The certificated varieties were divided into two derivative systems Hualian and Daqingmiao, by analizing their genealogy. Hualian’s offsprings have plaid an important role in the crop production. Resistance between varieties of the two derivative systems to millet blast was very different. However, hey were neither A57-resistant nor F1-resistant. There was a very consistent relationship between disease-resistances of developed varieties and their parents. The result primarily show that Hualian’s disease-resistance should be improved by utilizing its adaptibity, while resistant source to A57 and F1 blast should be introduced in the future breeding project.
