Phosphorus use efficiency in maize breeding

Due to large area of phosphorus (P) deficient soils worldwide, breeding for P use efficiency becomes of commercial interest in maize. In this study, results from experiments grown in Croatia in 2003 and 2004 were presented in order to examine P efficiency in two well-known Os hybrids as well as in their respective parents and four crossing generations. The two- year trial was planted at two locations (Zelčin and Gundinci) differing markedly in P concentrations in soil. The results showed that patterns in differences of P efficiency over the years varied across generations: all four parents (respective R1 and R2) in both hybrids had the smallest differences compared to other generations. Two parents varied markedly for mean P efficiency in OSSK596. The parent R1 had P efficiency greater than 100% in both years, showing that this BSSS inbred line had consistently higher grain yield on P-deficient soil. Generally, no heterosis was expressed in this hybrid. On contrary, two inbred parents in OSSK 602 had similar P-efficiencies. There was heterosis for P efficiency in this hybrid in 2004, but further work is required to clarify this occurrence.
