Narrative
The heading date of Plainsmen in Ardmore, OK is on average 5 d earlier than Jose. Seed size as indicated by 1000 seed weight, of Plainsmen (4724 mg) was greater than that of Jose (4161 mg) and Platte (3143 mg). Persistence was improved by selection, with stands of Plainsmen ranging from 90-294% greater than stands of Jose across three locations. Total autumn forage yields of Plainsmen were greater (45 and 53%) than those of Jose at Iowa Park, TX and Ardmore, OK, respectively. Crude protein and digestibility of Plainsmen and Jose were similar in both the autumn and spring, despite earlier maturity of Plainsmen. Seedling vigor, using a visual rating scale of 0 – 5, was greater for Plainsmen (4.3) than Jose (2.7). Plainsmen was released due to its improved autumn forage yield and persistence under grazing, relative to Jose.

Pedigree
Description:
A population was developed from selections from the cultivar Jose for persistence under grazing and two cycles of selection for digestibility. The parents of Plainsmen were selected using within and among family selection from this population based on autumn forage yield greater than 100% of the nursery mean.
