An experiment was conducted at the Division of Vegetable Crops, ICAR-Indian Institute of Horticultural Research, aimed to
characterize 480 indigenous and exotic brinjal accessions received from the National Genebank, ICAR-NBPGR, New Delhi. A lot of
variability was observed for agro-morphological traits recorded such as mean plant height (88.80 cm), plant spread (53.25 cm),
number of primary branches 5.0, leaf length 19.26 cm, leaf width 13.03 cm, days to fifty per cent flowering 50.00, fruit length 11.18 cm,
fruit breadth 4.83 cm, number of fruits per plant 14, average fruit weight 80.15 g, yield per plant 1.13 kg and 100 seed weight 0.5 g. The
Principal Component Analysis (PCA) indicated 100% of the total variation based on 12 phenotypic traits. There was a significant
positive relationship found among the fruit characters. The majority of the characters studied had high PCV, GCV, heritability, and
GAM levels. The brinjal accessions, such as EC316273-X, EC-396492, EC-467275, IC-0090851, IC-0090891-Z, IC-0090858, IC-0090898,
EC-384615, IC-0090762, IC-0090774 and IC-090922-X had shown high variability for quantitative characters.
