在17个试验点上研究了99个玉米新品种的丰产性和稳产性以及各试验点对品种的综合测试能力。结果表明,郑单958、先玉335、沈2152、M56/S121、06广14和浚07-6等品种具有较好的丰产性和稳产性,适合在某些特定区域推广;陕西杨凌、河南新郑、山东济宁和高密等试验点具有较好的年内品种判别能力和年际间的稳定性。研究结果为指导玉米优良品种在适宜区域推广具有一定的指导意义。
The yield and stability of 99 new maize cultivars were studied at 17 test sites and the comprehensive testing ability of each test spot on the varieties. The results showed that varieties such as Zhengdan 958, Xiangyu 335, Shen 2152, M56 / S121, 06 Guang 14 and Jun 07-6 had good yield and stability, and were suitable for popularization in some specific regions. Yangling, Shaanxi Xinzheng, Shandong Jining and Gaomi and other test sites have better year breed discrimination ability and interannual stability. The research results have certain guiding significance for guiding the popularization of fine varieties of corn in the appropriate area.
