Evolution of Improved Lawngrasses in America: A Review of Major Events Leading to the Kentucky Bluegrass Cultivar Revolution1
- R. W. Schery
Cool-season lawngrasses from Europe spread widely in America to yield many ecotypes [as with Kentucky bluegrass (Poa pratensis L.)] that were quite adaptable. Discovery and market development of ‘Merion’ Kentucky bluegrass showed that isolates from this huge gene pool could yield superior cultivars finding public acceptance at a premium. Hybridization work in several sections of the country proved the advantage of crossing select parental lines. Development of new cultivars first received serious commercial attention in Europe and then, upon passage of “breeder's rights” legislation, in the United States. Now sophisticated breeding techniques join selection from adventive stands to produce a plethora of fine cultivars. Fortunately, the breeding of ever-better lawngrasses is not seriously threatened by extinction of landraces, as is occurring with many major agricultural species.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
