摘要
运用随机区组设计,研究了7个杂交玉米新品种产量情况。结果表明,产量由高到低的顺序为黔单16>桌玉818>正大999>禾玉36>渝单8号>中单808>贵单8号。其中黔单16的产量达到了9 765.9 kg/hm^2,产量最低的品种贵单8号为7 845.15 kg/hm^2。方差分析结果表明,黔单16、桌玉818这2个品种间差异不显著,而这2个品种与其他5个品种均达到了极显著水平。综合考虑,黔单16、桌玉818这2个品种更适宜本地区种植。
The yield of seven new hybrid maize varieties was studied by random block design. The results showed that the order of yield was Qiandan 16〉Zhuoyu 818〉Zhengda 999〉Heyu 36〉Yudan 8〉Zhongdan 808〉Guidan 8. Among them,Qiandan 16 production reached 9 765.9 kg/hm2, the variety with lowest yield was Guidan 8（7 845.15 kg/hm2 ）.The results of variance analysis showed that there was no significant difference between Qiandan 16 and Zhuoyu 818,and there was extremely significant difference between these two varieties and the other five varieties. Comprehensive consideration, Qiandan 16 and Zhuoyu 818 are more suitable for planting in the region.
