Screening of Six Parents and 15 Cross Combinations against Bacterial Wilt (Ralstonia solanacearum)-Juniper Publishers
Journal of Agriculture Research - Juniper Publishers The study on the screening for resistance to bacterial wilt (Ralstonia solanacearum) of six parents and 15 cross combinations/hybrids were evaluated under artificial epiphytotic conditions at the Plant Pathology lab and glass house of Plant Pathology Section of Horticulture Research Centre (HRC) of Bangladesh Agricultural Research Institute (BAIR), Gazipur, Bangladesh during the period from September 2016-17 to develop high yielding F 1 eggplant varieties resistant to bacterial wilt. Amongst the six parents and 15 hybrids, six hybrids viz., F 1 4x17, F 1 4x5, F 1 18x17, F 1 3x17, F 1 3x5, F 1 17x5 showed resistant (R) reaction. The cross F 1 3x17, F 1 17x5 exhibited the lowest percent of wilt (10%) followed by F 1 4x17 (16.67 %), F 1 3x5 (13.33 %). In case of parents, three parents showed resistant (R) reaction viz. BL083 (20.00% wilting), BL081 (16.67% wilting) and BLS2 (16.67% wilting). Incubation pe...
