Abstract: Multi-year and multi-location variety test need to be conducted for new corn varieties of preliminary promising applications so that their yield potential, stability and adaption can be evaluated. With 7 corn varieties in South of Huanghuaihai area, the screening experiments were carried out in 6 different typical ecotype locations in 2016-2018. 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 it had a better field performance. These varieties could be extensively applied for corn production in Jiangsu Province.
