摘　　要：对初步证明有应用前景的新苗头组合进行区域内多年多点鉴定试验,在丰产性、稳产性和区域适应性方面综合评价有应用前景的新杂交种。本研究于2016—2018年以黄淮南部地区种植的7个品种组合在6个试验地点产量结果进行分析,结果表明:参试品种产量的环境效应和基因型×环境互作效应均存在极显著差异。从参试地点看出‘苏试51417’丰产性和稳产性综合评价很好;‘金大丰1906’和‘苏玉41’稳产性很好,丰产性较好,综合评价良好,相对具有较大的推广应用空间,适合江苏省春夏播区域种植。Multi-year and multi-location variety tests are conducted on new maize varieties of preliminary promising applications so that their yield potential,stability and adaption can be evaluated.With 7 maize varieties in southern Huanghuaihai area,the screening experiments were carried out in 6 different typical ecotype locations from 2016 to 2018.The results showed that the effects of environment and genotype×environment on yield were significant.The comprehensive evaluation showed that the variety‘Sushi51417’had high and stable yield;the variety‘Suyu41’and‘Jindafeng1906’had stable yield and better field performance.These varieties could be extensively applied to maize production in Jiangsu Province.
