Related to Colonial bentgrass: creeping bentgrass



a genus of perennial and, less commonly, annual grasses of the family Gramineae. The small, one-flowered spike-lets are gathered in loose panicles. There are approximately 200 species, distributed in the temperate and cold belts, mainly in the northern hemisphere in the mountains of tropical regions. The USSR has more than 30 species, growing mainly in the forest zone. The plants grow in meadows (often in large clusters), in glades, amid thickets, and along bodies of water.

The genus includes many forage grasses. The species A. stolonifera (formerly A. alba) and A. gigantea, which are found along wet meadows, are used for pasture and silage. Both species are grown in grass mixtures for lowland meadows. Other forage grasses include the dog bent (A. canina), which grows in the European USSR; the Siberian species A. clavata and A. trinii; and the Caucasian species A. planifolia. The Rhode Island bent (A. tenius; formerly A. capillaris) is often found in dry meadows but is rarely eaten by livestock. A number of species, including the dog bent and the Rhode Island bent, are grown for lawns. A. alpina, the cloud bent (A. nebulosa), and A. rupestris are ornamentals.

Additionally, colonial, creeping, and velvet bentgrasses all exhibited increased incidence of dollar spot and algae formation under 100% ETa, while colonial bentgrass also exhibited severe incidents of brown patch in 2003 (data not shown).
Compared among the three species, velvet bentgrass plots retained greener color, higher canopy Pn, and lower soil moisture depletion than creeping and colonial bentgrass under deficit irrigation regimes.
2% for velvet bentgrass, creeping bentgrass, and colonial bentgrass, respectively.
The three clusters corresponded to known creeping bentgrass cultivars, colonial bentgrass cultivars, and velvet bentgrass cultivars plus Agrostis canina PIs.
In this study we found that some colonial bentgrass x creeping bentgrass interspecific hybrids had excellent dollar spot resistance, whereas the creeping bentgrass pollen parents were susceptible, as were creeping bentgrass progeny from the pollen parents.
Colonial bentgrass as a species is recognized by breeders as having good dollar spot resistance (Plumley et al.
Colonial bentgrass was from the Western Regional Plant Introduction Center (PI 171470, PI 172698, PI 252045, PI 494120) and from Seed Research, Inc.
Table 3 summarizes the results of the crosses between the transgenic creeping bentgrass plants and velvet bentgrass, dryland bentgrass, redtop bentgrass, and colonial bentgrass.
Six Agrostis species, 1 diploid, 3 tetraploids, and 2 hexaploids were evaluated in this study: Velvet bentgrass (2n= 2x = 14), brown velvet bentgrass (2n = 4x = 28), creeping bentgrass (2n = 4x = 28), colonial bentgrass (2n = 4x = 28), dryland bentgrass (2n = 6x = 42), and redtop (2n = 6x = 42).
