摘要
为全面评价不同类型甘薯品种品质育种指标以及提高育种效率,以2005-2016年育成的13个浙薯系列鲜食及食品加工型甘薯品种为材料,分析亲本系谱,统计品种特征特性,并依据品种用途、干率等对其主要品质性状进行分组比较。结果表明,浙薯系列甘薯品种系谱来源主要是胜利百号和南瑞苕衍生品种栗子香血缘。浙薯81及其衍生品种浙薯13在作为骨干亲本时表现出理想的育种效果。从品种的特征特性来看,鲜食型品种(包括迷你型鲜食品种)具有相对较高的干率(>30%)和淀粉率(>20%);不同类型品种生薯、熟薯的糖分(可溶性糖、还原糖)含量因品种而异;不同加工用途品种类型对胡萝卜素含量指标要求不同。不同类型品种的品质育种指标应进行综合评价,鲜食型甘薯主要以食用品质指标为主,干率是重要的品质指标之一;食品加工型甘薯主要以加工适应性目标为主,需注重中高干率、中高胡萝卜素含量、糖化快等材料的筛选与利用。本研究结果为优质鲜食及加工型甘薯新品种选育的种质创新和应用提供了理论参考。
To comprehensively evaluate the index of quality breeding and improve the breeding efficiency of different sweetpotato varieties,13 Zheshu sweetpotato varieties developed for table use and food processing in 2005-2016 were used as materials.Pedigree and characteristics of these varieties were analyzed,and the main quality traits of these varieties were compared by groups based on uses and dry matter contents.The pedigree results showed that Zheshu sweetpotato varieties were mainly originated from Okinawa No.100 and Nancy Hall.Zheshu 81 and Zheshu 13 showed ideal breeding effects when used as backbone parents.From the characteristics of varieties,the varieties for table use(including mini-type varieties for table use)had relatively high dry matter rates(>30%)and starch rates(>20%).The sugar contents(soluble sugar and reducing sugar)of raw and cooked sweetpotato varied from variety to variety.Different carotene contents were required for different types of sweetpotato varieties.Comprehensive evaluation of the quality traits for different types of varieties is required,edible quality was the main index,and dry matter rate is an important index of quality.Sweetpotato varieties for food processing are mainly evaluated based on the adaptability of processing,screening and utilization of breeding materials with high dry matter rate,medium and high carotene content,and fast saccharification should be emphasized.This study provides references for germplasm innovation and application of sweetpotato varieties with high quality for table use and food processing use.
