摘要
我国甜玉米育种起步较晚,与国外水平相比,我国甜玉米产业发展还存在品种类型单一、品质差、加工专用型品种缺乏等问题。针对甜玉米尤其是水果型甜玉米生产及市场发展中的问题,近十年通过引进200多份国外和国内优良种质资源,并进行种质创新和优化杂优模式,按照"高、大、严"选系原则,选育出20余个骨干自交系;组配选育出京科甜115、京科甜116、京科甜183、京科甜158、京科甜2000、京科甜168、京科甜189等京科甜系列水果型玉米品种,口感甜脆、商品性明显提高,同时具有抗性强、产量高的特点。京科甜系列品种已分别通过国家和省级农作物品种审定委员会审定,在我国华北和东北地区得到大面积推广应用。
Compared with other countries, the development of national sweet corn industry, which started late, still had some deficiencies, such as lacking of variety type, poor quality, and processing-type deficiency. Based on the production and market situation of sweet corn, especially the fruit type, we introduced more than 200 germplasms home and abroad, which were innovated and applied about heterotic pattern. Seven sweet corn varieties, Jingke- tian126, Jingketian115, Jingketian116, Jingketian183, Jingketian158, Jingketian2000, Jingketian189, which had a higher quality, high yield, and strong resistant, were developed. So far varieties of Jingke series innovated heterotic pattern of national sweet corn breeding, had been authorized by national or province crop variety approval commit- tee, and they were widely planted in the northern part of our country.
