| Abstract/Contents: | "The USGA/TAES Zoysiagrass Breeding and Development Program is a diverse, multifacited approach to expand and improve existing cultivars of the Zoysia species. Constant observation of the plant collection reveals both the strengths and weaknesses of this turfgrass. A taxonomic study of Zoysia spp. germplasm was initiated to gain a better understanding of their breeding behavior. The genetic variability within the Oriental germplasm, collected four years ago in Southeast Asia with support from the USGA, continues to be evaluated in the field, greenhouse, and laboratory. Field notes were taken during the last year for fall color, growth rate, leaf type, spring greenup, flowering habit, percent cover, dormancy, and canopy temperature. Significant variation exists with the germplasm for all of these characters, and the probability of creating genotypes which possess favorable gene combinations are excellent. A test of the compatibility of the germplasm accessions was initiated during Spring 1985 in both the greenhouse and the field. A commercially available Korean zoysiagrass seed stock was screened for tolerance to high soil temperatures and low soil moisture. Plants selected for superior performance during prolonged temperature and moisture stress, and those selected for their ability to recover from stress conditions differed significantly from an unselected base population. A field study using the selected and unselected populations was initiated to further examine the tolerance of this plant material to heat and moisture stress in the natural environment. Attempts to produce single cross hybrids between individual zoysiagrass accessions were unsuccessful thus far. Several crossing techniques will be evaluated during the next year. A growth chamber constructed during the last year was useful in initiating plants to flower. Open-pollinated seedlings from 1983 to 1984 were planted to the field in Summer 1985. Eighty six families (i.e., the maternal parent and its open-pollinated offspring) were established in a replicated field trial to study the level of genetic variation for major agronomic characters, and provide accurate estimates of heritability. Such information is essential in determining the most effective breeding method to employ in cultivar development. Forty cultivars were evaluated for sod strength and rate of regrowth after sod harvest. Three accessions have outstanding rhizome regrowth potential. These accessions and other cultivars will be planted into a new variety trial in Spring, 1986. A seed production trial was also initiated in August 1985 to help determine the potential for a seeded zoysiagrass variety." |
