| 摘 要： | 对收集的10份福建地方山药种质及外来引进的铁棍山药的主要农艺性状、品质特性比较与遗传多样性分析。结果表明:德化芹峰淮山、明溪薯产量高,口感好,肉色白,刨皮后较不易氧化,适于加工,德化紫薇淮山氨基酸含量在参试的山药品种中含量最高,口感好,产量仅次于德化大薯。经遗传多样性ISSR聚类分析,将10个品种分成4类。综合评价,德化芹峰淮山、明溪薯、德化紫薇淮山发展潜力较大,适于作为商品深加工原料。

| Abstract: | Main agronomic characteristics,quality criteria,and genetic diversity of 10 varieties of yam (Dioscorea polystachya)found in Fujian and Iron Yam (Dioscorea opposita)introduced from overseas were compared. The results showed that Dehua Qinfeng and Mingxi varieties had the properties of high yield,pleasing taste,white color,and being not easily oxidized after peeling,which were considered suitable for processing applications. Whereas,Dehua Ziwei yam had the highest amino acid content among all tested samples,with appealing taste and a yield only next to that of Dehua large yam. According to the ISSR cluster analysis on genetic diversity,these tested varieties were classified into 4 categories. A comprehensive evaluation on them concluded that Dehua Qinfeng, Mingxi and Dehua Ziwei yam were potential candidates as a raw material for value-added processed products. |
