Longjian 9343 was a new winter wheat variety， bred systematically by crossing with the parental combination Guinong 21/77-69 . The plant height 83~92 cm， ear length 7.9 cm， thousand grain weight 43.5 g， growing period 253 d， and seed crude protein 137.1 g/kg， Crude fat 18.6 g/kg， Lysine 4.3 g/kg， wet gluten 262 g/kg， sedimentation value 52.8 mL . The average yield of Longjian 9343 was 7 574.25 kg/hm2 and 10.52% higher than of the check Lantian 6 in Tianshui winter wheat regional test which was conduct during the period 2002 — 2004 in plain-waterland of Gansu provicev . By inoculating of Puccinia striiformis f . sp tritici， the results showed that it was immune to CY 29， CY 30， CY 31， CY 32， CY 33， Luo 13Ⅲ， Luo 13Ⅷ， Shui 4， Shui 7， HY 4， HY 7， HY 8 and mixture races at all-stage .
