Pumpkin is a popular vegetable in Bangladesh. It is a rich and cheap source of vitamins, especially carotenoid pigments. It can contribute to improved nutritional status, particularly for vulnerable groups. But, its production is seriously constrained due to the attack of WM2V disease. Farmers use pesticides indiscriminately, which is neither effective for pest control nor safe for consumers. Use of virus-resistant pumpkin varieties is the most practical method for pest control. A few moderately resistant pumpkin varieties have been identified at BARI. This project sought to obtain agronomically acceptable virus-resistant line(s) through confirmatory tests for on-farm use and also to use the resistant sources for developing high yielding, better quality pumpkin lines.
1. To identify the sources of virus-resistant pumpkin varieties/lines pumpkin through field tests and ELISA tests 2. To select agronomically acceptable virus-resistant line(s) for release as varieties
Evaluation of 40 selected pumpkin lines in the field and their tests for virus detection through ELISA showed that virus resistance is available in local pumpkin germplasm, and development of improved pumpkin varieties having satisfactory virus resistance is possible. Based on virus resistance and acceptable horticultural qualities six plants of five pumpkin lines were selected for advanced trials.
