Interpretive Summary: To meet the needs of growers in the southeastern US, FL16045-25, a soft red facultative wheat cultivar, was released by the University of Florida. FL16045-25 is well adapted, from Texas to Virginia, and provides producers with an early-season, facultative, medium height, awned, semi-dwarf cultivar that has high yield potential, good straw strength, and good grain volume weight and end-use quality. It expresses moderate to high levels of resistance to most diseases prevalent in the southern U.S. The yield average of FL16045-25 from 41 environments during 2020-2022 is competitive with check varieties that are widely used in the southern part of the U.S and grain volume weights (test weight) were higher. This variety was made available for licensing.

Technical Abstract: FL16045-25 (Reg. no. CV-1207, PI 704484), a soft red facultative doubled-haploid wheat (Triticum aestivum L.) cultivar, developed and tested as FL16045DH-25 by the University of Florida, was released in October 2022. FL16045-25 was derived from the cross MD07W478-14-5/GA06112-13EE16. It is well adapted, from Texas to Virginia, and provides producers with an early-season, facultative (Vrn-A1_short), medium height, awned, semi-dwarf (Rht2) cultivar that has high yield potential, good straw strength, and good grain volume weight and end-use quality. It expresses moderate to high levels of resistance to most diseases prevalent in the southern U.S. Molecular marker analysis confirms the presence of Sbm1, Yr17/Lr37/Sr38, Lr18, Sr36/Pm6, Pm54, and Pm1a linked disease resistant genes. The yield average of FL16045-25 from 41 environments during 2020-2022 ranged from 4211 to 5782 kg ha-1 which is competitive with check varieties that are widely used in the southern part of the U.S. The grain volume weight of FL16045-25 ranged from 749 to 785 Kg m-3 (32 environments) which was higher than most of the checks. FL16045-25 has soft grain texture with softness equivalence varying from 51.3 to 59.3% and sodium carbonate solvent retention capacity (SRC) ranging from 66.8 to 68.5%. Flour yields on a Quadrumat Senior milling system varied from 68.7 to 69.5%. Flour protein content varied from 8.9 to 9.1%. Cookie spread diameter varied from 19.4 to 19.5 cm. The presence of TaSus2-2B, Sucrose Synthase2 gene on 2B or 2G:2B, was confirmed by marker analysis.
