Seventy-four accessions of wild Arachis species along with a susceptible line TMV 2 belonging to A. hypogaea were evaluated for resistance to late leaf spot and rust under greenhouse environment. The experiment was conducted twice to confirm the resistance of the accessions. Percentage of leaf area damaged and disease score on a 1 to 9 scale for late leaf spot and rust were recorded for all accessions in both experiments. Additionally, percentage of defoliation was recorded for late leaf spot. One accession, ICG 8190, of A. hoehnei and one accession, ICG 13199, of A. duranensis were asymptomatic to late leaf spot in both experiments. In addition, 26 accessions were classified as resistant, 10 accessions were moderately resistant, and the remaining 36 accessions exhibited a susceptible reaction to late leaf spot. Only one accession, ICG 8954 of A. kuhlmannii, remained asymptomatic to rust in both experiments. All other accessions, except ICG 8206 of A. ipaensis, ICG 8197, ICG 8198, ICG 11549, and ICG 13178 of A. monticola, and ICG 13171 of A. stenosperma were classified as highly resistant to rust. Four accessions of A. monticola were susceptible to late leaf spot and rust.
在温室环境下，对74份野生花生属物种材料以及一份属于花生栽培种的感病品系TMV 2进行了晚叶斑病和锈病抗性评估。该实验进行了两次以确认这些材料的抗性。在两个实验中，记录了所有材料晚叶斑病和锈病的叶面积损伤百分比以及1至9级的病害评分。此外，还记录了晚叶斑病的落叶百分比。在两个实验中，一份霍氏花生（A. hoehnei）材料ICG 8190和一份杜兰花生（A. duranensis）材料ICG 13199对晚叶斑病无症状。此外，26份材料被分类为抗病，10份材料为中抗，其余36份材料对晚叶斑病表现出感病反应。在两个实验中，只有一份库氏花生（A. kuhlmannii）材料ICG 8954对锈病无症状。除了一份窄叶花生（A. stenosperma）材料ICG 13171以及四份蒙蒂花生（A. monticola）材料ICG 8206、ICG 8197、ICG 8198和ICG 11549外，所有其他材料对锈病被分类为高抗。四份蒙蒂花生材料对晚叶斑病和锈病感病。
