“…Eagleton is also tolerant of billbug ( Sphenophorus parvulus Gyllenhal) feeding (Shortell et al, 2007). Interestingly, RSP, also a Mid‐Atlantic ecotype and the mother of Cabernet (Bonos et al, 2004), did not exhibit the same high salinity tolerance in this study (Tables 1–4). RSP is known to have good summer stress tolerance under field conditions (Bonos et al, 2004), yet Wang and Huang (2004) found that it was most likely due to improved heat tolerance and not drought tolerance.…”

Salinity Tolerance of Kentucky Bluegrass Cultivars and Selections Using an Overhead Irrigated Screening Technique

An increasing amount of reclaimed water is being used in turfgrass management; however, reclaimed water is often high in total dissolved salts and can result in sait stress injury and poor turf quality. The objective of this study was to use an overhead irrigated greenhouse screening technique to identify Kentucky bluegrass {Poa pratensis L.) cultivars with increased salinity tolerance, using growth parameters and physiologicai measurements. Salt treatments were appiied using an overhead sprinkler system. Twenty-four Kentucky biuegrasses and Texas bluegrass {Poa arachnifera Torr.) x Kentucky biuegrass hybrids were established in 100% sand tanks and evaluated at a control (1 dS m^) and three salinity concentrations (3, 6, and 9 dS m ^) for a totai of 10 wk. Plants were arranged in a spiit piot design with three replications. Percent green ratings and digital images were collected weekiy and cupping weights were coliected biweekly. Root and shoot weights were taken at the end of the study. Significant differences were observed between salinity treatments and cultivars. The cuitivars Eagleton, Moonshadow, Fairfax, Cabernet, and Liberator exhibited the most salt tolerance, having the ieast decrease in growth parameters compared to the control plants (1 dS m-^), while cuitivars Baron, A03-84, and A03-TB246 were the most sait sensitive when compared to controi plants. Relative water content and photochemicai efficiency were useful to quantify physioiogical differences between tolerant and susceptibie cultivars.

“…New NTEP entries in this group included SRX 2758, A05‐360, Pick 033, SRX 466, A05‐361, and A05‐TB‐382. RSP is a known Mid‐Atlantic ecotype (Bonos et al, 2004; Supplemental Table S5), whereas ‘Wabash’ is a known Mid‐Atlantic cultivar (Funk et al, 1996; Supplemental Table S5). ‘Appalachian’ was developed as an open‐pollinated progeny of Wabash (Supplemental Table S5), whereas A05‐TB‐382 was developed from a Texas bluegrass ( Poa arachnifera Torr.)…”

An Update on the Classification of Kentucky Bluegrass Cultivars and Accessions Based on Microsatellite (SSR) Markers

et al. 2018

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.

“…Total genomic DNA was extracted from a single plant of the kentucky bluegrass cultivar Cabernet (Bonos et al, 2004) using the Sigma GenElute Plant Genomic DNA Miniprep Kit (St. Louis, MO) according to the manufacturer's instructions. DNA was sent to Genetic Identification Services Inc. (GIS, Chatsworth, CA) for construction of simple sequence repeat (SSR) libraries enriched for CA, GA, AAT, and CAG SSRs.…”

Kentucky bluegrass (Poa pratensis L.) is an important facultative apomictic temperate perennial grass species used for both forage and cultivated turf. Through apomixis, this species is able to propagate diverse and odd ploidy levels, resulting in many genetically distinct phenotypes. A wide range of diverse cultivars and accessions of kentucky bluegrass have been previously characterized based on common turf performance or morphological characteristics as well as by random amplified polymorphic DNA (RAPD) markers. Although previous characterization efforts have provided valuable information, the use of both morphological characteristics and RAPD markers for genetic diversity analysis has limitations. In the current report, we developed and characterized 88 novel microsatellite markers for kentucky bluegrass. Polymorphism for each marker was assessed in 265 kentucky bluegrass cultivars, experimental selections, collections, and hybrids. The number of alleles for individual microsatellites ranged from four to 81 with an average of 38.3 alleles per simple sequence repeat. These polymorphic microsatellite markers would be useful tools for investigating genetic diversity, creation of genetic linkage maps, assessment of levels of apomixis in cultivars and experimental varieties, and identification of aberrant progeny in apomictic kentucky bluegrass breeding programs.
