山西冷凉区旱地鲜食玉米品种筛选
Selection of Fresh Maize Cultivars for Dryland in Cold Areas of Shanxi
摘要
Abstract
In order to select the high yield and high quality fresh maize cultivars suitable for planting in dryland of cold areas in Shanxi,in this study,the field experiment was carried out using 8 fresh maize cultivars(4 sweet and 4 waxy)as experimental materials.The agronomic traits,yield,grain nutrition,and water use efficiency(WUE)of each cultivar were analyzed and compared.The results showed that the fresh ear yield of Meiyu 27 and Wannuo 2000 were higher than that of the other,which were 22 469.1 kg/ha,20 665.7 kg/ha,respectively.The WUE of Meiyu 27 and Wanuo 2000 was 58.8%and 47.5%higher than that of the 4 fresh sweet maize cultivars of Huanaitianyu 23,Taiyanghua 8,Shenketian 4,and Taixiantian 2.Although the yield of Huanaitianyu 23 was lower than that of Meiyu 27,Wannuo 2000,the grain nutrition was higher than that of the fresh waxy maize,and the WUE was higher than that of the other 3 fresh sweet maize cultivars.At the same time,the principal component analysis method was employed to combine the yield,grain nutrition content,and WUE into 3 independent principal components whose cumulative contribution rate was 96.61%.Subsequently,the membership function value of the 3 independent principal components was comprehensively evaluated using membership function,the results showed that the D value of Meiyu 27 and Wannuo 2000 ranked the top two in the fresh waxy maize cultivars and the D value of Huanaitianyu 23 and Taiyanghua 8 ranked the top two in the fresh sweet maize cultivars,respectively.But the growth period of Taiyanghua 8 was longer,its yield and WUE were lower.In conclusion,Meiyu 27,Wannuo 2000,and Huanaitianyu 23 could be used as fresh maize cultivars for dryland of cold areas.关键词
