Abstract/ Executive Summary:

A study on the regional yield performance of eggplant hybrid lines was conducted at geographically distinct 3 locations viz., Joydebpur, Jessore, Ishurdi of Bangladesh Agricultural Research Institute, during the winter season of 2014-15. Three eggplant lines viz., F11x5, F11x19, F114x5 and BARI Hybrid begun 2 (as check) were included in the study. The Average highest marketable fruit number per plant (16.80) was produced by F1 14x5, while maximum fruit yield (29.20t/ha) was also produced by F1 14x5 followed by F1 1x5 (25.76 t/ha). The results of the present study revealed that the F1 14x5 and F1 1x5 were found promising. So it may be recommended that the hybrid line F1 14x5 may be released as a new hybrid variety.

Keywords: Eggplant hybrids, Regional yield trial, Yield contributing characters, Yield

Location: Joydebpur, Jessore, Ishurdi

Start Date: 00-00-2014

End Date: 00-00-2015

Program Area: Variety and Species

Commodity: Brinjal

Objectives:

To study the performance of the eggplant hybrids regarding yield and pest resistance in different locations of Bangladesh as well as to choose a good line to release as a new variety.

Methodology:

The experiment was conducted at geographically distinct 3 locations namely; Joydebpur, Jessore, Ishurdi of Bangladesh Agricultural Research Institute, during the winter season of 2014-15. Three eggplant hybrid lines viz.,F11 x 5, F11 x 19, F114 x 5 and BARI Hybrid begun 2 (as check) were included in the study. The seeds were sown on the seedbed during the last week of September 2014. Thirty days old seedlings were transplanted in the main field during the last week of October, 2014. 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 30 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 50% plant 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.
