cluster A accounted for 45 selections followed by cluster B (10 selections) and cluster C (4 selections), whereas cluster D, E and F were solitary having single selection each. Inter cluster distance was maximum between cluster E and F (35.842) followed by cluster A and E (28.281) and was minimum between cluster C and D (9.362). The present study reveals that high chips yielding types have also recorded high dry matter content indicating a direct relationship between these characters. The relative contribution of characters clearly indicated that chips recovery contributed maximum for divergence (62.61%) followed by TSS (15.34%) and hence the selection of jackfruits for chips purpose should deem these characters.
