2011 Annual Report

1a. Objectives (from AD-416)
Evaluate and make selections across approximately 100 festuca interspecific hybrids at Kansas State University, Southeast Agriculture Research Center, Parsons, KS.

1b. Approach (from AD-416)
Interspecific hybrids developed at ARS in EL Reno, OK, will be transplanted in a spaced planting nursery near Mound Valley, KS, that is operated by the Southeast Kansas Agricultural Research Center, Parsons, KS. Hybrids will be evaluated for tolerance to local diseases, local environmental stress components, vigor, appearance, and crude protein content. Following 1-2 years of selection, exceptional surviving individuals will be intercrossed and seed bulked for 3-4 years of performance testing.

3. Progress Report
Seventy F1 ryegrass x fescue hybrids were harvested for their infloresences. Germinations were undertaken of potential seed set on each respective individual. Sixty-two individuals generated some level of seed set. Of these, 59 hybrids were confirmed to generate dihaploid tall fesue and ryegrass recoveries. One dihaploid obtained from each parental F1 hybrid was transplanted to the KS nursery for a study on forage quality estimates between the F1 and the dihaploid recovery. The ADODR monitored the activities of this agreement through email, conference calls and on-site visits.
