摘　　要：在慈利县按随机区组试验设计,安排平展型玉米(临奥1号、正大999、三北89以及对照品种)和紧凑型玉米(洛玉1号)等5个常规玉米品种进行比较试验,对各品种进行苗情观察和考种。结果表明:洛玉1号的生育期最短,为125 d,正大999生育期为137 d,三北89生育期为136 d,临奥1号生育期为135 d,对照品种的生育期为131 d;平均产量的排序为洛玉1号>三北89>临奥1号>正大999>对照品种,洛玉1号的平均产量最大,为597.3 kg/667m^2;光合势排序为正大999>洛玉1号>三北89>临奥1号>对照品种;各品种的成熟天数基本为50 d;三北89抗性综合最好,其他品种抗性较好。由此可知紧凑型玉米洛玉1号适宜在慈利县推广,平展型玉米的发展趋势应为抗性好、品质好的硬粒性品种。According to the experimental design of the random district group in Cili County, fve conventional corn varieties, such as fat type maize Linao No.1, Zhengda 999, Sanbei 89 and control variety, and compact type maize Luoyu No.1, were arranged for comparison test, and seedling observation and seed examination were conducted for each variety. The results showed that the growth period of Luoyu No.1 was the shortest, 125 days, Zhengda 999 was 137 days, Sanbei 89 was 136 days, Lin’ao No.1 was 135 days, and the growth period of the control variety was 131 days. The order of the average yield was Luoyu No.1 〉 three north 89 〉 Lin’ao No.1 〉 Zhengda 999 〉 control variety, the average yield of Luoyu No.1 was the maximum, which was 8959.5kg/hm^2. Photosynthetic potential sequencing was the control variety of Zhengda 999〉Luoyu No.1〉Sanbei 89〉Lin’ao No.1〉control variety. The maturity days of each variety were 50 days. Sanbei 89’s resistance comprehensive was the best, and others were good. Therefore, the compact type maize Luoyu 1 is suitable for promotion in Cili County, and the development trend of fat corn should be hard grain varieties with good resistance and quality.
