摘要
为了筛选出适宜湘西北种植的杂交玉米新品种,以近年面积较大或新审定的21个杂交玉米新品种为试验材料,采用间比法分析各品种的丰产性、适应性和抗逆性。结果表明,参试品种的平均产量为8.08 t/hm2,筛选出产量超过对照(临奥1号)10%的品种有12个,其中,渝单19、科玉8号、中单808和湘康玉2号,产量高、综合性状优良,可适当推广种植。
In order to screen the new hybrid maize varieties suitable for planting in Northwestern Hunan, 21 new varieties of hybrid corns with large planting area or newly accreditation varieties in recent years were used as test materials. The yielding ability, adaptability and stress resistance of 21 new varieties was analyzed by the partition compares method designing. The results indicated that the average yield of the tested varieties amounted to per hectare of 8.08 tones. Twelve varieties had an increase of more than 10% over the contrast（Lin＇ao 1）. Amone the twelve varieties, Yudanl9, Keyu 8, Zhongdan 808 and Xiangkangyu 2 got high yield and good comprehensive characters,which could be appropriate to promote the cultivation.
