“…1) were not as apparent as it was reported in Honig et al (2012). In short, little bootstrap support was detected among broader clades between the classification types in the current analysis vs. Honig et al (2012) (with the exception of the expected close relationship between the Sydsport and Shamrock classification types [Bailey et al, 1995] found in both studies). Reasons for this lack of higher level SSR marker‐based clade groupings may be due to high within‐population variance detected via AMOVA, differences of key entries included in this study vs. Honig et al (2012), hybridization between classification types within certain individual entries (as seen in STRUCTURE admixture patterns, Fig.…”

Kentucky bluegrass (Poa pratensis L.) is an important perennial forage and amenity turfgrass species used throughout temperate regions in North America and Europe. Kentucky bluegrass cultivars and accessions exhibit a wide range of ploidy levels, morphological traits, turfgrass quality characteristics, and tolerances to both biotic and abiotic stresses. As such, cultivar classification systems have been developed to categorize Kentucky bluegrass cultivars and accessions on the basis of pedigree, turf performance, morphological traits, and genetic relatedness (DNA markers). The objectives of the current study were to assess the genetic diversity among and within Kentucky bluegrass entries using simple sequence repeat (SSR) markers, and to categorize new germplasm in the Kentucky bluegrass classification system. In this study, 21 SSR markers were used to genotype eight individuals from each of 144 bluegrass cultivars and accessions (1152 total samples). The SSR markers successfully categorized all entries into distinct classification groups and provided justification for a partial revision to the previous DNA marker‐based classification system. The majority of cultivars and accessions were uniquely identified with the current set of SSR markers, and SSR marker‐based genetic relationships of individuals within classification types showed agreement with breeding history records. Over 60 new Kentucky bluegrass National Turfgrass Evaluation Program entries were placed into updated classification groups, and the SSR markers used in this study can be used in the future to genotype and assign new cultivars and accessions into Kentucky bluegrass classification types and assess the genetic relatedness among entries.

Over the past several decades, breeding cool-season turfgrasses for improved disease resistance has been the focus of many turfgrass breeding programs. This review article discusses the dramatic improvements made in breeding Kentucky bluegrass (Poa pratensis) for resistance to leaf spot (caused by Drechslera poae), stem rust (caused by Puccinia graminis), and stripe smut (caused by Ustilago striiformis); perennial ryegrass (Lolium perenne) for resistance to gray leaf spot (caused by Pyricularia grisea), stem rust and crown rust (caused by Puccinia coronata); tall fescue (Festuca arundinacea) for resistance to brown patch (Rhizoctonia solani) and stem rust; creeping bentgrass (Agrostis stolonifera) for resistance to dollar spot (caused by Sclerotinia homoeocarpa); and fine fescues (Festuca spp.) for improved disease resistance. Historically, the dramatic improvements in disease resistance of the cool-season grasses have been attributed to traditional/conventional breeding techniques; however, it is likely that functional genomics and molecular techniques will play a more significant role in the development of cultivated turfgrasses as the specific genes and mechanisms for disease resistance are identified in the future.
