【摘要】 通过对2005—2008年黄淮海地区糯玉米区试结果的分析,从参试品种的品质、产量和抗病虫害能力方面,探讨糯玉米研究的进展、存在的问题及发展对策。参试糯玉米品种品质评分达到一级标准的很少,而且决定糯玉米品质的关键糯性指标的分值并不突出;多数参试品种的鲜穗产量处于10501～13500kg/hm2,未能突破15000kg/hm2;参试品种粗缩病和黑粉病的感病率有明显增高的趋势。黄淮海地区糯玉米育种,应主要关注糯性指标、鲜穗产量、抗玉米粗缩病及黑粉病能力的提高。更多还原

【Abstract】 The result of Huanghuaihai waxy maize regional trials was analyzed from 2005 to 2008.It included seed quality,ear yield and diseases resistance of testing varieties.The progress,problems and developmental policies of waxy maize research were discussed or proposed.Yield evaluation showed that the amount of waxy corn varieties qualified for primary satandard was too less.The ear yield was between 10501-13500 kg/hm 2,all less than 15000 kg/hm 2.The tendency of waxy corn varieties infected by maize rough dwarf virus or smut was increasing.The waxy corn breeding in Huanghuaihai region should pay attention to waxy index,ear yield,resistance against maize rough dwarf virus or smut.更多还原
