Available from https://colostate.pressbooks.pub/pgrsuccessstories/chapter/peanut-npgs-germplasm-smut-resistance/ Interpretive Summary: The production of peanut (Arachis hypogaea L.) is a multi-billion dollar global industry. One of the largest exporters of peanut, Argentina, faces devastating effects of the fungal pathogen peanut smut (Thecaphora frezzii Carranza & Lindquist). ARS has partnered with researchers in Argentina to identify peanut genotypes that are resistant to smut. These resistant sources will be used to develop resistant peanut varieties for global commercial peanut production. Technical Abstract: The production of peanut (Arachis hypogaea L.) is a multi-billion dollar global industry. One of the largest exporters of peanut, Argentina, faces devastating effects of the fungal pathogen peanut smut (Thecaphora frezzii Carranza & Lindquist). Through a collaboration between Argentina and the United States, 208 peanut genotypes were screened for smut resistance in a multi-year study to aid the peanut industry in Argentina and prevent the effects of peanut smut from impacting U.S. and global production. Eight accessions had a 0% disease incidence over three years of disease exposure. This evaluation has successfully identified resistant germplasm for protecting the future of peanut production in the United States, Argentina, and across the world. |
