In Georgia, peanut researchers create disease-resistant hybrids

Tridge summary

Georgia farmers are producing half of the U.S.'s peanuts, using traditional methods to combat disease. However, breeders are now trying to incorporate disease-fighting genes from peanut's wild relatives, aiming to make plants naturally resistant to disease and reduce the need for chemicals. University of Georgia horticulture scientist Ye Juliet Chu has developed three breeding lines from peanut's wild relatives, presented in the Journal of Plant Registrations, with at least one of these varieties also being resistant to tomato spotted wilt virus. The research aims to enhance the sustainability and profitability of peanut farming by incorporating disease resistance from wild species into modern peanut varieties.

Georgia farmers produce half the peanuts grown in the U.S. each year, using proven production practices to fight disease in the field. In fact, modern peanut varieties carry little genetic defenses against some of the more devastating diseases, so peanut farmers carefully consider when to plant, whether to irrigate and when to apply fungicide and insecticide to keep those diseases from infecting the plant. That regimen could become easier as peanut breeders work to mine peanut's wild relatives for disease-fighting genes that would make peanut plants naturally resistant to disease, while eliminating the need for some chemicals.University of Georgia horticulture scientist Ye Juliet Chu is the latest peanut researcher in the College of Agricultural and Environmental ...
