Comparative experiment on display of summer maize varieties in Northwest Anhui Province

为筛选适宜皖西北地区栽培的夏玉米新品种,本研究以东单6531、丰大611、华安玉2号、东单1971、华安玉5号和东单905等106个玉米品种为试验材料开展试验,其中东单6531和丰大611等33个品种以60000株/hm^(2)栽植,华安玉2号和东单1971等56个品种以75000株/hm^(2)栽植,华安玉5号和东单905等17个品种以90000株/hm^(2)栽植,对各品种产量及产量构成因素以及试验区的气象资料进行对比分析。结果表明,60000株/hm^(2)密度组优秀品种7个(丰大611、丰德存玉13、荃科玉900、京农科767、瑞华玉3号、瑞华玉288和谷神玉6号);75000株/hm^(2)密度组优秀品种15个(丰大602、侬玉662、荃科789、富玉188、烟玉604、硕秋702、ZY806、康农玉889、明天695、明天636V2、先玉1773、登海1717、航研9013、K1998和迪卡653);90000株/hm^(2)密度组优秀品种5个(硕玉551、TH3366、中垦玉561、京农玉658和鲁研106)。以上品种可在研究区进行进一步的示范种植。

In order to select new summer maize varieties suitable for cultivation in Northwest Anhui Province,106 maize varieties including Dongdan 6531,Fengda 611,Hua’anyu No.2,Dongdan 1971,Hua’anyu No.5 and Dongdan 905 were used as experimental materials,among which 33 varieties such as Dongdan 6531 and Hefengda 611 were planted at 60000 plants/hm^(2),56 varieties such as Hua’anyu No.2 and Dongdan 1971 were planted at 75000 plants/hm^(2),and 17 varieties such as Hua’anyu No.5 and Dongdan 905 were planted at 90000 plants/hm^(2).The results showed that there were 7 excellent varieties in 60000 plants/hm^(2) density group(Fengda 611,Fengdecunyu 13,Quankeyu 900,Jing⁃nongke 767,Ruihuayu 3,Ruihuayu 288 and Gushenyu 6).15 excellent varieties(Fengda 602,Nongyu 662,Quanke 789,Fuyu 188,Yanyu 604,Shuoqiu 702,ZY806,Kangnongyu 889,Mingtian 695,Mingtian 636V2,Xianyu 1773,Denghai 1717,Hangyan 9013,K1998 and Dika 653)in the density group of 75000 plants/hm^(2);There were 5 excellent varieties in 90000 plants/hm^(2) density group(Shuoyu 551,TH3366,Zhongkenyu 561,Jingnongyu 658 and Luyan 106).The above varieties can be further planted for demonstration in the study area.
