“…Moreover, in the USA, the most prevalent clone available in the public domain is designed “Illinois” and propagated from a plant growing at the Chicago Botanic Gardens [25], which was originally received from Europe and was of the same genetic identity as the M. × giganteus genotype widely propagated in Great Britain [26]. This indicated that a narrow gene pool of M. × giganteus existed.…”

“…This indicated that a narrow gene pool of M. × giganteus existed. It should be emphasized that cultivation based on genetically uniform unimproved clones is inadequate on the grounds of: disease risk, overwintering problems during the first vegetative season, relatively expensive establishment or varying plant quality requirements for different uses [8, 17, 26, 27]. On account of the above mentioned facts, a crucial factor in Miscanthus crop improvement programs is the collection and utilization of diverse germplasms [26].…”

Miscanthus: Genetic Diversity and Genotype Identification Using ISSR and RAPD Markers

Due to the limited number of molecular studies focused on European gene pool investigation, it is necessary to perform plant material recognition. Eighteen accessions of three Miscanthus species, namely, M. × giganteus, M. sinensis, M. sacchariflorus were evaluated with the use of molecular marker systems such as: inter simple sequence repeats (ISSRs), random amplified polymorphic DNA (RAPD), and by estimation of ploidy level based on flow cytometry. As a result, only one ISSR primer (ISSR1) and three RAPD primers (RAPD1, RAPD2, RAPD4) were required to identify all genotypes. Moreover, the use of the above mentioned molecular markers enable the proper species recognition of the interspecific hybrid M. × giganteus “Floridulus,” which has been previously mislabeled as M. floridulus. The highest genetic similarity coefficient (0.94) was observed between M. × giganteus clones, which indicates that the genetic diversity within this species was very low. Whereas M. sinensis genotypes represented a relatively wide diversity with similarity coefficient of 0.58. Cluster analysis using UPGMA grouped the 18 accessions in three clusters according to species affiliation including relabeled M. × giganteus “Floridulus,” which proved to be closely related to M. × giganteus. Similar groupings were evident in the PCoA analysis.

“…However, this highly productive crop is sterile and reproduces vegetatively from micropropagated plantlets or rhizomes in spring (Greef & Deuter, 1993). M. × giganteus seems to be sensitive to drought and low temperatures, which restricts its industrial production in many regions (Heaton et al, 2010;Anderson et al, 2011). Owing to the narrow genetic pool, establishment costs and sensitivity to cold temperature of M. × giganteus, the development of other species must be considered.…”

“…Investigations of the biomass yield and agronomic performance of Miscanthus and Saccharum have mostly been carried out in Europe and the USA but similar efforts are lacking in China. Heaton et al (2010) reported that many primary colonizers had high productivity, which turned out to be a feature that was selected during evolution. Most species of Miscanthus and Saccharum are endemic to eastern or southeastern Asian countries such as China, Japan and the Philippines (Chen & Renvoize, 2006;Clifton-Brown et al, 2008).…”

Miscanthus and Saccharum are considered excellent candidates for bioenergy feedstock production. A field experiment was conducted in Zhejiang province of China to characterize the phenotypic differences in three species, two of Miscanthus (M. sinensis and M. floridulus) and one of Saccharum (S. arundinaceum), each with two accessions collected from China. Agronomical traits, including plant height, culm number, tuft diameter and culm diameter, were monitored monthly for the first 3 years of growth. For each year of trail, flowering time was observed and biomass yield was harvested. M. floridulus produced a superior biomass yield with increasing plant age associated with higher yields (4.18, 24.16 and 29.01 t dry matter/ha in November of years one to three, respectively). Higher culm diameter, plant height and tuft diameter values were observed for M. floridulus when compared to the other species. Biomass yield was positively correlated to tuft diameter, culm diameter, culm number and negatively to flowering time, but it showed no correlation with plant height. Tuft diameter and culm diameter could be suitable indicators in the selection of accessions for crop yield at the yield-building phase. Studies of the primary colonizers of Miscanthus and Saccharum in their original location may be of interest from the perspective of bioenergy germplasm resource collection.Additional key words: agronomic traits; perennial grasses; correlation analysis.
