SUPERIOR BLUEGRASSES FOR ROADSIDE TURF

This final report brings to a close research on roadsides begun in 1965, which was built on research on bluegrasses since 1952. The original objective was to develop a cultivar with definite low growth character in order to reduce the need for mowing. During the study it was determined that aggressive spread and competitive ability were necessary to provide more competition to infestations of annual and perennial weeds, even at low nutrition. The "Wabash" cultivar of Kentucky bluegrass Poa pratensis was identified as plot 1W19N as the sixth generation from a collection of plant 16B made in 1952. It is the result of annual screening of successive generations totaling over 20,000 observed individual seedlings. Wabash is medium green in color, vigorous in spread, drought tolerant, and medium in disease tolerance. It is medium in seed yield. The seed is comparatively small (average) in size-4800 seed/gram. Germination is fast (as any bluegrass) and in laboratory tests ranges from 92-96%. A plant patent, #4453, was granted for Wabash, dated 21 August 79. In three years of roadside tests Wabash has proven desirable for use on roadsides and its incorporation into seed mixtures is anticipated as commercial seed production expands. (Author)
