Multi-location preliminary field screening of World Vegetable Center bitter gourd breeding lines
For reaction to Tomato leaf curl New Delhi virus in selected hotspots in India
Abstract
Bitter gourd (Momordica charantia L.) is an economically and nutritionally important vegetable in Asia where approximately 400,000 ha is cultivated annually. Tomato leaf curl New Delhi virus (ToLCNDV) (genus Begomovirus, family Geminiviridae) is a significant biotic constraint to bitter gourd production throughout South Asia. Natural epidemics of ToLCNDV regularly occur on bitter gourd when populations of the vector whitefly (Bemisia tabaci) are abundant. Bitter gourd breeding lines, bred at World Vegetable Center Thailand, were evaluated in 3 major bitter gourd production areas in India ‒ Guntur (Andhra Pradesh), Jagdalpur (Chhattisgarh) and Bangalore (Karnataka) ‒ where natural epidemics of ToLCNDV regularly occur.
