摘　　要：于2002～2003年对大田橡胶品种初级系比和高级系比试验的76个品系对白粉病的抗性进行监测。结果表明:AC/S/12-42/276,RO/CM/10-44/454和RO/PB/1-2/56共3个品系表现为高抗;RO/CM/10-44/268、AC/X/21-64/12、RO/PB/1-2/124、RO/PB/2-3/385、MT/C/2-10/49、AC/B/17-58/24、RRIC130、RO/PB/2-3/284、AC/B/19-56/260和AC/F/7-38/63共10个品系表现为中抗;其余的品系都表现有不同程度的感病。AC/B/17-58/38和MT/VB/25-57/13这2个品系表现为高感。The resistance of76rubber clones to powdery mildew caused by Oidi um hereae was evaluated in2002and2003.The results showed that3clones,namely AC/S/1 2-42/276,RO/CM/10-44/454and RO/PB/1-2/56had high resistance to powdery mildew;10 clones,namely RO/CM/10-44/268,AC/X/21-64/12,RO/PB/1-2/124,RO/PB/2-3/385,MT/C/2-1 0/49,AC/B/17-58/24,RRIC130,RO/PB/2-3/284,AC/B/19-56/360and AC/F/7-38/63had moder ate resistance;while the others were susceptible to the disease,among which2clon es,namely AC/B/17-58/38and MT/VB/25-57/13were highly susceptible.
