Abstract

Aim: The study was carried out to develop high yielding hybrids resistance to brinjal fruit and shoot borer (BFSB) and bacterial wilt.

Materials and Methods: It was taken five purple and green colored egg plant F₁’s at experimental farm of Bangladesh Agricultural Research Institute, Gazipur, Bangladesh.

Results: Wide-ranging of hybrids were significant for reaction to all characters (P<0.05). The hybrid F₁ 20x5 required minimum 100 days to first harvest. Maximum marketable fruit number was obtained by F₁ 1x19 (33.00).Heavy sized fruit was harvested by F₁ 1x5 (175 g), followed by F₁ 13x12 (156 g), F₁ 14x5 (151 g). The range of fruit infection by BFSB was 10.66 -18.00 %, while lowest in F₁ 13x12 (10.66 %). In case of bacterial wilt (BW) infestation at field level performance, zero percent incidences was observed in F1 1x19, F1 13x12, BARI Hybrid Begun-2. The yield range of eggplant hybrids was 24.93- 48.03 t/ha. The highest fruit yield was recorded from the line F₁ 1x5 (48.03 t/ha), followed by F1 1x19 (45.01 t/ha), F₁13x12 (39.23 t/ha). Though the yield was higher in the hybrids F₁ 1x5, F₁ 1x19, F₁ 13x12 but in view of earliness, resistance to infection by BFSB, bacterial wilt infestation, eye-catching fruit shape and color, F₁ 1x19 (purple colored hybrid) and F₁ 13x12 (green colored hybrid) were found promising.

Conclusion: It was concluded that these two hybrids viz., F₁ 1x19, F₁ 13x12 can be selected for the farmers of Bangladesh.
