1. WB7566 (DA909-325) is a hard white spring wheat developed by the Monsanto LLC.
2. In early generations of WB7566, single spikes were selected based on agronomics and disease resistance. Later generations were selected based on yield, quality, and disease resistance.
3. WB7566 is adapted to the hard spring wheat growing regions of the Southwestern region of the United States.
4. Preliminary data indicates that WB7566 may be resistant Stripe Rust.

Variants and frequency:
A variant that is similar to WB7566 but has red seed occurs at a frequency of up to .2% (20 out 10,000 seeds). A variant that is similar to WB7566 but is 15cm to 20cm taller occurs at a frequency of up to .2% (20/10,000). A bronze head variant may occur at a frequency of .1% (10/10,000). An awnless variant may occur at a frequency of .1% (10/10,000).
6. Recognized classes of WB7566 are breeder, foundation, registered, and certified. Monsanto Company will maintain the variety by the head-row purification method to produce breeder seed as needed and all foundation seed. Royalty fees and/ or licensing agreements are anticipated.
7. Commercial seed of WB7566 will likely be ready for commercial sale by the spring of 2016.
8. Application for a Utility Patent and PVP is anticipated for WB7566, but the option for Title V will not be taken.
