“…4B). In Japan, all or nearly all M. sacchariflorus are tetraploid (Hirayoshi et al, 1957) and many have introgressions from diploid M. sinensis , whereas in Russia diploidy predominates and there was no evidence of introgression with M. sinensis in our sampling range, although Hodkinson et al (2016) found putative hybrids further south in Russia. In north-east China, Jiang et al (2013) similarly found that diploid populations of M. sacchariflorus did not form an introgressed hybrid swarm with M. sinensis, though F 1 hybrids were observed there.…”

“…Although M. sinensis has been reported further inland near Lake Khanka (Herbarium at the Komarov Botanical Institute; Harkevich, 1985), we were unable to find it in that region despite deliberate searching. Hodkinson et al (2016) also did not find M. sinensis in the Lake Khanka region. The previous report of M. sinensis near Khabarovsk (Harkevich, 1985) was probably an error, given that this was very far outside of the range in which we observed M. sinensis.…”

“…The previous report of M. sinensis near Khabarovsk (Harkevich, 1985) was probably an error, given that this was very far outside of the range in which we observed M. sinensis. However, as the global climate continues to warm, we predict that the large population of M. sinensis on Russky Island, as well as coastal populations south-west of Vladivostok identified by Hodkinson et al (2016), will migrate northward into the mainland of eastern Russia and interact more with the currently well-established populations of M. sacchariflorus there. In China and Japan, where M. sacchariflorus and M. sinensis are sympatric, we have observed that M. sacchariflorus is typically restricted to riparian and wetland environments, whereas M. sinensis occupies upland sites.…”

“…This collection of Miscanthus from eastern Russia, which is being curated by the US National Plant Germplasm System, along with the collection of Hodkinson et al (2016), which is being kept at Trinity College and Teagasc, Ireland and at the Institute of Cytology and Genetics of Siberian Branch of the Russian Academy of Sciences, probably represents the maximum winter hardiness for both M. sinensis and M. sacchariflorus. Additionally, the collection includes individuals with desirable biomass traits.…”

Background and aims Miscanthus is a genus of perennial C 4 grasses native to East Asia. It includes the emerging ligno-cellulosic biomass crop M. Âgiganteus, a hybrid between M. sinensis and M. sacchariflorus. Biomass yield and cold tolerance are of particular interest in Miscanthus, given that this crop is more temperate adapted than its C 4 relatives maize, sorghum and sugarcane.Methods A plant exploration was conducted in eastern Russia, at the northern extreme of the native range for Miscanthus, with collections including 174 clonal germplasm accessions (160 M. sacchariflorus and 14 M. sinensis) from 47 sites. Accessions were genotyped by restriction site-associated DNA sequencing (RAD-seq) and plastid microsatellites.Key Results Miscanthus sinensis was found in maritime climates near Vladivostok (43Á6 N) and on southern Sakhalin Island (46Á6 N). Miscanthus sacchariflorus was found inland at latitudes as high as 49Á3 N, where M. sinensis was absent. Most M. sacchariflorus accessions were diploid, but approx. 2 % were tetraploids. Molecular markers revealed little population structure (Jost's D < 0Á007 among diploid groups) but high genetic diversity (expected heterozygosity ¼ 0Á14) within the collection of Russian M. sacchariflorus. Genome-wide association (GWA) analysis for traits measured at the collection sites revealed three M. sacchariflorus single nucleotide polymorphisms (SNPs) significantly associated with the number of stems per unit area, one with height and one with basal stem diameter; three were near or within previously described sorghum quantitative trait loci for related traits.Conclusions This new Miscanthus germplasm collection from eastern Russia will be useful for breeding Miscanthus and sugarcane cultivars with improved adaptation to cold. Moreover, a strategy is proposed to facilitate the rapid utilization of new germplasm collections: by implementing low-cost SNP genotyping to conduct GWA studies of phenotypic data obtained at collection sites, plant breeders can be provided with actionable information on which accessions have desirable traits and alleles.

“…Linear modeling using bioclimatic variables (Equation 7) predicted that the highest yielding M. sinensis for temperate regions could be collected at high elevations from ~24–32° N in China (e.g., PMS‐014; Table ) followed by S Japan, whereas the highest yielding M. sinensis for subtropical regions could be collected from the Ryukyu Islands, Taiwan and the Philippines (primarily due to large predicted culm length), and to a lesser extent coastal southeast China (Figure b and Figure S2). Notably, our model predicted the presence of M. sinensis (yields greater than zero) along coastal southeast Russia, where it has been collected recently (Hodkinson et al, ), despite our study lacking genotypes of that provenance. Model terms and coefficients are provided in Table S1.…”

Biomass yield in a genetically diverse Miscanthus sinensis germplasm panel evaluated at five locations revealed individuals with exceptional potential

To breed improved biomass cultivars of Miscanthus ×giganteus, it will be necessary to select the highest‐yielding and best‐adapted genotypes of its parental species, Miscanthus sinensis and Miscanthus sacchariflorus. We phenotyped a diverse clonally propagated panel of 569 M. sinensis and nine natural diploid M. ×giganteus at one subtropical (Zhuji, China) and five temperate locations (Sapporo, Japan; Leamington, Ontario, Canada; Fort Collins, CO; Urbana, IL; and Chuncheon, Korea) for dry biomass yield and 14 yield‐component traits, in trials grown for 3 years. Notably, dry biomass yield of four Miscanthus accessions exceeded 80 Mg/ha in Zhuji, China, approaching the highest observed for any land plant. Additionally, six M. sinensis in Sapporo, Japan and one in Leamington, Canada also yielded more than the triploid M. ×giganteus ‘1993‐1780’ control, with values exceeding 20 Mg/ha. Diploid M. ×giganteus was the best‐yielding group at the northern sites. Genotype‐by‐environment interactions were modest among the five northern trial sites but large between Zhuji, and the northern sites. M. sinensis accessions typically yielded best at trial sites with latitudes similar to collection sites, although broad adaptation was observed for accessions from southern Japan. Genotypic heritabilities for third year yields ranged from 0.71 to 0.88 within locations. Compressed circumference was the best predictor of yield. These results establish a baseline of data for initiating selection to improve biomass yield of M. sinensis and M. ×giganteus in a diverse set of relevant geographies.

Estimation of Genetic Parameters of Biomass Production and Composition Traits in Miscanthus sinensis Using a Staggered-Start Design

Traits for biomass production and composition make Miscanthus a promising bioenergy crop for different bioconversion routes. They need to be considered in miscanthus breeding programs as they are subjected to genetic and genetic x environment factors. The objective was to estimate the genetic parameters of an M. sinensis population grown during four years in two French locations. In each location, the experiment was established according to a staggered-start design in order to decompose the year effect into age and climate effects. Linear Mixed Models were used to estimate genetic variance, genotype x age, genotype x climate interaction variances and residual variances. Individual plant broad-sense heritability means ranged from 0.42 to 0.62 for biomass production traits, and were more heritable than biomass composition traits with means ranging from 0.26 to 0.47. Heritability increased through time for most of the biomass production and composition traits. Low genetic variance along with large genotype x age and genotype x climate interaction variances tended to decrease the heritability of biomass production traits for young plant ages. Most of the production traits showed large interaction variances for age and climate in both locations, while biomass composition traits highlighted large interaction variances due to climate in Orléans. The genetic and phenotypic correlations between biomass production and composition traits were moderate and positive, while hemicelluloses were negatively correlated with all traits.Efficient genetic progress is achievable for miscanthus breeding when plants get older. The joint improvement of biomass production and composition traits would help provide a better response of miscanthus to selection.
