In the present research study, which was conducted during 2019-21, the genetic diversity, existing among the indigenous germpalsm of jackfruit (Artocarpus heterophyllus Lam.) of northern Tripura state, was observed on the light Principal Component Analysis (PCA), depending on 32 (thirty-two) numbers of tree morphological and fruit physical as well as bio-chemical attributes. first Principal Component (PC 1) exhibited negative association with majority of these traits except, fruit stalk diameter, number of fruit per cluster, weight of fresh flakes with seed, weight of fresh flakes without seed and flake (bulb)/seed ratio, while second and third Components showed nearly equal negative as well as positive association with these quantitative traits of jackfruit under study. The combined scoring bi-plot of PCA revealed that majority of the important tree characteristics, yield attributes and fruit bio-chemical parameters were associated in the first quadrant with accessions of jackfruit, such as JF-12, JF-21, JF-30, JF-35, JF-11, JF-23 and JF-1
