为筛选适应湘西自治州花垣县种植的玉米品种，于2013年在花垣进行了21个品种的比较试验。结果表明：（1）各品种产量在6750～11738 kg／hm2之间，宝玉007、正大999居前两位，分别为11738 kg／hm2和10926 kg／hm2，是花垣县玉米生产首选品种；（2）百农5号、三峡玉6号、高玉171、吉湘2188、高玉988、中玉335、源育16号、黔单988产量也在9500 kg／hm2以上，可适度示范推广；（3）品种间穗长、行粒数、穗粒数与产量呈极显著正相关，说明本试验条件下，大穗型品种产量潜力较高；（4）品种间灌浆期、百粒重与产量呈显著正相关，表明在不影响下茬作物的前提下，选择全生育期与灌浆期较长的品种，适期早播，提高百粒重，也是高产的重要保证。

To screen maize varieties suitable for planting in Huayuan county,Autonomous Prefecture of western Hunan,a comparative experiment was conducted in 2013 with 21 maize varieties as materials.The results showed that:(1)yield of all varieties was among 6 750 ~11 738 kg/hm2 ,and the highest two were Baoyu 007 and Zhengda 999,which were the op-timal varieties for planting in Huayuan county.(2)Yield of Bainong No.5,Sanxiayu No.6,Gaoyu 171,Jixiang 2188, Gaoyu 988,Zhongyu 335,Yuanyu No.16 and Qiandan 988 was above 9 500 kg/hm2 ,which was higher than that of Linao No.1 (CK)and worth to moderately demonstrated and popularized.(3)The correlation between yield and ear length, grain per row,gain per ear was very significant positive,respectively,which showed that yield potential of large -spike type variety was higher under conditions in this study.(4)The correlation between yield and filling stage,100 -grain weight was significant,which showed that selecting varieties with longer whole duration and filling stage and early sowing at an appropriate period to heighten 100 -grain weight was the important guarantee for high -yielding under the premise of not affect the late crop.
