英文摘要	用DNA指纹图谱分析了甘薯(lpamoea batatas Larn)徐薯18和AB78-1品系及它们的正反交子代叶绿体DNA,结果显示子代叶绿体DNA指纹均与母本相同,而未发现与父本或双亲相同的指纹图谱,因此在该杂交组合中质体遗传方式为母系遗传。这个结论与先前根据细胞学研究所推测的甘薯质体遗传方式不同,表明旋花科植物可能并不存在一个一致的父系或双亲质体传递模式。DNA指纹图谱分析用于质体遗传的研究尚未见报道,本文对其优越性进行了讨论。; The inheritance of chloroplast DNA (cpDNA) in sweet potato (Ipomoea batatas Lain.) was analyzed using DNA restriction fingerprinting. The cpDNA fingerprints of hybrids from reciprocal crosses between Xushu18 and AB78-1 were found to be identical to those of their female parents, which reveals that cpDNA of sweet potato is maternally inherited in this intervarietal crossing. This maternal cpDNA transmission pattern does not accord with the putative one based on former cytological studies. The plastid inheritance in Convolvulaceae has been briefly reviewed in this study, and the utility of DNA restriction fingerprinting analysis in the study of plastid inheritance is also discussed.; SCI(E); 中国科学引文数据库(CSCD); 1; 01; 73-75; 45
