[Abstract]
Lantian 32 is a newly bred winter wheat variety by parental combination of Longyuan 031 with Lantian 16 . The average yield of Lantian 32 reaches 5 377.65 kg/hm2, which is 8.83% higher than that of the check Xifeng 27 in winter wheat regional test conducted in the period 2010 — 2012 in Longdong district. The result shows that the height is 62 ~ 74 cm, the number of grains per is 27.4 ~35.7, thousand kernet weight is 36.9 ~ 40.1 g, bulk density is 761 ~ 775 g/L . The result also indicates that the content of crude protein(dry basis), wet gluten(14% moisture), lysine and sedimentation value (14% moisture) are 185.9 g/kg, 313.1 g/kg, 5.2 g/kg and 51.2 mL, respectly . By inoculating identification of stripe rust, Lantian 32 is middle susceptible to mixture race at the seedling stage, but at the adult stage, it is immune to Shui 4, middle resistance to CY31, CY32, Gui22-9, Gui22-14 and mixture race, indicating of middle resistance to stripe rust . It is suitable to be grown in the valley area of South Qingyang district and in gully area of Northeast Pingliang district .
