摘要
近年来我国甘薯病毒病爆发,对产业发展造成严重影响,迫切需要建立全新的种薯繁育模式,为生产提供充足的健康种苗。本研究首次将“东种西繁”种薯繁育模式应用于甘薯,研究比较3个甘薯品种在西部高海拔冷凉地区和内陆地区两种生态环境下繁育脱毒种薯的质量差异,发现种薯带毒率与烟粉虱的发生呈显著正相关;相同基础苗繁育的种薯,内陆地区繁育的带毒率为17.41%~42.50%,西部冷凉地区繁育的带毒率为1.43%~8.72%,表明繁种环境是影响种薯质量的关键因素。“东种西繁”种薯繁育模式可显著提高种薯质量,推动我国甘薯种业的健康发展。
In recent years,the outbreak of sweet potato virus disease in China has severely affected the industry development of seed sweet potato,so establishing a new breeding mode to provide sufficient healthy seedlings for sweet potato production is urgent.In the study,the mode of root seeds of East breeding in West China was applied for the first time,and the quality differences of virus-free seed sweet potato bred with three sweet potato varieties under different ecological conditions of the western high-altitude and cold region and inland region were compared.It was found that the virus-carrying rate of sweet potato was significantly positively related to the Bemisia tabaci occurrence.The virus carrier rate of seed sweet potato was 17.41%~42.50% in inland area and 1.43%~8.72% in western cold areas under the condition of the same basic sweet potato seedlings,which showed that the breeding environment was the key factor affecting the seed sweet potato quality.We concluded that the mode of root seeds of East breeding in West China could significantly improve the quality of seed sweet potato and promote the healthy development of seed sweetpotato industry in China.
