白霉病、茎腐病和南方疫病都是由同一种土传真菌--罗氏菌核引起的。与番茄斑枯病病毒引起的番茄斑萎病并存，造成栽培花生(花生)L的主要病害。这些病害问题是普遍存在的，不仅发生在美国东南部，而且发生在大多数花生产区。因此，越来越需要将基因抗药性作为减少这两种疾病组合造成的经济损失的最具成本效益的方法。在2004年至2008年的五年中，对佐治亚州花生育种计划中的几个先进育种品系和最近推出的花生品种进行了对这两种病原菌的联合抗性鉴定。多年来白霉病和TSWV抗性的最佳组合和多年最高产量始终出现在最近公布的中熟、扁平型花生品种乔治亚-07W、格鲁吉亚-03L和AP-3。然而，所有其他佐治亚州品种和佐治亚州优良育种系也被发现与对照品种C-99R和佛罗里达-07相似或显著优于对照品种C-99R和佛罗里达-07。(C)2009爱思唯尔有限公司。保留所有权利。
White mould, stem rot, and southern blight are caused by the same soilborne fungus, Sclerotium rolfsii Sacc. and when combined with tomato spotted wilt caused by Tomato spotted wilt virus (TSWV), result in major disease problems in the cultivated peanut (Arachis hypogaea L). These disease problems are universal and occur not only in the southeast U.S.A. but also in most peanut production areas. Consequently, there is an increasing need for genotypic resistance as the most cost effective way to reduce the financial loss due to the combination of these two diseases. During five years (2004-08), several advanced breeding lines and recently released peanut cultivars from the Georgia peanut breeding program were evaluated for combined resistance to both pathogens. The best combination of white mould and TSWV resistance and highest yield over Multiple years was consistently found in the recently released medium-maturity, runner-type peanut cultivars, Georgia-07W, Georgia-03L, and AP-3. However, all of the other Georgia cultivars and advanced Georgia breeding lines were also found to be either similar or significantly better than the check cultivars C-99R and Florida-07.
