| Abstract: | The new winter wheat variety 7230 was crossed with female of 919-18/5 and male of Mianyang 87-31 following pedigree selection, and bred by Lintao Agricultural School of Dingxi city of Gansu. The variety was 90 to 105 cm high in plant height, 6 to 12 cm long in ear length,2 to 5 seeds per spikelet,40 to 60 grain and 1.6 to 2.4 g per ear,34.8 to 54.1 g in TGW,138.6 g/kg in gross protein,0.45% of lysine,294 g/kg of wet gluten,and 29.0 ml of sedimentation value.In ecological trials of 2 000 through 2002,the yield averaged 5 820.2 to 8 783.4 kg/hm~2,which was 18.4% to 83.0% higher than that of Linnong 157.It performed good cold tolerance, and high drought and strip rust resistance.It is adaptive for areas along middle-lower reaches of Taohe river,Weihe watershed, and irrigated and high altitude and cold areas of some counties in Qinghai province. |
