摘要

2016-2018年,对保加利亚黄金西部种子有限公司育种公司的有前途的玉米品系(FAO 290-399)进行了评估,这些品系含有超过50%的碘多杂种群体和6个测试者,主要是兰开斯特群体。结果表明,GW59024和GWC06021(碘杂种群)最适合作为抗旱集约化杂交种的循环亲本。在兰开斯特杂种优势群体的测试中,最有趣的是GW59008和GW57010,在玉米发育有利年份,GW59008和GW57010的一般配合力都非常高。关键词:玉米;单系和杂交种;粮食产量的配合力

Research of combining ability of mid-early maize lines
In 2016–2018, the promising maize lines (FAO 290–399) of the Golden West Seed Bulgaria Ltd. breeding company, containing more than 50 % of the plasm of the Iodent heterotic group and 6 testers, mainly of the Lancaster group, were evaluated. It was established that the lines GW59024 and GWC06021 (Iodent heterotic group) are the most suitable as recurrent parents in new breeding programs for intensive and drought tolerant hybrids. Among the testers of the Lancaster heterotic group, the most interesting were GW59008, which showed the highest general combining ability in favorable years for maize development, and GW57010, which had a very high general combining ability in all three years of research. Keywords: maize; lines and hybrids; combining ability on grain yield
