Phosphorus is the inorganic nutrients required by wheat for growth and development. The effective phosphorus in soils is lack, and application of available phosphor into soil is one of efficient routes to increase wheat grain yield. But phosphorus which are non-mobile in the soil profile, subjects to fixation reactions that render them unavailable. And it attributes the low phosphorus utilization rate. Screening wheat cultivars with P-efficient genetic characters, it is of great significance to improve the ...
