[Abstract]
Zhongliang 32 is a new cultivar of winter wheat bred systematically by crossing with the parental combination of Xinkang 12/Zhong 04304. In 2013—2015, the average yield of Zhongliang 32 is 6 944.25 kg/hm2 and 6.8% higher than that of the control Lantian 19 in winter wheat regional test in Longnan district. In 2015—2016, the average yield of is 5 568.00 kg/hm2 and 4.0% higher than that of the control Lantian 19 in 5 place in mountain winter wheat production test in Longnan district. The plant highth is 104.6 cm, ear length is 8.4 cm, thousand grain weight is 42.7 g, bulk weight is 802.00 g/L, crude protein content is 135.7 g/kg, settlement index is 35.00 mL, Wet gluten content is 25.1%. By inoculation identification, the result shows that Zhongliang 32 is middle resistance to mixture race of stripe rust at seeding stage, immune completely to CY 33, CY 34, Gui 22-24 and other mixture race pathogen at the adult stage. It is suitable to grown in the Tianshui mountain area, the arid mountains and the semi arid areas with the higher fertility surrounding areas below the elevation of 1 800 m, and the semi-arid mountain region of the north and south and.
