![]() Camus-that grow in a wide range of climatic conditions. Ripidium, Narenga Bor, and Sclerostachya A. The complex includes five interbreeding genera- Saccharum L. The genus Erianthus, which belongs to the “ Saccharum complex”, includes C 4 warm-season grasses. ĭiverse germplasm collections are essential for stable preservation and maintenance of ecotypes that might adapt to climate changes these collections could provide indispensable materials for the development of novel cultivars with such adaptations. Thus, the establishment of sustainable agricultural production systems resilient to global climate change is one of the critical challenges that humans will face in the near future. Global climate change may affect stable agricultural production by causing droughts, floods, high-temperature injury, and emergence of novel pests. Global warming will unavoidably harm food production, ecosystems, and water resources, and advance preparation is necessary to adapt to climate change. This knowledge would allow efficient maintenance and conservation of the genetic resources of this grass and would help to use Erianthus species as breeding materials for development of novel bioenergy crops and sugarcane improvement.Īccording to the Fifth Assessment Report (AR5: 2013–2014) of the Intergovernmental Panel on Climate Change (IPCC), since the middle of the twentieth century, the natural environment has been exposed to severe global warming caused by human activities, and urgent mitigation efforts are needed, including energy-saving measures and the introduction of renewable energy sources. ![]() The molecular approach used in this study characterized the genetic diversity and relatedness of Erianthus germplasms collected across Thailand. The analysis of genetic structure and phylogenetic relationships, however, found some accessions whose classification contradicted the results of previous phenotypic classification. The results of principal coordinate analysis and phylogenetic analysis of the 121 accessions on the basis of the SSR markers showed the same trend as Bayesian clustering, whereas sequence variations of three non-coding regions of chloroplast DNA revealed eight haplotypes among the accessions. A Bayesian clustering approach with these alleles classified the accessions into four main groups, generally corresponding to the previous classification based on phenotypic analysis. arundinaceus were used to assess the genetic diversity of 121 Erianthus germplasms collected in Thailand of these primer pairs, 28 detected a total of 316 alleles. ResultsĪ set of 41 primer pairs for nuclear simple sequence repeats (SSRs) developed from E. However, the genetic differences and relatedness of the germplasms are not fully understood. arundinaceus have been collected over the past 20 years and their phenotypic traits have been evaluated. ![]() arundinaceus has accelerated the collection and conservation of its genetic resources, mainly in Asian countries, and also evaluation of morphological, agricultural, and cytogenetic features in germplasm collections. Recently, this species has attracted attention as a novel bioenergy crop and as a breeding material for sugarcane improvement. Erianthus arundinaceus (Retz.) Jeswiet is highly adaptable to the environment, has a high percentage of dry matter, and is highly productive. Erianthus species are widely distributed throughout Southeast Asia, East Asia and South Asia.
