Abstract/ Executive Summary:

Twenty three eggplant cultivars and four wild species' of Solanum were tested against bacterial wilt (J'seuclomonas solanacearum Snuth) In artificially Inoculated nursery beds and in a naturally infected fields of Citrus and Vegetable Seed Research Centre, BARI, Joydebpur. Only one wild species Solanum torvum showed highly resistant while one cultivated variety 'Khotkhatia Long' and three wild species namely, S. mamusum, S. sisymbrifolium and Surratense gave moderately resistant reaction against the disease. Six cultivars namely K. G. Begun, Singnath, Pusukanti, plannpunli, Uttura and Isampurl were moderately resistant under field conditions but they gave varied reaction in the nursery beds.

Keywords: Eggplant, Bacterial wilt

Start Date: 00-00-1988

End Date: 00-00-1990

Program Area: Pest Management

Commodity: Brinjal

Objectives:

To evaluate the newly collected eggplant cultivars, advanced lines and their wild relatives for resistance to bacterial wilt.

Methodology:

Thirteen advanced lines developed through hybridization at Citrus and Vegetable Seed Research Centre (CVSRC), BARI, eight locally popular cultivars collected from different parts of the country, two exotic varieties of eggplant obtained from U. S. A. and four wild species of Solanum collected from Bangladesh and Japan were included in the study. The experiments were conducted at the central research station of Bangladesh Agricultural Research Institute (BARI) in artificially prepared sick nursery beds in 1988-89 and 1989-90 and in the naturally infested fields in 1989-90. Six nursery beds each having 3 sq.m. area were inoculated during June-August, 1988 by following the method of Me Carter (1973). Twenty days old seedlings of susceptible cultivar of eggplant (Pusa Purple Long) were grown in rows spaced 10 em apart. Plants were allowed to grow until 20 cm tall and then they were clipped at the tops. Inoculum of P. solanacearwn prepared from petridish cultures (grown at 35⁰C for 3 days on potato dextrose agar) in distilled water were sprayed on the clipped plants. When the plants showed wilting (above 90%), they were cut to soil level and incorporated into the soil.

Achievement/Findings:

The present results revealed that the variety 'Khotkhatia long' was moderately resistant to bacterial wilt which may be recommended as a resistant variety for commercial production. However, S. torvum has no commercial value in Bangladesh due to its bitter-test This species may be used in breeding programme to transfer its resistant gene(s) into cultivated eggplant variety or may be used as root stock for grafting the high yielding commercial varieties in order to produce wilt free crop.
