Abstract/ Executive Summary:

The study was conducted with 16 eggplant lines/ variety at the experimental field of Olericulture Division, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Gazipur during 2015-16 to select suitable lines for releasing as open pollinated eggplant variety. The lines varied significantly varied for their response to all characters. Line SM236C required 80 days to first harvest which was similar to SM 232 (81days) and SM23AC (81). Maximum marketable fruit number was obtained by SM236A (31.0), which was followed by SM232 (29.00), SM254 (28.67). Heavy sized fruit was harvested by BARI Begun 6 (223.9 g). The yield range of eggplant lines was 30.94-51.13 t/ha, while the highest fruit yield (51.13 t/ha) was recorded from the check variety BARI Begun 6 which was followed by SM236 A (49.95t/ha), SM236 C (50.47 t/ha).The range of fruit infestation by BFSB was 12.52-27.81 %, while minimum infestation was in SM236 A. Considering the yield contributing parameters studied three lines SM236A, SM236C and SM232 were found promising and may be recommended for AYT.

End Date: 00-00-2016

Program Area: Variety and Species

Commodity: Brinjal

Objectives:

To select suitable lines from this population to release as open pollinated variety (s) and utilize them in breeding program for improvement of eggplant.

Methodology:

The experiment was conducted at the experimental farm of Olericulture Division, HRC, BARI, Gazipur during the winter season of 2015-16. Thirteen eggplant lines/ variety viz., SM048, SM083A, SM203, SM204A, SM217, SM220, SM222B, SM232, SM236A, SM236C, SM253A, SM253B, SM254 and BARI Begun 5, BARI Begun 6 and BARI Begun 9 (check) were included in the study. The seeds were sown on the seedbed on 05 September 2015. Thirty days old seedlings were transplanted in the main field on 04 October, 2015. 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-B @ 10,000- 170-50-125-18-4.3-1.70 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. The intercultural operations (weeding, irrigation, insecticide spray etc.) were done as and when necessary. Data on days to 50% flowering, days to first harvest, marketable fruit number/ plant, average fruit weight (g), fruit weight/ plant (kg), fruit length (cm), fruit diameter (cm), plant height at last harvest (cm), fruit infestation by BFSB (%), fruit yield (t/ha), fruit shape and fruit colour were recorded from seven randomly selected plants per entry per replication. The information on different characters was statistically analyzed.
