Rice genetic resources, comprising landrace varieties, modern and obsolete varieties, genetic stocks, breeding lines, and the wild rices, are the basis of world food security. The International Rice Genebank at the International Rice Research Institute in the Philippines conserves the largest and most diverse collection of rice germplasm. The facilities of the genebank ensure the long-term preservation of this important diversity. In field research, factors that affect long-term viability of… Expand
Conservation and Use of Rice Germplasm : an Evolving Paradigm under the International Treaty on Plant Genetic Resources for Food and Agriculture
  • 2008
This document was commissioned by the FAO, as a contribution to the work of the Twentieth Session of the International Rice Commission. The opinions expressed in the document are those of theExpand
Influence of ethnic traditional cultures on genetic diversity of rice landraces under on-farm conservation in southwest China
TLDR
On-farm conservation can effectively promote the allelic variation and increase the genetic diversity of rice landraces over the past 35 years, and ethnic traditional cultures play a positive influence on rice landrace variety diversity and genetic diversity. Expand
Genetic association analysis of indica rice yield and related traits in irrigated ecosystems
TLDR
The results indicated that IRRI breeding lines with stable and good performance in the WS could be used in SC (directly as varieties or as parental lines in breeding) and that selection is better done in the DS in IRRI for use in JX, China. Expand
Recent progress on the genetics and molecular breeding of brown planthopper resistance in rice
TLDR
The increasing number of fine-mapped and cloned genes provide a solid foundation for development of functional markers for use in breeding of brown planthopper resistance, and prospects for developing cultivars with durable, broad-spectrum BPH resistance are discussed. Expand
Germplasm and Genetic Diversity Studies in Rice for Stress Response and Quality Traits
TLDR
This chapter focuses on the above-said traits along with the potential benefits for researchers who are involved in rice, for farmer’s food security and livelihoods, and also provides a thorough understanding of genetic diversity, population structure, and familial relatedness necessary for rice breeding program. Expand
A marker-based approach to broadening the genetic base of rice in the USA
TLDR
The genetic diversity of 236 rice accessions was investigated on the basis of genotypic evaluation at 113 restriction fragment length polymorphism (RFLP) and 60 simple sequence repeat (SSR) loci and significant differences in allele frequencies were observed between the world and U.S. collections. Expand
Assessment of the Genetic Diversity in Argentine Rice Cultivars with SSR Markers
TLDR
Genetic diversity of rice (Oryza sativa L.) cultivars that are historically significance to rice breeding and production in Argentina were evaluated at the DNA level, generating a database useful for cultivar identification, local germplasm conservation, and breeding programs. Expand
Tagging and mapping of genes and QTLs of Nilaparvata lugens resistance in rice
TLDR
The most recent data on the N. lugens resistance rice varieties is presented, missing information is highlighted that could help to design better N. Lugens resistant varieties, and the significance of the data presented for the future of rice breeding is evaluated. Expand
Genetic diversity within Oryza rufipogon germplasms preserved in Chinese field gene banks of wild rice as revealed by microsatellite markers
TLDR
High polymorphisms of rice microsatellite loci and their great resolving power will be particularly helpful for germplasm evaluation and evolutionary studies for better strengthening the conservation and utilization of genetic diversity of wild rice in the field gene banks. Expand
Genetic diversity of rice germplasm used in Taiwan breeding programs
TLDR
DNA polymorphism analysis revealed genomic relationships in Taiwan rice germplasm, and the database on ‘The Resource of Rice Genetic Markers in Taiwan' is useful for cultivar identification, local germplasms conservation and breeding programs. Expand
