An experiment was carried out with seven pre-breeding lines of F4 generation of green round brinjal derived from the cross Raidurga Green Round x West Coast Green Round to study the interfamily variability for nine different growth and yield parametes. None of the characters had shown high PCV and GCV estimates, which revealed lack of high variability between the average performance of segregating lines for these characters. Low PCV and GCV were recorded for plant height, number of branches per plant, days to first flowering, days to 50 per cent flowering, fruit length, fruit breadth and number of fruits per plant. Moderate levels of PCV and GCV were observed for yield per plant showing the presence of moderate variability for these characters between the lines whereas average fruit weight had recorded with moderate PCV and low GCV. 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 moderate GAM was recorded for average fruit weight. Estimation of per cent bacterial wilt incidence in each family revealed that four lines viz., 12-23-30-1, 12-23-30-2, 12-23-249-10 and 12-23-249-12 were found to be resistant.

Key words: Interfamily variability, Heritability, Genetic advance
