Abstract/Contents:"At first thought, it would seem easy to find drought tolerant grasses. The immediate solution seems to be to look around the area, and simply select and improve grasses that grow on dry sites. And, for real drought tolerance, grasses growing on excessively dry sites in arid and semi-arid regions would seem to be good candidates for drought tolerance. One problem with this is that a seemingly dry area may have subsoil moisture (not detectable on the surface), runoff may provide extra water, shade may reduce grass water needs, or the grass may have wide spreading roots to take advantage of water available adjacent to the grass plant." "For quality turf, cultivars (varieties) of Kentucky bluegrass, perennial ryegrass, fine fescue and turf-type tall fescues are widely grown in cool humid and semi-arid regions in the U.S. Significant differences occur in drought tolerance among cultivars of these grasses. Tests of 55 varieties of Kentucky bluegrass, 34 perennial ryegrasses, and 42 fine fescues at Colorado State University, under moderate to severe drought over 2 seasons, indicated: 1) 'A-20-6', 'H-7', 'America' and 'Majestic' had improved drought tolerance. Of these, 'H-7' and 'Majestic' had superior drought tolerance. 2) 'Aristocrat', 'Bellatrix', 'Citation', and 'Yorktown' perennial ryegrass had improved drought tolerance. 3) None of the fine fescues studied provided acceptable turf under the existing drought conditions. However, the hard fescues were generally more drought tolerant than other fine fescues." "Smooth bromegrass, a common sod forming forage grass, has good drought tolerance and other attributes that make it a serious candidate for turf use in cool areas." "As a rule, for turfgrass drought improvement, selection on site seems to offer promise. In order to fully utilize traditional breeding techniques, tissue culture, gene splicing, etc., material known to be exceptionally drought tolerant needs to be available. Only limited information on turfgrass species and varietal performance under drought conditions exists, and at this time this is probably insufficient to allow modern technology to make needed significant turfgrass advancements."
