摘要/Abstract

摘要： 为研究莫桑比克腰果品系对白粉病的抗性，筛选出对白粉病具有抗性的腰果品系。在莫桑比克楠普拉省，调查了白粉病在60个腰果品系果实上的为害状况。结果显示，同一条件下，各腰果品系坚果上的白粉病为害程度差异很大。其中，品系AC34和4.2VM受白粉病的为害程度最低，其次为AZA17/79、B4、H1和M96-2.3VM，其余品系的坚果为害率和为害指数相对较高。根据笔者调查中腰果对白粉病抗性的评价标准，60个腰果品系中，分别有高抗品系6个、抗性品系1个、中抗品系9个、感病品系21个、高感品系23个。感病品系和高感品系共占调查总数的73.3%，说明莫桑比克推广种植的腰果品系对白粉病抗性普遍较差。

Abstract: In order to study the resistance of cashew to powdery mildew disease in Mozambique, and find the cashew clones that are resistant to powdery mildew disease. In Nampula Province of Mozambique, the damage of cashew fruit of 60 cashew clones caused by powdery mildew disease was investigated. The result indicated that, under the same condition, the cashew nut damage degree of different cashew clones were different. The damage degree of AC34 and 4.2VM were the lowest. The next were AZA17/79, B4, H1 and M96-2.3VM. The damage rates and damage indexes of other clones were higher relatively. According to the resistance evaluation criteria of cashew to powdery mildew disease in this paper, there were 6 high resistant clones, 1 resistant clone, 9 medium resistant clones, 21 susceptible clones and 23 high susceptible clones in the 60 investigated cashew clones. The susceptible and high susceptible clones account for 73.3% of the total samples. The most cashew clones in Mozambique were low resistant to powdery mildew disease.
