Abstract: According to nitrogen and phosphorus contents in grain, leaf and stem of wheat parent materials, 133 wheat parent materials were divided into nitrogen high-efficient parents, low-ability parents in absorbing nitrogen and nitrogen low-efficient parents and team were also divided into phosphorus low-efficient parents, phosphorus-wasted parents and phosphorus high-efficient parents, cluster analysis was adopted in the paper. There were 7 wheat parent materials whose nitrogen and phosphorus utilization efficiency were higher. Variance analysis showed that their was more variable among classes than in class for organs. By F-test, difference of nitrogen contents in grain, leaf and stem were significant for parent classes that nitrogen utilization efficiency was different. And difference of phosphorus contents in grain and leaf were significant for parent classes that phosphorus utilization efficiency was different. But differences of phosphorus contents in stem were not significant for parent classes that phosphorus utilization efficiency was different.
