| 中文摘要: |
| 广东是我国甘薯的优势区域，以种植生产、销售、消费优质食用鲜薯为主，是全国最大的鲜食型甘薯消费市场和集散地。近年广东甘薯种植面积基本稳定在15万hm2左右，居我国第4位。2006年以来广东甘薯品种改良取得较好进展，截至2019年底，国家种质广州甘薯圃保存甘薯资源1 981份；选育了33个甘薯品种通过国家品种鉴定或广东省品种审定，其中广薯87和普薯32为代表性品种，广泛种植于南方乃至全国薯区，为甘薯产业发展作出了巨大贡献。另外，在杂交不亲和性、航天诱变、病虫害抗性和分子生物学等育种技术方面均取得了很大发展。对2006年以来广东省在甘薯资源收集利用、育种技术、育种成效等方面工作进行了回顾和展望。 |
| 英文摘要: |
| Guangdong Province is one of the most predominant production regions of Chinese sweet potato（Ipomoea batatas）, in which high-quality edible fresh sweet potatoes have been mainly planted, produced, sold and consumed, and it is the country’s largest consumer market and distribution center for edible fresh sweet potato. In recent years, the cultivated area of sweet potato in Guangdong has been basically stable, with a statistical area of approximately 150 000 hm2, ranking fourth in the country. Considerable progress has been made in the improvement of sweet potato varieties in Guangdong since 2006. As of the end of 2019, 1981 sweet potato germplasm accessions has been preserved in the National Germplasm Nursery for Sweet potato（Guangzhou）; 33 selected sweet potato varieties have been examined and approved by the national variety verification or Guangdong variety identification, of which Guangshu 87 and Pushu 32 are two representative varieties, which have been widely planted in south China and even the whole country, and have made great contributions to the development of the sweet potato industry. In addition, rapid progress has also been made in breeding techniques including cross incompatibility, space mutation, disease and insect resistance, and sweet potato molecular biology. The previous work on the collection and utilization of sweet potato resources, breeding technologies and evaluation methods and breeding effectiveness since 2006 is reviewed, and prospect for future work is put forward. |
