特用糯玉米新品种组合的选育与栽培技术研究

目的]介绍特用糯玉米(Zea mays L.)新品种组合的选育方法及高产栽培技术。方法]从全国各地引入144个特用糯玉米品种资源,在北京农业职业学院实训园进行种植。在生育期间进行物候期观察及地区适应性鉴定,淘汰地区适应性差的品种,选择适应北京地区的品种。结果]根据北京地区目前糯玉米育种目标,提出了糯玉米选育的要求,生育期为85～90 d,适口性好,鲜穗产量为1.35万kg/hm2以上,抗病虫糯玉米品种。经多年选育出N26-11×N24-10组合。同时对糯玉米种植密度、施肥、除草剂等关键栽培技术进行研究。结论]该研究可为特用糯玉米育种与生产提供参考。

Study on Breeding and Cultivation Techniques of New Combinations of Special Waxy Maize(Zea mays L.) Varieties

Objective] The aim was to introduce the breeding method and cultivation techniques of new combinations of special waxy maize varieties.Method] 144 special waxy maize varieties from all over the country were introduced and planted in agriculture training park of Beijing Vocational College.By phenophases's monitoring on their growing season and regions adaption's identifying,that the adapting varieties in beijing area were selected and the area poor adaptability were out.Result] According to the Beijing area in waxy maize breeding goals nowdays,the requirements of Waxy Maize Breeding were put forward,the N26-11 ×N24-10 combining variety was bred in past many years,which has 85-90 d growth season,good palatability,above 1.35×104 kg/hm2 yield of fresh ear,resistant to insect pests.At the same time,the key cultivation techniques of waxy maize planting density,fertilizer,herbicides were studied.Conclusion] The study provides a reference for the special waxy maize breeding and production.
