“…Genetic instability of Tifgreen gave rise to off-type grasses of variable phenotypes that appeared soon after establishment (Caetano-Anollés 1998; Caetano-Anollés et al 1997). In many cases, these off-types exhibited superior characteristics and were later propagated and released as commercial cultivars.…”

“…In addition, Tifdwarf had softer leaves, fewer seed heads, darker green color, and slightly greater winter hardiness than Tifgreen (Burton 1965, 1966a; Burton and Elsner 1965). The genetic instability of Tifdwarf was similar to Tifgreen (Burton 1965, 1966a; Caetano-Anollés et al 1997; Caetano-Anollés 1998); therefore, widespread use of Tifdwarf, like Tifgreen, facilitated the selection of off-types that were later released as commercial cultivars.…”

“…They were identified as off-types in putting surfaces, because of differences in morphology and performance (Caetano-Anollés 1998; Caetano-Anollés et al 1997). The presence of off-type grasses spurred research exploring the genetic stability of Tifgreen and Tifgreen-derived cultivars.…”

“…A later interspecific hybrid, ‘Tifgreen’, improved putting quality, because it could be maintained at lower mowing heights while sustaining optimum leaf density and canopy coverage (Burton 1964; Hein 1961). Shortly, after its commercial release, off-types (grasses with differences in morphology and performance when compared to the surrounding desirable cultivar (Caetano-Anollés 1998; Caetano-Anollés et al 1997)) began appearing in established putting greens (Burton 1966a; Burton and Elsner 1965). …”

Main conclusionSome interspecific hybrid bermudagrass cultivars used on golf course putting greens are genetically unstable, which has caused phenotypically different off-type grasses to occur in production nurseries and putting surfaces. Management practices to reduce the occurrence of off-type grasses in putting green surfaces and the effect they can have on putting quality and performance need to be researched until genetically stable cultivars are developed.Golf course putting green surfaces in subtropical and tropical climates are typically planted with an interspecific hybrid bermudagrass (Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt-Davy), because of the superior putting quality and performance of these cultivars. ‘Tifgreen’ was one of the first interspecific hybrids developed for putting green use in lieu of common bermudagrass. However, off-type grasses began appearing in established Tifgreen stands soon after commercial release. Off-type grasses are those with different morphology and performance when compared to the surrounding, desirable cultivar. Off-types have the potential to decrease surface uniformity, which negatively affects putting surface quality. However, several unique off-types from Tifgreen have been selected as commercial cultivars, the first being ‘Tifdwarf’; then ‘Floradwarf’, ‘MS-Supreme’, ‘Pee Dee-102’, and ‘TL-2’, identified later. The cultivars ‘Champion Dwarf’, ‘P-18’, ‘RJT’, and ‘Emerald Dwarf’ were subsequently selected as off-types in Tifdwarf. The naturally occurring off-types and cultivars that have been identified within the Tifgreen family have widely differing phenotypes; however, they are reported to be genetically similar, supporting the hypothesis that their occurrence is a result of somatic mutations. Genetic instability in currently available commercial cultivars is likely to lead to the continued presence of off-types in production nurseries and putting greens. Additional research is needed to understand the nature of genetic instability in Tifgreen-derived cultivars and how to manage its consequences to develop new cultivars, but also strategies for eradication of off-types in pedigree nursery production and end-site putting greens.

“…Different DNA markers have been used in studies of genetic diversity, relatedness, phylogeny, and in identifying off-types of Cynodon cultivars . DNA amplification fingerprinting (DAF) [9] has been used to study relatedness of some genotypes (clonal plants) of C. transvaalensis , C. dactylon , and hybrid derivatives of the two species [10,11], detect off-types originating from sod contamination instead of somatic mutation, and to identify the cultivars Tifway, Tifgreen, and Tifdwarf [12], Furthermore, DAF has been used to examine the relatedness of 18 Cynodon cultivars found in Australia [13], to assess genetic relatedness among 62 Cynodon accessions representing eight species [14], to assess the genetic relatedness of 17 seed-propagated turf-bermudagrass cultivars [15], and to determine the degree of genetic relatedness of Chinese cultivars with the existing vegetative cultivars commonly grown in the United States [16]. Randomly amplified polymorphic DNA (RAPD) [17] was used to evaluate diversity of 75 C. dactylon accessions collected from different regions of Iran [18].…”

Although Cynodon dactylon (C. dactylon) is widely distributed in China, information on its genetic diversity within the germplasm pool is limited. The objective of this study was to reveal the genetic variation and relationships of 430 C. dactylon accessions collected from 22 Chinese provinces using sequence-related amplified polymorphism (SRAP) markers. Fifteen primer pairs were used to amplify specific C. dactylon genomic sequences. A total of 481 SRAP fragments were generated, with fragment sizes ranging from 260–1800 base pairs (bp). Genetic similarity coefficients (GSC) among the 430 accessions averaged 0.72 and ranged from 0.53–0.96. Cluster analysis conducted by two methods, namely the unweighted pair-group method with arithmetic averages (UPGMA) and principle coordinate analysis (PCoA), separated the accessions into eight distinct groups. Our findings verify that Chinese C. dactylon germplasms have rich genetic diversity, which is an excellent basis for C. dactylon breeding for new cultivars.

Cynodon Rich. is one of the major turfgrass and forage genera in warmer climates of the United States and other world regions. New cultivars of Cynodon spp. are often developed by hybridization of a limited number of accessions of two species—C. transvaalensis Burtt Davy and C. dactylon (L.) Pers.—or by selection from existing cultivars. This may lead to an erosion of diversity. Several other species of this genus also exhibit desirable traits, and they could be used in the development of new cultivars to increase the range of genetic variation. In this study, the genetic diversity of seven Cynodon species was assessed using Diversity Array Technology sequencing (DArTseq). This technology is capable of identifying single nucleotide polymorphism (SNP) markers with no prior DNA sequence information. The 85 analyzed accessions showed considerable genetic variation and formed several distinct groups based on the degree of relatedness. However, none of these groups were comprised of only accessions of the same species, suggesting that DNA marker groupings are not well in agreement with botanical classification for this genus. The identification of species‐specific SNP markers provides an additional tool for species reclassification and may clear up pedigrees of some established cultivars.
