摘要:

针对南方薯区鲜食与淀粉加工兼用型甘薯品种缺乏、多抗优质品种不足的问题,为选育多抗兼用型甘薯新品种,以高产抗病广适的'福薯24号'为母本、优质食用型紫肉甘薯'榕紫2号'为父本进行人工有性杂交,经多年多点品比、区域试验与综合鉴定,选育出多抗兼用型甘薯新品种'福宁薯24号'。2017年、2019年两年福建省区试结果表明,该品种鲜薯平均产量31853.7 kg/hm2,比对照品种'广薯87'增产6.28%,薯干平均产量9288.75 kg/hm2,比对照增产3.90%,淀粉平均产量5614.05 kg/hm2,比对照增产5.25%。品种烘干率28.32%,食味评分80.4分,品质优良;抗蔓割病,中抗茎线虫病和根腐病,综合性状突出。2023年通过国家非主要农作物品种登记,2024年获品种权保护证书。综上所述,'福宁薯24号'具有丰产、稳产、食味品质优异等特征。本文系统介绍了'福宁薯24号'的选育过程、特征特性、品质、产量、抗病性分析表现及脱毒种苗繁育技术,为该品种在福建及相似生态区推广应用提供科学依据与技术支撑。

Abstract:

The aim is to breed a new dual-purpose type sweet potato variety with multi-resistance, and provide good variety support for the vigorous development of sweet potato industry in Fujian Province. 'Funingshu NO.24' is a new sweet potato variety with high yield, disease resistance and wide adaptability, which was bred by sexual hybridization of 'Fushu No.24' as female parent and 'Rongzi No.2'as male parent, and through years of multi-point comparison, regional testing, and comprehensive evaluation. The results of the regional tests in Fujian Province in 2017 and 2019 indicate that the average yield of fresh sweet potato was 31853.7 kg/hm2, 6.28% higher than that of the control 'Guangshu 87', the average yield of dried sweet potato was 9288.75 kg/hm2, 3.90% higher than that of the control, and the average yield of starch was 5614.05kg/hm2, 5.25% higher than that of the control. 'Funingshu NO.24' has the characteristics of high yield, stable yield, good eating quality, resistance to vine cutting disease, moderate resistance to stem nematode disease and root rot disease. In 2023, it passed the National Non-major Crop Variety Registration, and obtained the certificate of variety right protection in 2024. This paper mainly introduces the breeding process, characteristics, quality, yield, disease resistance analysis and virus-free seedling breeding technology of 'Funingshu NO.24', which provides a reference for the popularization and application of this variety.

Key words: 'Funingshu NO.24', sweet potato, breeding, dual-purpose type, fresh food, starch processing, virus-free seedling breeding
