摘要: 为客观全面地分析云南省玉米新品种的丰产性、稳定性及适应性,2019—2020年,在云南省12个区域试点对14个参试
玉米新品种进行了两年的随机区组试验。以海禾2号作为对照品种,采用方差分析、变异系数分析、适应度分析、C.S.lin和
AMMI等方法,对参试新品种的丰产性、稳定性及适应性进行了综合性分析。结果表明:2019—2020年的品种间、试点间、品种
与试点之间的互作达到了极显著水平;参试品种迪玉403、迪玉503、金粒66具有较好的丰产性和稳定性,是相对理想的品种;
宣威是最理想的试点,对品种选择性强,有利于选育出优良的玉米品种。本研究对云南省系列玉米新品种的生产性能进行了
评价,为推动云南省玉米产业的发展及高原特色农业的生态布局奠定了理论和实践基础。

Abstract: To objectively and comprehensively analyze the yielding ability, stability and adaptability of new maize varieties in Yunnan
province, a two-year randomized block experiment was conducted on 14 new maize varieties at 12 regional pilot sites in Yunnan
Province from 2019 to 2020. Haihe No.2 was used as the control variety. Variance analysis, coefficient of variation analysis, fitness
analysis, C.S.lin and AMMI methods were used to comprehensively analyze the yielding ability, stability and adaptability of the new
varieties. The results showed that the interaction among varieties, pilot sites, and between varieties and pilot sites reached a highly
significant level. The tested varieties Diyu 403, Diyu 503 and Jinli 66 are relatively ideal varieties with good yielding ability and
stability. Xuanwei is the most ideal pilot sites, with strong variety selectivity, which is conducive to breeding excellent maize varieties.
This study evaluated the production performance of a series of new maize varieties in Yunnan Province, laying a theoretical and
practical foundation for promoting the development of maize industry and the ecological layout of plateau characteristic agriculture in
Yunnan Province.

Key words: new maize varieties, yielding ability, stability, adaptability, Yunnan Province
