稻瘟病是我省水稻的主要病害,全省各地每年都有不同程度发生,特别山区更为严重。近几年来,在毛主席革命路线指引下,各地大力推行以选用抗病良种为中心的综合防治,收到显著的成效。但是,现有的抗病品种远不能适应生产发展的需要,并且一个抗病品种,经多年种植,往往出现抗病性丧失。因此,不断鉴定、选育新的抗病品种和抗源材料,是夺取水稻进一步高产稳产的重要措施。为此,我们将本省收集的980份早晚稻品种和材料,在我系农场(福州连坂)进行叶瘟人工接种鉴定,并对其中部分品种进行穗瘟鉴定。现将初步结果整理如下,供参考。
Rice blast is the main disease of rice in our province, varying degrees every year throughout the province, especially in the more serious mountainous areas. In recent years, with the guidance of Chairman Mao’s revolutionary line, various localities have vigorously promoted the comprehensive prevention and treatment centering on the use of disease-resistant varieties and have received remarkable results. However, the existing resistant varieties are far from being able to meet the needs of the development of production. And a resistant variety, after years of planting, often shows a loss of disease resistance. Therefore, continuous identification and selection of new resistant varieties and anti-source materials are important measures to seize more high and stable rice. To this end, 980 varieties of early and late rice varieties and materials collected in our province were identified for artificial inoculation of leaf plague in our department farm (Lianzhou, Fuzhou), and some of them were identified as panicle blast. The preliminary results are summarized below, for reference.
