The lines varied significantly for their response to all characters (P SM 083F required minimum 105 days to first harvest. Maximum marketable fruit number was obtained by SM083A (30.33). Heavy sized fruit was harvested by SM275 (175 g), followed by SM289 (170 g), SM279 (169 g), SM083E (165 g), SM253 (164 g). The range of fruit infection by BFSB was 10.33% - 19.007%, while lowest in SM262 (10.33%). In case of bacterial wilt (BW) infestation at field level performance, zero percent incidence was observed in SM262, SM275, SM279, SM291B. The yield range of eggplant lines was 18.62 - 43.36 t/ha. The highest fruit yield was recorded from the line SM 275 (43.36 t/ha), which was statistically similar with which was statistically similar with SM 279 (39.85 t/ha), SM 291B (38.59 t/ha), SM083B (38.42 t/ha), SM 262 (38.17 t/ha), SM 253 (37.43 t/ha). Considering earliness, tolerance to fruit infection by BFSB, bacterial wilt infestation, attractive fruit shape and fruit colour, the lines SM 275, SM 279, SM 291B, SM083B, SM 262, SM 253 were found promising. So these six lines can be selected for further confirmation.展开更多
