摘　　要：为明确马铃薯杂交组合YSP-4×陇薯7号杂种F1的4个优良无性株系(株系3、株系5、株系6、株系12)间在产量和营养品质及DNA水平上的遗传差异,采用田间农艺性状观测、常规营养成分测定方法及SSR分子标记技术对其进行了研究。结果表明:4个优良无性株系中,以株系12和株系6的产量及营养品质性状表现较为突出,前者为高产株系,后者为高淀粉株系;筛选出S 174和S 118适宜引物2对,PCR扩增建立了能识别出4个马铃薯杂种株系及其亲本的SSR指纹图。In order to determine the genetic differences of yield,nutritional quality and DNA level among 4excellently asexual lines（line 3,5,6and 12）from F1 hybrids of potato hybrid combination YSP-4× Longshu 7,the agronomic characters and conventional nutritional quality measurement methods and the SSR molecular marker technology were used for study.The results showed that the yield and nutritional quality traits of lines 12 and 6exhibit more prominent,of which the former was high yield line and the latter was high starch line;two suitable SSR primers S 174 and S 118 were screened for fingerprint establishment of 4potato hybrid lines and their parents.
