SUI Jing-yue et al(Chaoyang Meteorological Bureau,Chaoyang,Liaoning 122000)  
[Objective]The research aimed to select new suitable millet cultivars in arid area of west Liaoning.[Method]Taking natural variant strains of Jinchuigu and Qifenggu as materials,the directional system breeding was made for continuous five generations.After preliminary examination,middle examination and popularization planting demonstration of cultivars,new millet cultivars with drought tolerance,lodging resistance,high yield and good quality were bred.[Result]The unit yield of Chaoxingu 2 and Chaoxingu 5 was 6 750.0-8 250.0 kg/hm2 and the highest yield was above 9 000.0 kg/hm2.The demands of two cultivars were as follows:≥10.0 ℃ accumulated temperature of 2 000-2 800 ℃,water requirement of 260-340 mm,sunshine time of 800-1 200 h.The large-grain millet had golden rice,fragrant smell,better taste,good appearance characters and commodity quality,resistance to drought,lodging,many diseases such as rust,mildew and smut.The cumulative popularization area of two cultivars in Liaoning Province during 2005-2007 reached 150 thousand hm2 and the popularization coverage in total millet area in this province during three years reached 42.3%.[Conclusion]The popularization application of Chaoxingu 2 and Chaoxingu 5 provided new approaches for making full use of regional climatic resources in semi-arid areas.
