文摘

Phosphorus (P) concentrations and use efficiency were assessed in working fields using 127 recombinant inbred lines. Low straw P concentration was associated with high PUEg. Growth duration did not affect PUEg and negatively affected grain P concentration. There was no correlation between grain concentration and straw P concentration. Grain P concentration was relatively stable across recombinant inbred lines RILs.
