dc.description.abstractAn investigation on “Evaluation of bacterial wilt disease resistant green round prebreeding lines in brinjal (Solanum melongena L.)” was carried out in the research block of Department of Vegetable Science, COH, Bengaluru. Seven green round pre-breeding lines of F3:4 generation of Raidurga Green Round x West Coast Green Round along with their parents and checks (Arka Anand and Arka Kusumakar) were evaluated for interfamily and intrafamily variability along with bacterial wilt resistance after artificial inoculation. The results revealed that the range of variation between the average performance of lines was lesser when compared to intrafamily variability. None of the characters had shown high PCV and GCV estimates in interfamily variability studies indicates the lack of high variability between the average performance of segregating lines for these characters. The difference between PCV and GCV was comparatively higher in interfamily variability and it was lesser in intrafamily variability studies which indicated the characters were less affected by the environment within the line. High heritability with high GA and GAM was observed for yield per plant in interfamily variability studies, it indicated suggested good scope for selection between the lines for this character. Interfamily variability studies revealed high heritability coupled with high GA, GAM and GCV for fruit weight and yield per plant in all the lines indicating the major role of additive gene action for inheritance of these traits. Among the pre-breeding lines 12-23-30-1, 12-23-30-2, 12-23-249-10 and 12-23-249-12 were found resistant to bacterial wilt. Further 10 plants viz., 12- 23-30-1-41, 12-23-30-1-42, 12-23-30-1-32, 12-23-30-1-18, 12-23-30-1-7, 12-23-30-2-7, 12-23- 30-2-12, 12-23-249-10-54, 12-23-249-10-55 and 12-23-249-10-29 were selected based on fruit shape, fruit colour, yield and per cent bacterial wilt disease incidence for further evaluation of F4:5 generation.en_US
