| Abstract: | LK91 was a new maizeShybridcultivar bred by TongLiao Academy of Agricultural Sciences ,whose female parent was TX 11162and male parent was TX 06051.The average yield of LK91was 14388.8 kg/hm2 in yield trails forregional test in Inner Mongoliain 2016 and2017,which was 6.3% higher than the CK(Zhengdan 958).In the production test in 2018,the average yield of LK91 was 13396.5 kg/hm2,which was4.6% higher than the CK(Zhengdan 958).The variety has good properties such as high yield,resistanceto wide range and good quality,and which was examined and approved by Inner Mongolia Crop Variety Approval CommitteeIn 2019,and the authorized number was mengshenyu 2019063.In this paper,the breeding process of LK91 was elaborated,its characteristics andcultivation technologywereintroduced,so as to provide technical support for the popularization and application. |
