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 performance of five national trial Beijing Jingdong series wheat cultivars Jingdong 12, Jingdong 17, Jingdong 18, Jingdong 22 and Jinghua 9 in the winter wheat field test in the north was analyzed and their agronomic and quality characters were analyzed The results showed that: The varieties of Jingdong were premature, compact in plant type, fast in filling process, long in late leaf function and coordinated in three factors of yield, Differentiation and short filling climate and ecological characteristics of a clear “grain size is characterized by the grain quality as a preponderance, taking into account the coordinated development of three factors yield” mode of breeding, through the high generation lines of multi-point planting, Focus on selecting agronomic traits and resistance.
