Abstract: In order to breed the new restorer lines and new varieties with drought-resistance, saline-resistance, extensively adaptability, strong adversity resistance, high yield and quality for planting in the?edible sunflower production regions of Shanxi, a field trial with excellent domestic variety resources and sterile lines was conducted to successfully breed the restorer lines of ‘Fenhui No.1’, ‘Fenhui No.2’ and ‘Fenhui No.3’ by using the bagging and selfing. The authors investigated the agronomic traits of the three restorer lines, identified their drought-resistance and saline-resistance, and selected the restoring and combining ability. The results showed that the three restorer lines had high combining ability, large numbers of pollen grains, 100% of restoring ability, drought-resistance, saline-resistance, high-resistance to verticillium wilt and sclerotinia sclerotiorum, and passed the acceptance tests on November 29, 2012 by Scientific Bureau of Shanxi Academy of Agricultural Sciences. ‘Fenhui No.1’had the best performance. The hybrid variety ‘Fk-0918’ was developed from the restorer line ‘Fenhui No.1’ and the average yield was 3726.56 kg/hm2, increased by 29.9% compared with the CK ‘YS809’ and ranked No.4 in area trials of edible sunflower in Shanxi Province in 2014. The variety ‘Fk-0918’ had disease-resistance, drought-resistance, saline-resistance, high yield, good commercial characteristics and the whole growth stage was 108 days which was suitable for planting in the edible sunflower production regions of Jinzhong and northwestern Shanxi. The application and popularizing prospect of ‘Fk-0918’was better.
