【摘要】 结合山西地域、气候生态特点对50年来玉米生产状况和主要品种的种质基础及杂种优势模式进行分析,认为山西省玉米主要种质兼容于我国4大种质类群Reid、Lancaster、塘四平头和旅大红骨;主要杂种优势模式为Lancaster×塘四平头、Lancaster×旅大红骨、Reid×旅大红骨和Reid×塘四平头。山西独特的生态条件有利于玉米生产和良繁,但使玉米育种研究的自然选择压力严重不足,遗传基础狭窄,优良种质积累相当薄弱。今后要抓住机遇从玉米育种研究和种业开发上构建山西省玉米可持续发展综合战略模式,即:能力库(玉米育种研究网站)动力源[山西地域大型玉米良繁基地(集团)]效能1、效能2(普通玉米、专用玉米生产和良种供给)。促进山西玉米可持续跨越式发展。更多还原

【Abstract】 Due to the special ecological and geographical conditions,by analysing production,heterosis ex-ploitation and germplasm base of maize in Shanxi province during the past five decades,the predominant germplasm is involved in four heterotic groups,i.e.Reid,Lancaster,Tangsipingtou and Luda Red Cob,which are used widely in maize breeding;the heterotic patterns used are Lancaster×Tangsipingtou,Lancaster×Luda Red Cob,Reid×Luda Red Cob and Reid×Tangsipingtou.While the special ecological and geographical conditions benefit maize and seed pro-duction,and the environmental conditions are not satisfied for maize breeding.Whereas the germplasm base of maize in Shanxi is still narrow and still weak.We should take the chance to construct sustainable strategy of maize produc-tion about maize breeding and exploitation of seed sector to promote sustainable development of maize production in Shanxi:Technology storage(maize breeding net work)dynamic source(large-scale seed productiou in Shanxi province)Function1,function2(produce and process of common and special maize,and the supply of quality seeds).更多还原
