该品种是辽宁省农业科学院玉米研究所选育成功的玉米杂交种,2004年7月通过国家农作物品种审定委员会审定。品种审定编号:国审玉2004003。该品种为早熟杂交种,在沈阳地区春播生育期120d,适宜种植区域为黑龙江南部、吉林中北部、辽宁东部山区、内蒙古大部分地区、关内夏播区及陕西、山西等。由于地力、气候及管理等各种原因,该品种的繁育基地主要分布在甘肃、宁夏及内蒙古西部等西北地区。随着该品种在适宜地区种植面积的不断加大,其制种面积也相应增加,为了保证制种单位及农户的利益,笔者在几年对该品种制种工作中总结了一些基本工作经验,现就该品种制种过程中应注意的几个问题总结如下,供该品种及相似品种在西北区域制种做参考。
The breed is a corn hybrid that was successfully bred by the Institute of Maize, Liaoning Academy of Agricultural Sciences. In July 2004, it was approved by the National Crop Variety Approval Committee. Variety approval number: jury jade 2004003. The variety is a precocious hybrid. In the spring sowing period of 120 days in Shenyang, the suitable planting areas are southern Heilongjiang, central and northern Jilin, mountainous area in the east of Liaoning, most of Inner Mongolia, sowing area in summer and Shaanxi and Shanxi. Due to various reasons, such as geography, climate and management, the breed bases of the breeds are mainly distributed in the northwestern regions such as Gansu, Ningxia and Inner Mongolia. With the continuous increase of planting area in the suitable area, the seed production area increased correspondingly. In order to ensure the benefit of seed production units and farmers, the author summed up some basic work experiences in the seed production of the variety in recent years, At present, several problems that should be paid attention to in the process of seed production are summarized as follows, for reference of seed production of this variety and similar varieties in Northwest China.
