【摘要】 对 1999～ 2 0 0 0年广东省超甜玉米新组合区域试验资料的分析结果表明 :近年我省选育的超甜玉米新组合鲜苞单产水平有较大提高 ,抗病性与适应性较强 ,但品质的改良进展较缓慢 ;要选育优质、高产和多抗的超甜玉米新品种 ,在不断引进国外优异品种资源的同时 ,应加强种质创新研究 ,以拓宽育种亲本的遗传基础 ;利用现代生物技术与传统育种技术有机结合 ,加快品质育种进程 ,培育出具有突破性的优良品种是当务之急更多还原

【Abstract】 Analysis and evaluation on fresh ear yield, quality characters, agronomic traits and resistance to diseases of 12 supersweet maize new hybrid combinations from Guangdong provincial regional trials of supersweet maize varieties during 1999～2000, which were conducted in the present time The results showed that these new hybrid combinations have higher fresh ear yield and a better resistance to diseases ,and were bred in recent years However, the advancement on the quality improvement of supersweet maize was still slower The introduction of new elite varieties resources, organic combination of biotechnology breeding and conventional breeding methods, which should be carried out in the present time, in order to breed some good hybrid combinations with top-quality, high-yielding and multi-resistances更多还原
