| Abstract/Contents: | "Kentucky bluegrass is a popular turfgrass species with a wide range of genetic diversity. This diversity results in many distinct cultivars that can fill a large number of environmental niches. The purpose of this study was to evaluate the broad-sense heritability of various important morphological characteristics. A Kentucky bluegrass spaced-plant nursery was established in the fall of 2002 at Rutgers University, Plant Science Research Station located in Adelphia, New Jersey. One hundred and seventy-three Kentucky bluegrass cultivars and selections entered into the 2000 National Kentucky Bluegrass test sponsored by the National Turfgrass Evaluation Program (NTEP) were planted in a randomized complete block design with twelve replications. Morphological measurements were taken after anthesis during the late spring of 2004 and 2005. Measurements included: mature plant height, plant spread, panicle length, and flag leaf height, width, and length. Broad-sense heritability estimates were calculated for all morphological measurements. Mature plant height, plant spread, panicle length, and flag leaf height showed high heritability: H = 0.80. Flag leaf length was slightly less heritable, H = 0.71. Flag leaf widt was not heritable H = 0.17. The low heritability estimate observed for flag leaf width could have been due to the condition of the plants at the time the measurements were taken. Overall, these results indicated that most of the morphological characteristics in Kentucky bluegrass exhibited high heritability. Since hybrid vigor is fixed in Kentucky bluegrass through apomixis, the broad-sense heritability estimates calculated here are useful for breeding Kentucky bluegrass. Based on these results, it should be possible to select for specific morphological characteristics and fix these characters into new Kentucky bluegrass cultivars through the facultative apomictic breeding behavior of Kentucky bluegrass." |
