Bitter Gourd Field Day

A Bitter Gourd Open Field Day will be held on 26 July 2022 at WorldVeg’s Research & Training Station at Kamphaeng Saen, Thailand to demonstrate WorldVeg's genetically broad based and fixed, top new bitter gourd lines of all the market segments bred through recurrent selection (short green spiny, short green smooth shiny, medium green spiny, medium green smooth shiny, long green spiny, long green smooth spiny, Vietnam segment, exclusive Pakistan segment). Gynoecious, predominantly female lines of short, medium, and long segment and WorldVeg's unique F1 hybrids identified through observational, preliminary, and advanced yield trials will be showcased as well. New sources of resistance to Tomato leaf curl New Delhi virus will also be demonstrated. All these materials will help you to breed breakthrough F1 hybrids, using this genetically diversified material developed through a decade of patience, perseverance, and strategic breeding initiative of WorldVeg's cucurbit breeding team.

After this Field Day, a Global Bitter Gourd Breeding Project "Growing new markets with better bitter gourd genetics: WorldVeg's monoecious, gynoecious and predominantly female lines of different market segments developed through recurrent selection to breed breakthrough hybrids" will be launched in September 2022 through APSA-WorldVeg Vegetable Breeding Consortium. More details will be provided later.
