An extensive survey was conducted in different District (Upper Siang, West Siang and East Siang) of Arunachal Pradesh during 2015-17 to study the genetic diversity of carambola and to identify superior genotypes having sweet in taste based on the descriptor of NBPGR carambola. The experimental result showed that individual fruit weight ranged from 83.53 g (P20) to 300.00g (P14); fruit diameter 4.07 cm (P5) to 9.13 cm (P14); fruit length 6.83 cm (P4) to 15.93 cm (P14); juice content 25.00 ml (P4) to 61.67 ml (P14); seed/fruit 2.00 (P1) to 4.67 (P12); fruit yield 84.33 kg (P4) to 185.00 kg/tree (P8); TSS 5.03 (P12) to 14.97 0Brix (P11); oxalic acid 0.01% (P2, P3, P5, P7, P8, P14 and P18) to 0.35% (P9); ascorbic acid 25.00 (P17) to 68.00 mg/ 100g (P9); acidity 0.08 % to 1.22 %; reducing sugar 3.20 % (P3) to 11.93 % (P11); total sugars 3.40 %(P3) to 12.80% (P11) and shelf life 10.67 days (P10) to 14 days (P17). Based on the results obtained from the present investigation, it can be concluded that, selected carambola genotypes exhibited noticeable variation in the morphological, biochemical and yield characters. SDS-PAGE analysis also showed considerable variation in band number of protein which ranged from 14-38. Thus, these findings illustrated the usefulness of physic-chemical characterization and biochemical marker as a tool for the genetic diversity evaluation in carambola.
