菲律宾马铃薯主要种植在高原Bengue省和Mt省。马铃薯晚疫病是马铃薯生产的主要限制因素。农民采用抗病品种 ,栽培措施和杀菌剂等综合措施防治晚疫病。从 2 0世纪 80年代起 ,菲律宾从CIP引进许多马铃薯种质资源 ,与CIP进行合作 ,开展了杂交育种研究 ,主要目标是 :(a)结合对晚疫病和金线虫 (Globoderarostochiensis)的抗性 ;(b)改良抗晚疫病无性系的当地适应性 ;(c)将加工性状组合到抗晚疫病品种中去。主要成果 :①选出 4个抗晚疫病品种 ,并向农民推广 ;②两个品种Igorota和Solibao经过改良 ;③选择引进了具有适应性好和高产的品种Disco ,Columbus ,Hermes ,Agria,Snowden和Atlantic ;④大多数菌株对瑞毒霉是抗性的或中抗的 ;⑤推广抗病品种Igorota和Solibao可减少 5 0 %化学防治费用
Filipino potatoes are mainly planted in the plateaus of Bengue and Mt provinces. Late blight of potato is a major limiting factor in potato production. Peasants use the integrated measures of disease-resistant varieties, cultivation measures and fungicides to prevent and control late blight. Since the 1980s, the Philippines has introduced many potato germplasm resources from CIP, cooperated with CIP and conducted crossbreeding research. The main objectives are: (a) to combine resistance to late blight and Globoderarostochiensis; (b) improving local adaptability to late blight resistant clones; and (c) combining processing traits into resistant late blight cultivars. The main results were as follows: ① Four varieties of late blight resistance were selected and popularized to peasants. ② Two varieties of Igorota and Solibao were improved. ③ Disco, Columbus, Hermes, Agria, Snowden and Atlantic; ④ Most isolates were resistant or resistant to rubella; ⑤ Popularization of resistant varieties Igorota and Solibao reduced the cost of chemical control by 50%
