Abstract/ Executive Summary:

Evaluation of brinjal lines for the development of varieties resistant to insect and disease pests were conducted at the research field of Horticulture Research Centre, BARI with 17 brinjal lines planted in a split plot design during 2008-09 cropping season. No brinjal lines found resistant to brinjal shoot and fruit borer, jassid and whitefly. However, lines BB332 and EG193 were tolerant to brinjal shoot and fruit borer, lines BD2689 and BD2681 found tolerant to jassid and lines BB332 and BD2689 tolerant to whitefly. Lines BD2680 and BD2688 had the lowest incidence of bacterial wilt.

Keywords: Brinjal, Resistant, Insect and Diseases.

Location: HRC, BARI, Gazipur

Start Date: 01-09-2008

End Date: 01-02-2009

Program Area: Pest Management

Commodity: Diseases and insects

Objectives:

To identify brinjal lines resistant to insect and disease pests

Methodology:

The study was conducted at the experimental farm of Horticulture Research Centre, Bangladesh Agricultural Research Institute), Gazipur during 2008-09 cropping season under IPM-CRSP project. Seventeen brinjal lines Volanath, BD2689, BD2683, BD2682, BD2681, BD2680, BD2688, BD2640, Jamalpur-1, Jamalpur-2, Jamalpur-3, EG048, BD2684, S90, EG193, BARI Begun-8 and BB332 were tested. Seedlings were planted in the main field with split plot design. Individual plot size were 10m x1m and each plot consist of 17 lines with a inter plot spacing 50 cm. Data on number of shoot and later on fruit damage by BSFB, number of jassid and white fly on 3 middle leaves from each plant (line), number of healthy and borer infested fruits, number of marketable fruit and yield per plant were recorded.
