Abstract/ Executive Summary:

An experiment was conducted to observe ten brinjal varieties namely BARI F1 Begun-4, Getco Hybrid F1 Begun, Metal Hybrid F1 Begun, BARI Begun-1, BARI Begun-6, BARI Begun-8, BARI Begun-9, BARI Begun-10, local genotypes Green ball and Singnath against brinjal shoot and fruit borer (BSFB) Leucinodes orbonalis Guenee and to determine their comparative level of resistance against BSFB and fruit-bearing performance under a natural photoperiod in winter season. The yield contributing characters viz., fruit length, fruit diameter, number of fruit plant^-1 and weight fruit^-1, shoot and fruit infestation and yield were recorded. The highest fruit length was recorded in BARI Begun-8, (26.23 cm) and the lowest was observed in local genotype Green ball (7.50 cm). Fruit diameter varied from 3.50 to 8.82 cm. significantly the highest number of fruit plant^-1 was harvested from BARI Begun-1 (25.56) and the lowest number from BARI Begun-6 (7.84). The highest number of healthy and infested fruit plot^-1 was obtained from BARI Begun-1 (306.67) and BARI Begun-8 (118.66), respectively and the lowest number of healthy and infested fruit plot^-1 was recorded from BARI Begun-9 (83.68) and BARI Begun-6 (48.04), respectively. Weight per fruit ranged from 60.30 to 180.13 g. The highest healthy and infested fruits yield plot^-1 was harvested from BARI Begun-1 (24.57 kg) and BARI Begun-8 (12.09 kg) and the lowest healthy and infested fruits yield plot^-1 was harvested from BARI Begun-9 (9.79 kg) and Green ball (4.21 kg), respectively. The highest number of shoot infestation plant^-1 was observed in BARI Begun-8 (0.65) and the lowest number in BARI Begun-1 (0.31). The BARI Begun-1 showed the rational level of resistance and remarkable fruit-bearing performance against BSFB.

Objectives:

To identify the relative level of tolerance and the good number of fruit-bearing brinjal genotypes.

Methodology:

The study was conducted at the experimental farm of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, Bangladesh during the winter season of September to March 2014-2015. Seeds of ten brinjal genotypes viz., BARI Begun-1, BARI Begun-6, BARI Begun-8, BARI Begun-9, BARI Begun-10, BARI F₁ Begun-4, Metal Hybrid F₁ Begun, Getco Hybrid F₁ Begun, Singnath and Green ball were collected from the Horticulture Research Center (HRC) of Bangladesh Agricultural Research Institute (BARI) and local market of Joydebpur, Gazipur, Bangladesh. The experimental plots were arranged in a randomized complete block design (RCBD) with three replications. The unit plot size was 3.0 m x 3.0 m. Plots and blocks were 1.5 m and 2.0 m apart, respectively. Brinjal plants were transplanted at a row distance of 1.0 m (3 rows in each plot) and plant spacing of 60 cm (5 plants in each row). Land preparation, manuring and fertilization and cultural operation were done according to Rashid (1999). Seeds of ten brinjal genotypes were sown in individual small nursery seedbed (3.0 m x 1.0 m). Thirty five-days old seedlings were transplanted randomly in the experimental plots. Data on different parameters viz., BSFB infestation, plant growth, yield contributing characters and fruit yield were recorded. The total number of shoots and the number of infested shoots were recorded from 5 plants randomly selected from each plot at 7 days intervals. At each harvest data on the number of healthy and infested fruits and their weight plot^-1 were recorded at 7 days intervals. All collected data analyzed by MSTAT-C Software. The analysis of variance (ANOVA) of different parameters was done and the means were ranked by using Duncan’s Multiple Range Test (DMRT).

Achievement/Findings:

Based on the findings of the present study, it may be concluded that the relative level of resistance and fruits bears performance against brinjal shoot and fruit borer among the tested 10 winter brinjal varieties, the BARI Begun-1 considering the rational level of resistance and notable fruit bearing performance.
