ABSTRACT
Phosphorus (P) deficiency is a major yield-limiting constraint in wheat production. This situation is further aggravated by the depleting supply of P resources. The ability of wheat to adapt to low P soil is inferior to some wild grass species. In order to locate high P efficiency genes on specific chromosomes of wheat relatives, 107 wheat alien chromosome addition lines were used to investigate P efficiency at the seedling stage. The results showed that introgression of alien chromosomes affected the P uptake and utilization efficiency. which resulted in altered P efficiency. Nine addition lines conferred high P efficiency. seven addition lines conferred high P uptake efficiency, and 39 addition lines conferred high P utilization efficiency. The high P addition lines of selected did not depend on genome type or homologous group. The addition lines with high P efficiency could be used for breeding high P efficiency wheat cultivars through wild hybridization.
