Genetic relationships were determined using (A) PCO analyses of 207 ISSR fingerprints obtained for fifteen populations collected from 3 regions. Designations for regions are: Upper Assam or UA (cultivated populations), Lower Assam or LA (cultivated populations) and Shillong plateau or SP (wild populations). Inset shows PCO analyses of ISSR fingerprints from eleven cultivated populations from Upper Assam and Lower Assam regions. Putative population genetic structure (B) was obtained with Admixture (+adm ISSR) and without Admixture (-adm ISSR) settings at K = 3 using ISSR data with STRUCTURE [59]. Each vertical bar represents a moth distributed into 1 of K colored clusters. Populations 1 (BK), 2 (MD), 3(NB), 4 (GP) and 5 (SK) are cultivated populations from Lower Assam (LA); populations 6 (MR), 7 (DM), 8 (D), 9 (KG), 10 (TB) and 11 (LK) are cultivated populations from Upper Assam (UA); populations 12 (HA), 13 (MN), 14 (TR) and 15 (AG) are wild populations from Shillong plateau (SP). Population acronyms are expanded in Table 1. Putative population genetic structure (C) was obtained with Admixture (+adm SSR) setting at K = 3 for 15 populations (189 insects) using SSR data as above.
