It belongs to the family Solanaceae having chromosome number 2n=24. It is native of India and widely grown during summer and winter seasons. Major producing states are Orissa, Bihar, Karnataka, West Bengal, Andhra Pradesh, Maharashtra and Uttar Pradesh. It is an important crop grown in India with a production of 13.50 million tonnes in an area of 0.71 million hectares with average productivity of about 19.10 t/ha (Anon., 2014a). Eggplant has three main botanical varieties under the species melongena. The eggplant International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 2 (2020) Journal homepage: http://www.ijcmas.com An investigation was carried out to study the interfamily variability for nine different growth and yield parameters from the cross Green Long x IIHR-3 with ten pre-breeding lines of F 4 generation of green long eggplant. Low PCV and GCV were recorded for plant height, days to 50 per cent flowering, fruit length and fruit breadth. Moderate PCV and GCV was noticed for number of branches per plant, days to first flowering, number of fruits per plant and yield per plant. But the narrow difference between PCV and GCV indicated low environment effect. High heritability coupled with high GA and GAM was observed for yield per plant indicates predominant role of additive gene action. Whereas high heritability with high GAM was recorded for other traits like average fruit weight and number of fruits per plant. Estimation of per cent bacterial wilt incidence in each family revealed that five lines viz., 12-36-170-11, 12-36-46-3, 12-36-170-9, 12-36- 170-19 and 12-36-46-6 were found resistant.
