| Abstract/Contents: | "In the past evaluation of cultivars for turfgrass use has,in the main, been carried out subjectively using visual scores. Many of the characteristics which have been associated with turfgrass merit can also be investigated using objective techniques. These include: shoot density, fineness of leaf, colour, disease susceptibility, shoot size, thatch accumulation and leaf number per shoot. The correlations between objectively measured turf characteristics and the relationships between such characteristics and subjectively perceived merit are discussed. Shoot density was negatively correlated with fineness of leaf and and shoot size, but positively correlated with depth of thatch. There was no correlation between shoot density leaf number per shoot. A strong association between turfgrass merit and shoot density was found. The relationship between merit and the measured turf characteristics was examined further using stepwise regression. Approximately 70% of the variation in turfgrass merit could be accounted for by differences in shoot density. Much smaller, but significant, amounts of the variation could be accounted for by leaf width, disease susceptibility and colour. The current differences between sub-species of red fescue Festuca rubra ssp. commutata (Chewings fescue), ssp. litoralis (slender creeping red fescue) and ssp. rubra (strong creeping red fescue) are also discussed. There was little difference between Chewings and slender creeping red fescues, except in disease resistance. Chewings fescues were more resistant to red thread and dollar spot. Strong creeping red fescues maintains smaller shoot densities and had coarser leaves. They were also more susceptible to turf diseases than Chewings fescues. |
