Carrington Research Contributes to Release of Sclerotinia-resistant Sunflower Lines
The USDA ARS Sunflower Unit has recently released three Sclerotinia resistant germplasm lines. In testing at misted nursery trials in three successive seasons, the three lines showed an average head rot incidence of 16, 33, and 8 percent compared to 58 percent for four commercial cultivars used for comparison. Misting nurseries originated at the Carrington Research Extension Center in 2001. It will take several years and multiple generations of crossing into existing hybrids before private seed companies will be able to release finished hybrids with the resistant traits.
