不同玉米品种(系)在安宁河流域的适应性

Assessment of the Ecological Adaptability of Different Maize Varieties to the Areas Along Anlin River

通过29个玉米品种(系)对比试验,对各品种(系)产量水平、生育期、农艺性状、经济性状进行研究。结果表明:参试品种(系)产量高于对照雅玉998,综合性状表现较好,其中适宜于在安宁河流域种植的品种有奥玉28、SL011、资11、登海京稞968、德龙京稞968等,而其他品种因各种原因不适宜在攀西地区种植。

This study aimed to select maize varieties suitable for growing in the areas along Anlin River. A field trial was conducted in2017 in Xichang City, Sichuan Province to compare 29 maize varieties(or lines) with respect to yield, growth period, agronomic characters, economic characters, and resistance to diseases and pests. Results showed that five maize varieties attained higher yields than the control variety ’Yayu 998’, namely ’Ao-yu28’, ’SL011’, ’Zhi-11’, ’Denghaijingke 968’, and ’Delongjingke 968’, whose yields exceeded that of the control by 0.5%, 6.5%, 7.8%, 12.9%, and 15.3%, respectively. The five varieties also showed overall good characters;therefore, they are suitable for growing in the areas along Anlin River. By contrast, the other tested varieties are not suitable for planting in Panxi area due to their lower yields.
