玉米新品种辽单266选育技术研究

Study on Breeding Technology of New Maize Variety Liaodan 266

为了丰富辽宁省玉米中晚熟区优良品种,辽宁省农业科学院玉米研究所采用单倍体技术、分子标记辅助选择技术、早世代配合力测定等方法选育玉米自交系,组配适宜辽宁省中晚熟区种植的玉米新品种辽单266,于2021年通过辽宁省农作物品种审定委员会审定。

In order to enrich the fine varieties of maize in the mid-to-late maturity areas of Liaoning province,the Maize Research Institute of Liaoning Academy of Agricultural Sciences used haploid technology,molecular marker-assisted selection technology,and early generation combining ability determination methods to select maize inbred lines.The new maize variety Liaodan 266,which was suitable for planting in the mid-to-late maize areas of Liaoning province,was approved by the Crop Variety Approval Committee of Liaoning Province in 2021.
