1986—1987年应用新的福建鉴别品种,鉴定了来自本省34个县(市)的240个有效单孢菌株,区分为7群25个中国小种,进一步划分为56个福建小种,其中ZG_1Ff_1和ZG_5Ff_1为优势小种。根据1986—1987年稻瘟病菌福建小种的区系组成及侵染主栽品种的小种出现频率,参号1978和1981年珍龙系统品种抗性丧失的实际情况,曾预计1988—1989年本省主要抗病品种78130系统、金早6号和矮梅早3号等不会在大面积上丧失抗瘟性,实践证明这个估计是正确的。双抗77001和谷农13,仍为抗谱较广的品种,可继续作抗稻瘟病育种的抗源。
From 1986 to 1987, a total of 240 validated single-species isolates from 34 counties (cities) of Fujian Province were identified, which were divided into 7 groups of 25 Chinese race breeds and further divided into 56 Fujian breeds. Among them, ZG 1 Ff 1 And ZG_5Ff_1 is the dominant race. According to the frequency of the race of Fujian races from 1986 to 1987 and the frequency of races of major cultivars invaded by Magnaporthe grisea from 1978 to 1981, The main disease-resistant varieties 78130 in our province, Jinzao 6 and Dumeizao 3 will not lose the anti-plague in a large area. Practice has proved that this estimation is correct. Double-resistant 77001 and Tanong 13 are still resistant varieties of broad spectrum, can continue to fight resistance to blast resistance breeding.
