As a special corn with the characteristics of both fruits and vegetables, the planting area of fresh corn in my country has expanded rapidly, and the market demand is strong. This study systematically evaluated several new varieties of fresh corn introduced in Linhai City, Zhejiang Province, and studied them from the aspects of biological traits, growth performance, agronomic traits, quality characteristics and regional adaptability. Regional trials and case studies showed that these new varieties showed good adaptability in Linhai City. Among them, varieties such as 'Caitiannuo 168' obtained a fresh ear yield of 900-1 200 kg per mu in Baishuiyang Town, which was significantly higher than the control variety; the new colorful sweet and glutinous varieties introduced in the coastal slightly saline-alkali land also achieved a fresh ear yield of more than 1 300 kg/mu, showing the advantage of salt tolerance. Based on the comprehensive trait evaluation and regional performance, excellent varieties such as 'Jinyin 208', 'Zhetian 19', 'Meiyu 25' and 'Caitiannuo 168' were selected for promotion in Linhai. This study also summarized the comprehensive performance of each variety, pointed out the current problems such as insufficient disease resistance, and put forward optimization suggestions for future introduction screening and efficient cultivation management, in order to provide a scientific basis for the renewal of fresh corn varieties and industrial development in Zhejiang coastal areas.
