An Approach to Turfgrass Cultivar Evaluation1

Abstract

Abstract

The release of many new turfgrass cultivars and experimental selections for testing by experiment stations and quantity of resources needed to evaluate each candidate has placed a tremendous burden on research personnel. A multiphase system of evaluation is proposed for more efficiently determining the limits of adaptation and obtainable quality levels for cultivars within a region. The system includes: Phase I, evaluation to establish performance characteristics of cultivars sustained under a “moderate intensity” of culture; Phase II, evaluation to determine the mowing, fertilization, and irrigation requirements of the cultivars for best quality, as well as their range of adaptation within a prescribed cultural intensity spectrum; Phase III, evaluation to determine the limits of environmental adaptation for each cultivar and any unique features that affect its potential use.

Results of cultivar evaluations conducted in Urbana, III. are reported and some of the problems encountered in reporting data are discussed. Conclusions are based on evaluations conducted with over 40 cultivars of Kentucky bluegrass (Poa pratensis L.) and perennial ryegrass (Lolium perenne L.)
