Louisiana State University (LSU) researchers and partners received a grant from the U.S. Department of Agriculture - National Institute of Food and Agriculture to develop sweet potato varieties resistant to guava root-knot nematode.


According to researchers at LSU College of Agriculture (AgCenter), guava root-knot nematode is one of the most damaging root-knot nematodes in the world. It can cause complete yield loss to important crops including tomatoes, cottonsoybeans, peppers, and sweet potatoes. It has a very high rate of reproduction and can multiply exponentially in a short span of time. The nematode was accidentally introduced to Louisiana.


The LSU AgCenter team, led by Tristan Watson, also received a sub-grant to support the research on sweet potato breeding and characterization of resistance mechanisms and associated genes, as well as the extension of research findings to regional and national stakeholders.
