| Abstract/Contents: | "As new Cynodon varieties are developed, varietal characterization and identification is becoming increasingly important. Seeded cultivars being developed consist of F1 hybrids, and multiple and two clone synthetics. Intra-specific, seeded propagated hybrids have shown turf quality characteristics that are similar in genetic uniformity as well as appearance as many inter-specific, sterile, single clone hybrids. Mean separartions and phenotypic variability were estimated for several classes of Cynodon cultivars from data on several morphological characteristics collected over two years at Las Cruces, NM. The phenotypic data were then compared to molecular characterization using RAPD marker analysis. Molecular data were collected on the same genotypes grown at Las Cruces and were used to estimate genetic distance that exists among populations and genotypes. Results indicated that newly developed F1 fertile hybrids have more genetic uniformity than multiclone synthetic cultivars for vegatative characteristics but segregate for components of seed yield. Genetic distances among the populations and individual genotypes were highly significant (P<0.01), with groups clustering in the same order as the phenotypic characterizations. Preliminary evidence using a combination both phenotypic evaluation on morphological traits and RAPD marker technology may improve, not only quality control measures of proprietary material, but also selection efficiency in breeding and development programs." |
