摘要
白霉病(WM)、茎腐病和南方枯萎病是同一种土传花生(Arachis hypogaea L.)疾病的通用名称，这种疾病是由阿特利亚罗夫斯基(Curzi) C. C. Tu &;Kimbr。= Sclerotium rolfsii Sacc。番茄斑点枯萎病是由番茄斑点枯萎病毒(TSWV)引起的一种系统性花生叶面病害。本研究的目的是筛选几种目前可用的花生基因型(栽培品种和育种品系)，用于对这两种疾病的综合田间抗性。田间试验结果显示，花生对WM和TSWV的联合抗性在不同基因型间差异显著(P≤0.05)。总体三年(2018-20)平均值发现，与其他速生型花生品种相比，“乔治亚- 12y”的季中TSWV、季中晚TSWV+WM、季末WM+TSWV、挖掘后WM的发病率最低，豆荚产量最高。发现FloRun ' 331 '具有与Georgia-12Y相当的WM抗性，但也发现它对TSWV敏感。‘Georgia-14N’具有与‘Georgia-07W’相似的中度TSWV和WM抗性，也具有较高的根结线虫(RKN)抗性。
Field Screening for Tomato Spotted Wilt and White Mold (Stem Rot) Resistance among Peanut Genotypes
White mold (WM), stem rot, and southern blight are common names for the same soilborne peanut (Arachis hypogaea L.) disease caused by Athelia rolfsii (Curzi) C. C. Tu & Kimbr. = Sclerotium rolfsii Sacc. Tomato spotted wilt is a systemic foliar peanut disease caused by Tomato spotted wilt virus (TSWV). The objective of this study was to screen several currently available peanut genotypes (cultivars and breeding lines) for combined general field resistance to both of these diseases. Results from these field tests showed significant differences (P≤0.05) among the peanut genotypes evaluated for combined resistance to both WM and TSWV. The overall three-year (2018-20) average found that ‘Georgia-12Y’ had among the lowest percent incidence of mid-season TSWV, mid-late season TSWV+WM, late-season WM+TSWV, WM after digging, and the highest pod yield compared to other runner-type peanut cultivars. FloRun ‘331’ was found to have comparable WM resistance as Georgia-12Y, however it was also found to be susceptible to TSWV. ‘Georgia-14N’ was found to have moderate TSWV and WM resistance similar to ‘Georgia-07W’, and it also has a high-level of root-knot nematode (RKN) resistance.
