通过对5个国审京冬系列小麦品种京冬12、京冬17、京冬18、京冬22和京花9号在北部冬麦区区域试验中的表现,对其进行农艺和品质性状分析.结果表明：京冬系列品种中早熟,株型紧凑,灌浆进程快,后期叶片功能期长,产量三因素比较协调,综合丰产稳产性及抗性较好.其育种思路是根据北京地区小麦穗分化和灌浆期短的气候生态特点,明确＂以粒大为特点,以穗粒质量为优势,同时兼顾产量三因素协调发展＂的中间型育种模式,通过高代品系的多点种植,注重选择综合的农艺性状和抗性.

The aims of this paper were to analyze the agronomic and quality traits of five national approved wheat varieties Jingdong 12, Jingdong 17, Jingdong 18, Jingdong 22 and Jinghua 9 based on their performance in the regional yield potential trials in northern winter wheat zone. The results indicated that the Jingdong series of winter wheat varieties had early to medium maturity, compact plant type, fast grain filling rate, long duration of leaf function at later stage, superior yield components, high yield and stability, and good tolerance to biotic and abiotic stresses. In consideration of the ecological climatic characteristics in Beijing, where wheat has a short time of spike differentiation and grain filling, our breeding strategies were to select a intermediate type wheat varieties with high kernel weight, high spike weight and an ideal development of three yield components; we paid attention to the selection of integrated agronomic traits and tolerance to biotic and abiotic stresses using multiple-location field trials. This will provide useful information for breeders and application of these wheat varieties.
