Abstract/ Executive Summary:

The study was conducted with ten green type advanced F₁’s lines at the farm of Olericulture Division, HRC, Bangladesh Agricultural Research Institute, Gazipur during the winter season of 2017-18 to develop new high yielding hybrids having tolerance to eggplant fruit and shoot borer, bacterial wilt and little leaf. The lines varied significantly for their response to all characters (P<0.05). The hybrid F₁21x11required minimum 101.00 days to first harvest. Maximum marketable fruit number was obtained by two identical hybrids viz., F₁21X221B (33.60) and F₁220X11 (33.30), while heavy-sized fruit was harvested by F₁12X217A (142.22 g). The range of fruit infection by BFSB was 10.00 -20.66 %, while lowest in F₁21X221B, F₁220X221B, F₁13X221B (10.00 %). In case of bacterial wilt (BW) infestation at field level performance, zero percent incidence was observed in F₁12X11, F₁13X221B, F₁21X11, F₁21X221B, F₁220X11, F₁220X221B, BARI Hybrid Begun-4, while no infestation of little leaf disease was observed in these lines. The yield range of eggplant hybrids was 29.51 - 46.66 t/ha. The highest fruit yield was recorded from the hybrids F₁21X221B (46.66 t/ha), which was statistically similar F₁13X221B (46.01 t/ha), F₁220X221B (42.02 t/ha), F₁21X11 (41.98 t/ha), F₁12X11 (39.65 t/ha). Though the yield was higher in the hybrids F₁1x5, F₁1x19, F₁13x12 but considering earliness, tolerance to fruit infection by BFSB, bacterial wilt infestation, attractive fruit shape and fruit colour, the hybrids F₁12X11, F₁13X221B, F₁21X11, F₁21X221B, F₁204AX11, F₁220X221B were found promising. So these six lines can be selected for further confirmation.

Commodity: Eggplant, Diseases

Objectives:

To determined the study the performance of these ten hybrids regarding yield and having tolerance to eggplant fruit and shoot borer and bacterial wilt and phomopsis blight infestation disease.

Methodology:

The experiment was conducted at the experimental farm of Joydebpur during the winter of 2017-18. The experimental field was at 23.99⁰N Latitude and 90.41⁰ E Longitudes having an elevation of 8.2 m from sea level. Eleven eggplant hybrid/ varieties viz., F₁3X229, F₁12X11, F₁12X217A, F₁13X221B, F₁21X11, F₁21X221B, F₁204AX11, F₁220X11, F₁220X221B, F₁275X221B, BARI Hybrid Begun- 4were included in the study. The seeds were sown on the seedbed on 22 September 2017. Thirty-five days old seedlings were transplanted in the main field on 07 November, 2017. The experiment was laid out in a RCB design with three replications. The unit plot size was 7.5 x 0.70 m and 10 plants were accommodated in a plot with a plant spacing of 75 cm apart in single row maintaining a row to row distance of 1 m with 50 cm drain. The land was fertilized with cowdung, N, P, K, S, Zn and B @ 10,000 100, 30, 75, 13, 1.5 and 0.8 kg/ha, respectively. One-third of the cow-dung and half of P and full of S, Zn and B were applied during final land preparation. The rest of cow-dung and P and 1/3 of K were applied as basal in pit. Entire amount of N and rest of K were applied in four equal installments starting from 20 days after transplanting. Rest three installments were applied at the vegetative, flowering and initial fruiting stage. Irrigation, weeding, crop protection measures and other intercultural operations were done following standard practice. Data on days to 1st harvest, marketable fruit number/ plant, average fruit weight (g), fruit weight/ plant (kg), fruit length (cm), fruit diameter (cm), plant height at 1st harvest (cm), plant height at last harvest (cm), BFSB (%), bacterial wilt infestation (%), little leaf infestation (%) fruit yield (t/ha), fruit shape and fruit colour were recorded from five randomly selected plants per entry per replication. The information on different characters was statistically analyzed.

Achievement/Findings:

Though the yield of green coloured eggplant lines is generally lower compare to purple coloured eggplant, but consumer preferences for different green coloured fruit is much higher than purple coloured. Considering earliness, tolerance to fruit infection by BFSB, bacterial wilt and little leaf disease infestation, attractive fruit shape and fruit colour, last of all fruit yield, the lines F₁12X11, F₁13X221B, F₁21X11, F₁21X221B, F₁204AX11, F₁220X221B were found promising. So these six lines can be selected for further confirmation.
