2010年河北省玉米联合鉴定试验结果与评价

Results and Evaluation of Combined Qualification Tests on Maize in Hebei Province in 2010

[目的]为河北省区域试验提供后备品系。[方法]以郑单958为对照,通过对河北省农业科研单位提供的92个优良玉米杂交组合进行田间观察和产量测定,鉴定出综合表现较好的优良品系。[结果]抗性较好的品系有F6813、HD264、W6139、CH53、石低1、资5、HD395、石低3和唐98601;产量较高的品系有HD395、HD264、石低3、资5、F6813、唐98601、CH53。[结论]优势品系为F6813、HD264、资5、HD395、石低3和唐98601,建议明年参加区域试验,其他品系继续观察。

[Objective] The aim was to provide reserve strains for regional tests in Hebei province.[Method] With Zhengdan958 as control,the field observation and yield determination of ninety-two maize hybrids provided by Hebei agricultural scientific research units were conducted to identify strains with good comprehensive performance.[Result] The strains with strong resistance were F6813,HD264,W6139,CH53,Shidi1,Zi5,HD395,ShiDi3 and Tang98601.The strains with higher yield were HD395,HD264,Shidi3,Zi5,F6813,Tang98601 and CH53.[Conclusion] The superiority strains supposed to be tried in the regional tests the next year were F6813,HD264,Zi5,HD395,ShiDi3 and Tang98601,and the rest should be kept under observation.
