Abstract/ Executive Summary:

The study was conducted with 13 eggplant lines/ variety at the farm of Olericulture Division, HRC, Bangladesh Agricultural Research Institute, Gazipur during the summer season of 2017 to develop new high yielding OP variety having tolerance to high temperature, high humidity, eggplant fruit and shoot borer, bacterial wilt and phomopsis blight.The lines varied significantly for their response to all characters (P<0.05). The line 286A required minimum 90.67 days to first harvest. Maximum marketable fruit number was obtained by SM323 (41.56). Heavy sized fruit was harvested by SM328 (111.84 g), which was statistically similar with SM275 (107.33 g), SM236A (97.00 g). The range of fruit infection by BFSB was 12.56 - 23.33 %, while lowest in SM236A (12.56 %). In case of bacterial wilt (BW) infestation at field level performance, zero percent incidences was observed in SM232, SM236A, SM286A, SM328. The yield range of eggplant lines was 12.47 - 39.72 t/ha. The highest fruit yield was recorded from the line SM236A (39.72 t/ha), which was followed by SM323 (34.50 t/ha), SM232 (34.28 t/ha), SM328 (32.49 t/ha), BARI Begun-10 (31.45 t/ha), SM286A (29.88 t/ha), SM275 (29.49 c t/ha) and lower yield were recorded from SM313 (12.47 t/ha). Considering earliness, tolerance to fruit infection by BFSB, bacterial wilt infestation, phomopsis blight infestation, attractive fruit shape and fruit colour, last of all fruit yield, the lines SM232, SM275, SM288, SM323, SM328 were found promising. So these five lines can be selected for further confirmation.

Keywords: Performance, Yield, Tolerance, High temperature, High humidity, Eggplant, Shoot borer

Location: Olericulture Division, HRC, Bangladesh Agricultural Research Institute, Gazipur Bangladesh

Start Date: 00-00-2017

End Date: 00-00-2018

Program Area: Crop-Soil-Water Management

Commodity: Eggplant

Objectives:

To study the performance of these lines regarding yield having tolerance to high temperature, high humidity, eggplant fruit and shoot borer, bacterial wilt and phomopsis blight.

Methodology:

The experiment was conducted at the experimental farm of Joydebpur during the summer of 2017. The experimental field was at 23.9917º N Latitude and 90.4124º E Longitudes having an elevation of 8.2 m from sea level. Thirteen eggplant lines/ varieties viz., SM232, SM236C, SM236A, SM267, SM275, SM286A, SM288, SM289, SM313, SM323, SM328, SM335, BARI Begun-10included in the study. The seeds were sown on the seedbed on 15 March 2017. Thirty two days old seedlings were transplanted in the main field on 16April, 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. 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 installment starting from 20 days after transplanting. Rest three installments were applied at 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), fruit infection by BFSB (%), bacterial wilt infestation (%), little leaf infestation (%),phomopsis blight 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 lines SM236A, SM323, SM232, SM328, SM286A were high yielded, considering earliness, tolerance to fruit infection by BFSB, bacterial wilt infestation, phomopsis blight infestation, attractive fruit shape and fruit colour, last of all fruit yield, the lines SM232, SM275, SM288, SM323, SM328 were found promising. So these five lines can be selected for further confirmation.
