[Abstract]
To improve wheat yield and quality and to ensure food security and sustainable development of grain industry, hybridized combinations with new lines Jiu 9194 as female parent(bred by Jiuquan Academy of Agricultural Sciences) and 9913-17 as male parent(bred by Gansu Academy of Agricultural Sciences) were made. Through 5 a successive individual selection, traits of this new line were stable in 2015. Data from regional trial of Gansu Province(irrigated land, western zone) carried out in 2018 and 2019 showed that average yield from 12 sites in 2 a was 7 870.5 kg/ha, which was 4.24% higher compared with that of the control Ningchun 4. Data from production trial of Gansu Province (irrigated land, west ernzone) carried out in 2020 showed that average yield from 6 sites was 8 339.3 kg/ha, which was 8.03% higher compared with that of the control Ninchun 4. Growth period is 103 d and plant height is 90.0 cm. It is a compact plant type with evenlyspikes layer. The spike number, grain number per spike, 1000-seed weight and volume weight are 6 492 000/ha, 41.06, 46.3 g and 787.4 g/L, respectively. This new variety with premium charactersis is moderately resistant to powdery mildew disease, moderately susceptible tostrip rust disease, and is suitable for irrigated land in Hexi Corridor region of Gansu Province.
