Last month, it was drought-tolerant corn. now, USDA agricultural research Service plant geneticist Tommy Carter and his team of researchers are preparing to release a line of drought-tolerant soybeans.

Carter and his colleagues have narrowed down the number of prospective varieties from more than 5,000 to five. These varieties display the slow-wilting trait, as well as good yield potential under normal rainfall conditions. Following one final round of testing, Carter hopes to release his drought-tolerant lines soon.

According to Carter, his slow-wilting lines yield four to eight bushels more than conventional varieties under drought conditions.
