摘要

In accordance with the sexual hybridization,a new cultivar Yugu 22 with high yield,good quali-ty and wide adaptabilty was bred by Anyang Academy of Agricultural Sciences by means of the pedigree method,and derived from the parental cultivars of Yugu No. 1 and Jigu 19. Yugu 22 was approved by Henan Crop Committee in April 2015 . The average yields of Yugu 22 were 5 187 . 7 kg/ha and 5 453 . 0 kg/ha at the millet cultivars regional test and production test of Henan in 2011—2012 and 2014,which increased by 12. 39% and 7. 18% compared with the control Yugu No. 9. The characteristics of the new variety was 1 000-kernel weight of 92. 83 g,crude protein of 9. 45%,fat of 2. 84%,coarse fibre of 0. 1% in millet,and height was 101 cm,the growth period was 95 d,which had the first grade resist-ance to millet rust,millet blast and lodging.
