水稻抗稻熱病統一病圃自民國63年至78年,16年間先後計檢定2,118個水稻品種(系)。水稻罹病情形因年度及地區而異。一般言之,稉稻品種(系)較秈稻者易罹稻熱病,尤以穗稻熱病為甚。稉稻品種(系)在第1期作亦較第2期作容易罹病,而秈稻者適相反。水稻品種(系)對葉與穗稻熱病之抵抗性反應成顯著之正相關,惟尚有少數例外。又水稻品種(系)在旱田式病圃對葉稻熱病之反應與其在水田式病圃者頗為一致,但其發病程度較水田式病圃者嚴重。本省育成之抗病品種目前多數已淪為感病,此顯示加強選育持久性抗病品種之重要性,尤其是稉稻。
A total of 2,118 rice varieties and selections were tested for their reaction to blast at two to five uniform blast nurseries during a 16-year period from 1974 to 1989. The incidence of blast varied with years and nurseries. In general, Japonica rices were more susceptible to the disease than Indicas, particularly to the panicle blast. Entries of Japonica type appeared more severe to blast in the first crop season while the Indicas were more sensitive in the second crop season. The reaction of rice varieties and selections to leaf blast was significantly correlated with that to the panicle blast, although a lack of agreement was observed in certain entries. Blast incidence recorded in the upland nursery was also observed to be closely related to that recorded in the paddy nursery, though the degree of incidence in the upland nursery was more severe than that in the paddy nursery. Unfortunately, most of newly developed blast-resistant varieties were easy to be breakdown and became susceptible within a period of 1 to 3 years after they were released for commercial cultivation in a wide area, this suggests the importance of developing more stable and longer lasting resistance to blast in rice, particularly for Japonica rice.
