Abstract/ Executive Summary:

A study on the performance of twelve eggplant lines with the variety BARI Begun 6, BARI Begun 8, BARI Begun 10 (check) were conducted at the experimental farm of Olericulture Division, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh during the summer season of 2016 to develop new OP summer varieties tolerant to eggplant fruit and shoot borer and bacterial wilt. The lines SM083D, SM222B, SM236A and SM259 took the minimum days to 1^st harvest which were identical and was 90.67 days. The highest number of marketable fruit/plant (40.16.) was found in SM083D while the lowest number of fruit was produced by BARI Begun 6 (21.03). The highest average fruit weight was obtained from BARI Begun 6 (130.33g) followed by SM253B, SM191B and the lowest fruits weight/plant was observed in SM259 (58.43g). The longest fruit was recorded from BARI Begun 10 (22.0cm) followed by BARI Begun 8 while the shortest was from SM253B (5.73 cm).The minimum fruit diameter was recorded from BARI Begun 6 (6.96cm) while the shortest was from SM259 (2.66 cm). Zero percent bacterial wilt mortality lines was observed in SM191B, SM203, SM222B, SM232, SM236A, SM259, SM267, BARI Begun 8, BARI Begun10. The highest per hectare fruit yield was recorded from SM083D (47.90 t) followed by SM222B (42.70 t), while the lowest was produced from SM233 (23.51 t). Minimum infestation by eggplant fruit and shoot borer was 7.67% was observed in SM269A followed by SM204 (8.48%) and maximum was observed SM233 (23.65%). Considering earliness, higher yield, pest and diseases tolerance, the lines SM083D, SM222B, SM232, SM259 and SM191B were found promising and may be recommended as RYT in next year.

End Date: 00-00-2017

Program Area: Crop-Soil-Water Management

Commodity: Brinjal

Objectives:

To develop new OP summer varieties tolerant to eggplant fruit and shoot borer and bacterial wilt.

Methodology:

The experiment was conducted at the experimental farm of Olericulture Division, Horticulture Research Centre (HRC), Bangladesh Agricultural Research Institute (BARI), Gazipur during the summer season of 2016. Twelve eggplant advanced lines and BARI Begun 6, BARI Begun 8, BARI Begun 10 (as check) were included in the study. The seeds were sown on the seedbed on March 15, 2016. Thirty days old seedlings were transplanted in the main field on April 14, 2016. The experiment was laid out in 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 30 cm drain. The land was fertilized with cowdung, N, P, K, S, Zn and B @ 10000, 100, 30, 75, 13, 1.5 and 0.8 kg/ha, respectively. One third of the cowdung and half of P and full of S, Zn and B were applied during final land preparation. Rest of cowdung 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. The intercultural operations (weeding, irrigation, insecticide spray etc.) were done as and when necessary. Data on days to 1st harvest, days required for harvesting, fruit length (cm), fruit diameter (cm), marketable fruit number/ plant, average fruit weight (g), fruit weight/ plant (kg), yield (t/ha), eggplant fruit and shoot borer (EFSB) infestation (%), plant height at 1st harvest (cm) and plant height at last harvest (cm) were recorded from seven randomly selected plants per entry per replication. The information on different characters was statistically analyzed.
