国际马铃薯中心资源材料的引进、评价及利用

Introduction,evaluation and utilization of potato genetic resources from international potato center(CIP)

引进国内外不同基因型种质资源材的实生种籽、试管苗、早代无性系及品种材料等,经过多年培育从中直接筛出新品种、系5个和一批不同基因型的主要亲本材料,创新培育新品种2个及一批新的无性系,以供育种和四川省生产应用,有的已成为四川主栽品种。经筛选出的资源材料其基因类型丰富,具有属高抗晚疫病、病毒病以及抗其它病害,丰产性强,食口及加工品质好,耐贮、休眠性浅等不同特性,有相当利用价值,可进一步探索和应用。

The hybrid seeds, tube plants, clones and varieties were introduced for cultivation, selection, evaluation and utilization. 5 varieties were released ,3 clones and some main parents were selected,of which, 2 new varieties, some advanced clones were bred.The selected genetic resources with high yield, resistance to late blight, viruses and other diseases, nice tuber quality and stockpile were utilized in breeding.
