Abstract
A hybrid corn line having the designation P725, produced by crossing two maize inbreds, Qx47 and Zx23. P725 imparts a high oil level in the grain of certain male sterile hybrids when used as a pollinator. P725 is characterized by excellent seedling vigor in cold soil tests and excellent productivity in TC BLEND® Seed Corn Products of medium to late season adaptability. This invention thus relates to the seeds, plants and plant parts of P725 and its components, to plants regenerated from tissue culture of the plants of P725, to a method of producing P725, and to a method for producing high oil grain using P725 as a pollinator.
Claims18
A hybrid corn line designated P725, for which a representative sample of seeds has been deposited under ATCC Accession No. PTA-2977.
A hybrid corn seed designated P725, a representative sample of which has been deposited with the ATCC under Accession No. PTA-2977.
A method for producing a hybrid corn seed comprising the steps of
- a) planting in pollinating proximity seeds of corn inbred lines Qx47 (ATCC Accession No. PTA-2973) and Zx23 (ATCC Accession No. PTA-2979);
- b) cultivating corn plants resulting from the planting until the time of flowering;
- c) emasculating the flowers of the plants of either inbred line Qx47 or Zx23;
- d) allowing cross pollination to occur between the inbred lines;
- and
- e) harvesting seeds produced on the emasculated plants.
Corn seed designated Qx47, a representative sample of which has been deposited with the ATCC under Accession No. PTA-2973.
Corn seed designated Zx23, a representative sample of which has been deposited with the ATCC under Accession No. PTA-2979.
