摘要 ‘浚单658’是河南省鹤壁市农业科学院以自交系‘浚58’为母本、自交系‘浚G6Y62’为父本杂交育成的玉米单交种,于2020年通过国家审定、2021年通过河南省审定。多年多点试验结果表明,该品种具有抗逆性强、耐密、稳产、丰产性好、结实性好、品质佳、淀粉含量高、粮饲兼用等特点,是顺应黄淮海气候变化趋势的玉米新品种。本研究介绍了‘浚单658’的选育经过、品种特征特性、产量表现、生产应用,围绕其抗逆性、耐密性、稳产性等品种特点,重点讨论了其选育对抗性育种、选育过程、选育目标的启示,以期为新气候形势下黄淮海夏玉米品种选育提供模式参考。 The new maize variety ’Xundan 658’ was bred by Hebi Academy of Agricultural Sciences by using ’Xun 58’ as female parent and ’Xun G6Y62’ as male parent. In 2020, the variety was approved by the National Crop Variety Approval Committee, and in 2021, the variety was approved by Henan Provincial Crop Variety Approval Committee. The results of multi-year and multi-site tests showed that the new maize variety could adapt to the climate change trend of Huang-Huai-Hai plain and had the characteristics of strong stress resistance, high density tolerance, stable and high yield, good seed setting ability, superior quality and high starch content, and could be used for both grain and forage. As a whole, in order to provide a reference model for maize breeding in Huang-Huai-Hai plain under the new climate condition, the study expounded the breeding process, variety characteristics, yield performance and production application of ’Xundan 658’ . In addition, based on the variety’s characteristics of stress resistance, density tolerance and yield stability, the enlightenment on resistance breeding, selection process and breeding goal was discussed.
