Current trends toward energy conservation in home landscaping present problems in warm-season turfgrass selection since all species grow best in full sunlight. Previous research has identified several St. Augustinegrass [Stenotaphrum secundatum (Waltz.) Kuntze] selections with excellent shade and cold tolerance. To determine if germplasm samples are truly different than established cultivars, morphological traits were evaluated. The objective of this study was to determine if experimental St. Augustinegrass germplasm samples possessed different morphological differences compared to industry standards, ‘Raleigh’ and ‘Palmetto’. Turf height measurements, visual seedhead density counts and morphological measurements were taken to quantify leaf width, leaf length, and internode distance. Measurements were taken at the third internode of each stolon. Internode distance was measured between the third and fourth internode. Significant differences between leaf width, leaf length, and internode distance occurred as did differences between turf height and seedhead density when compared to the industry standards, ‘Raleigh’ and ‘Palmetto’ St. Augustinegrasses. Findings suggest these germplasm samples have sufficient different morphological characteristics to indicate they are probably different cultivars. Differences in morphological characteristics is one tool used to determine differences between cultivars. Additional verification is justifiable if technology advances allow genetic sequencing to be definitive enough to determine if these grasses are truly different. As homeowners trend towards greater energy efficiency, demands for better performing, more shade tolerant turfgrasses also increase. Current trends toward energy conservation in home landscaping present problems in warm-season (C4) turfgrass selection since all species grow best in full sunlight. As the use of shade for cooling homes and buildings has increased, the need for a shade and cold tolerant turfgrass by homeowners and landscapers has arrived [1-3]. To determine if germplasm samples are truly different cultivars than established ones, morphological traits are typically evaluated to justify further research such as genetic sequencing. In addition, turf height and seedhead production differences would be valuable information for those turf managers interested in cultivars not requiring as frequent mowing as others. Genotypic sequencing, however, isn’t always able to delineate between cultivars. In hybrid bermudagrasses (Cynodon dactylon (L.) Pers. x C. transvaalensis Burtt-Davy), genotyping-by-sequencing was unable to consistently distinguish triploid standard cultivars from one another [4]. Researchers also were not able to distinguish these selections from their parents due to similar origin and clonal propagation but could distinguish triploids from diploid and tetraploid samples. To the author’s knowledge, molecular genotyping of St. Augustinegrasses has yet been published. Busey [5] classified 94 gentotypes based on 26 characters into five groups and developed a key based on their geography, chromosome number, and adaptation characteristics. The objective of this study was to determine if experimental St. Augustinegrass germplasm samples possessed different morphological differences compared to industry standards ‘Raleigh’ and ‘Palmetto’
