[Objective] This study aimed to meet the demand of farmers for highyielding, high-quality, wide-adaptability and multi-resistant new maize cultivars, and to make food production grow continuously. [Method] Comparative test of new maize cultivars was conducted at different altitudes in 2015, and the yield, main economic characters, agronomic traits, growth period and resistance of maize cultivars were analyzed. [Result] Ruidan 26 and Yongrui 16 can be cultivated in the areas below the altitude of 2 200 m; Huaxingdan 88 can be cultivated in the areas below the altitude of 1 750 m; the other new maize cultivars still need to be tested further. [Cenclusion] The research results can be applied in this area and other similar areas, which will effectively promote the upgrading of maize cultivars and improve the yield per unit area.
[Objective] This study aimed to promote the sustainable development of rape industry, and to meet the growing demand of urban and rural residents for vegetable oil. [Method] Field test was conducted for winter rape varieties in the national early maturing area in 2015, and their yield, main economic traits, growth period, consistency and stress resistance were evaluated comprehensively. [Result] Xiangyou 420, Qingza 12, Qianyouzao 3 and Yunyouza 16 could be applied in Baoshan City, Yunnan Province, and Yangguang 1418, Shengguang 127 and Qingza 10 （CK） should be further tested. [Conclusion] The results can be demonstratively applied in Baoshan City and other similar regions, so as to promote the development of rape industry.
