Abstract
稻熱病抗性檢定是水稻抗病育種的基礎工作，可做為育種材料篩選之依據，亦有助於擬定抗病育種新策略。本試驗自2003年至2008年於嘉義農業試驗分所及臺東關山兩處稻熱病統一檢定病圃，針對臺灣九個稻作改良場所提供之水稻品種（系）進行稻熱病抗性檢定。
Breeding rice (Oryza sativa) for resistance to blast disease caused by Magnaporthe grisea (synonym Pyricularia oryzae) is an important strategy for control of this disease in Taiwan. Field trials were conducted in disease nurseries (one paddy field and one upland field in Chiayi and one paddy field in Kuanshan) in Taiwan, during 2003-2008 to screen 1161 varieties and lines of rice collected from nine research institutes and extension stations in Taiwan for resistance to leaf blast and/or panicle blast. Results showed that, among Japonica rice tested, the number of varieties/lines with resistance to leaf blast was higher than the number with resistance to panicle blast.
