| Abstract: | Reid inbred lines of maize have the advantages of high combining ability, high yield of self, good commodity quality, good seed early-onset and suitable for precise sowing, but the disadvantage is that they are not resistant to northern leaf blight of maize. Hybridization with the inbred line 33D22 which have Reid germplasm and high resistance to northern leaf blight of maize was selected as the basic material of selection. Inbred lines JiD284 and JiD2417 with resistance to northern leaf blight of maize, high yield, high quality, and high combining ability were developed by large population, high density, and artificial inoculation. They were used as parents to develop new maize varieties Jidan616 and Jidan626, which were approved by Jilin province in 2021. |
