“…The transition of chromosome numbers from 10 to 19 may be hypothesized to be due to a polyploidization after the divergence of Sorghinae and Saccharinae about 8 million years ago (Kim et al 2009), however, the alternative possibility of chromosomal fission(s) has not yet been falsified. Cai et al (2005) successfully applied sugarcane SSRs to the Saccharum complex including Miscanthus. In a similar manner, we designed SSRs from sugarcane expressed sequence tags (ESTs) and applied them to a Miscanthus mapping population, in order to generate EST-SSR-based genetic maps of Miscanthus.…”

We present SSR-based genetic maps from a cross between Miscanthus sacchariflorus Robustus and M. sinensis, the progenitors of the promising cellulosic biofuel feedstock Miscanthus × giganteus. cDNA-derived SSR markers were mapped by the two-way pseudo-testcross model due to the high heterozygosity of each parental species. A total of 261 loci were mapped in M. sacchariflorus, spanning 40 linkage groups and 1,998.8 cM, covering an estimated 72.7% of the genome. For M. sinensis, a total of 303 loci were mapped, forming 23 linkage groups and 2,238.3 cM, covering 84.9% of the genome. The use of cDNA-derived SSR loci permitted alignment of the Miscanthus linkage groups to the sorghum chromosomes, revealing a whole genome duplication affecting the Miscanthus lineage after the divergence of subtribes Sorghinae and Saccharinae, as well as traces of the pan-cereal whole genome duplication. While the present maps provide for many early research needs in this emerging crop, additional markers are also needed to improve map density and to further characterize the structural changes of the Miscanthus genome since its divergence from sorghum and Saccharum.

“…A recent diversity study carried out to determine the genetic relationship of E. rockii to the Saccharum complex determined that E. rockii is most similar to E. fulvus, Miscanthus sinensis and Miscanthus floridulus (Cai et al 2005b), indicating it is more closely related to Miscanthus and E. fulvus than to other Erianthus species. Previous to this E. rockii had only been classified in China as one of eight species in Erianthus (Chen 1997).…”

Erianthus rockii, a wild relative of sugarcane, is drought and cold tolerant, and both are potentially important agronomic traits to the sugarcane industry worldwide. As such it is of interest as a source of parental germplasm to sugarcane breeders and is currently being used in sugarcane introgression programs in both China and Australia. To date morphological characters have been used to verify the putative hybrids produced. Two crosses were generated between two different Saccharum species and two E. rockii accessions. Over 400 AFLP markers were used to identify the intergeneric hybrid progeny as well as determine hybrid diversity. Both crosses generated hybrids but efficiency levels were very different and are probably related to the different Saccharum parent used in each cross. Cross 1 was between a Saccharum officinarum and E. rockii and generated 100% hybrid progeny. Cross 2, however, was between a sugarcane hybrid (S. officinarum · Saccharum spontaneum) and E. rockii and only 10% of the progeny were intergeneric hybrids. Inheritance of markers in the progeny was analysed and for both crosses there were equal numbers of markers from both parents indicating n + n transmission of chromosomes. This is the first verification of E. rockii hybrids with molecular markers. It may now be possible to exploit genes of value from E. rockii in sugarcane breeding programs.

“…Miscanthus is closely related to other genera of the "Saccharum complex" (the Saccharum genera belonging to this complex) and Saccharum-Miscanthus hybrids, that is, miscanes, are used to create varieties of miscane [12]. Alix et al [13] (Table 4.1) concluded that Miscanthus was more similar to Saccharum than Erianthus while Cai et al [14] (Table 4.1) placed Miscanthus between Erianthus and Saccharum. However, a phylogenetic analysis of more than 57 species belonging to the tribe Andropogoneae showed that Saccharum was in fact more closely related to Miscanthus than to other species in the Saccharum complex [11].…”
