| Abstract: | Zhuanglang 12 is a newly bred winter wheat cultivar by perental combination of inbred line 92-18 with Handasui by Zhuanglang Agro-Tech Extension Center with the pedigree method . The result shows that the average yield of Zhuanglang 12 is 4 372.35 kg/hm2 which is 7.09% higher than that of the check Longzhong 1 in regional trial of Gansu province winter wheat in the period 2011 to 2013 . In 2013—2014,the average yield is 4 861.65 kg/hm2,which is 15.3% higher than that of the check Longzhong 1 in production test of Gansu province . Zhuanglang 12 is a Cultivar of strong winter wheat-late maturing . The growing period is about 272~285 days . The plant height is about 90~120 cm,The effective per plant is 3~5,ears humber is 4.56 million to 7.89 million/hm2,overwintering percentage is 94%,ear length is 6.5~8.2 cm,spikelets per spike is 15~18,grain number perspike is 32.5~52.0,thousand grain weight is 35.0~48.0 g,bulk density is 763.8 g/L. In addition,protein of seeds is 128.2 g/kg (dw),wet gluten is 250.7 g/kg (14%moisture),the lysine is 3.77 g/kg (dw),the settling value is 30.5 ml (14% moisture). It is immune to stripe rust on the main popular stripe rust which Gui22-14,Gui22-9,Shui 4,CY 33 and CY 32. The drought resistance and adaptability of Zhuanglang 12 is very strong. It is suitable to be grown in the 2 600 m altitude arid and semi-arid region with precipitation is 200~500 mm of Gansu. |
