摘要
本研究目的是全面了解和比较小麦新品种京花9号的特征特性与生产利用价值。以2005～2007年国家区试和北京区试结果为依据,对京花9号的特征特性和产量结构进行了分析。结果表明:京花9号产量三因素协调,具有较好的丰产、稳产和适应性。其平均产量在参试的64个品种48个点次试验中位居前列,在国家区试和生产试验中平均较京冬8号增产5.09%,差异达显著水平,表现出了突出的稳产性和适应性。
The aim of this study was to thoroughly investigate the characteristics of Jinghua No. 9 and its value in wheat production. The characteristics and yield components of Jinghua No. 9 were analyzed based on the results from national wheat yield potential trial and Beijing wheat yield potential trial from 2005 to 2007. The results indicated that Jinghua No. 9 with the characteristics of high yield, good stability and adaptability, and it had harmonious three yield components. The average yield of Jinghua No. 9 was on the top rank among 64 varieties in the field trials of 48 sites, it was increased by 5.09% in the national yield potential trial and production trial compared with the control variety Jingdong No. 8, and the difference reached significant level, the outstanding stability and adaptability were showed.
