通过6个紧凑型玉米组合的比较试验，结果表明：以临奥4号和登海3638最好，产量分别为545.68kg／667m^2和542．47kg／667m^2，比对照毕单10号分别增产46．6％和45．7％；且两品种各种性状表现较好，抗逆性较强，适宜在毕节地区进行示范种植；成单30、奥玉3102、云杂一号比对照分别增产44.2%、43.8%、43.8%、38.9%，与临奥4号和登海3638间差异不显著，抗逆性强，可续试一年，奥玉17各方面表现的较差，抗逆性较弱，可淘汰。

Comparison of the New Combinations for Compact-typed Maize

It revealed, through six compact-typed maize experiments, that Lin-ao 4 and Denghai 3638 were the best of all with output respectively for 545.68kg/667m^2 and 542.47kg/667m^2 , increased by 46.6% and 45.7% than Bidan 10. They were good in basical characters and suitable for demonstrative cultivation in Beijie Prefecture. Chendan 30, Aoyu 3102, and Yunzha 1 increased by 44.2 %, 43.8%, and 38.9% higher than Bidan 10 respectively but there were no significant difference with Lin-ao 4 and Denghai 3638. Therefore it is suggested that they should be tested next year. Aoyu 17 can be eliminated due to its bad outcome.
