摘　　要：‘心香’是一个早熟、优质的迷你甘薯品种。本研究阐述了近年来‘心香’的营养成分、食味、香味等品质研究和育种利用进展。研究表明,‘心香’不仅具有较高的碳水化合物含量,而且含有丰富的活性功能成分。‘心香’甘薯熟化后含有大量的醛类和杂环类等特征香气,烤薯的重要香气成分苯乙醛、麦芽酚尤其丰富,同时各种香气种类有很好的多样性,比例较为协调。采用烤、蒸这两种加热熟化方式以及20~45 d贮藏期有利于迷你甘薯‘心香’获得更好香味和质构特征。生长前期的根系中含有较高的蔗糖分解酶活性,尤其高转化酶活性是‘心香’早熟优质、结薯个数多的重要原因,生育期80~100 d时收获有更好的营养和食味品质。后代品种能够较好地继承‘心香’的品质优势。利用‘心香’的早熟优质特性,加强迷你甘薯的新型种植制度应用和育种利用。’Xinxiang’is an early-maturing and high quality mini-type sweetpotato variety.In this study,the research progress of quality traits including nutritional components,taste and aroma,and breeding utilization of’Xinxiang’in recent years were reviewed.The studies showed that’Xinxiang’not only has a high carbohydrate content,but also contains rich active functional components.After being cooked,’Xinxiang’contains a lot of characteristic aromas such as aldehydes and heterocycles,especially phenylacetaldehyde and maltol,which are important aroma components of baked sweetpotato.At the same time,there are various aroma types with good diversity and relatively coordinated proportion.The two methods of baking,steaming,heating and curing as well as 20~45 d storage period are conducive to better flavor and texture characteristics of mini sweet potato.The root system in early growth stage contains high activity of sucrose decomposition enzyme,especially high invertase activity,which is an important reason for the early maturity,high quality and high number of tubers of’Xinxiang’,and the sweetpotato harvested during the 80~100 d growth period has better nutrition and taste quality.The advantages of high quality of’Xinxiang’can be inherited well by the offspring varieties.The application of novel cropping systems and breeding utilization of mini-type sweet potato should be strengthened by taking advantage of the early-maturing and high quality characteristics of’Xinxiang’.
