Description
This study was undertaken to determine the forage potential of Texas bluegrass (Poa arachnifera Torr). Texas bluegrass is a perennial coolseason grass native to Kansas, Oklahoma, western Arkansas, and the central region of Texas, USA (Gould, 1975). Thirteen different accessions were established in 1988 at the Texas A&M University Centers at Dallas and Stephenville and tested for 2 years. Mean yields at Stephenville and Dallas were 3610 and 6022 kg ha-1. Two synthetic varieties (Syn-1 and Syn-2) were tested from 1990 to 1995 at four locations in Texas. Yields of Syn-1 was greater than Syn-2 whereas Syn- 2 provided significantly higher mortality than Syn-1 of larvae of the fall armyworm (Spodoptera frugiperda (J.E. Smith)) in nochoice laboratory feeding tests.
