BackgroundDeveloping new population types based on interspecific introgressions has been suggested by several authors to facilitate the discovery of novel allelic sources for traits of agronomic importance. Chromosome segment substitution lines from interspecific crosses represent a powerful and useful genetic resource for QTL detection and breeding programs.ResultsWe built a set of 64 chromosome segment substitution lines carrying contiguous chromosomal segments of African rice Oryza…

Chromosome Segment Substitution Lines: A Powerful Tool for the Introgression of Valuable Genes from Oryza Wild Species into Cultivated Rice (O. sativa)

An overview of the research involving CSSLs and BILs in the introgression of quantitative trait loci (QTLs) associated with the improved performance of rice including resistance to various biotic and abiotic stresses, and even high yield from wild relatives of rice and other unadapted germplasm into the genetic background of adapted rice cultivars is presented.

Identification and Fine Mapping of Pi69(t), a New Gene Conferring Broad-Spectrum Resistance Against Magnaporthe oryzae From Oryza glaberrima Steud

Evaluation of IL106 with 151 blast strains collected from 6 countries in Asia showed that 148 strains are avirulent on IL106, suggesting that Pi69(t) is a broad-spectrum blast R gene, and a promising resistant resource for improvement of Asian cultivated rice.

Construction of a new set of rice chromosome segment substitution lines and identification of grain weight and related traits QTLs

A new set of chromosome segment substitution lines (CSSLs) in rice, in which the genome of the elite japonica cultivar C418 has been introgressed into the background of the Elite indica cultivar 9311, was developed by marker aided selection.

Development of introgression lines of AA genome Oryza species, O. glaberrima, O. rufipogon, and O. nivara, in the genetic background of O. sativa L. cv. Taichung 65

Three sets of CSSLs carrying segments of AA genome species closely related to Oryza sativa are developed through the use of 101 to 121 simple-sequence-repeat markers in whole-genome genotyping and marker-assisted selection.

Introgression Lines: Valuable Resources for Functional Genomics Research and Breeding in Rice (Oryza sativa L.)

The narrow base of genetic diversity of modern rice varieties is mainly attributed to the overuse of the common backbone parents that leads to the lack of varied favorable alleles in the process of…

Development and exploitation of a set of contiguous segmental substitution lines in pearl millet[Pennisetum glaucum (L.) R. Br.]

The present results validate these QTLs which were detected in earlier studies using testcrosses of an advanced backcross population derived from two agronomically elite parental lines and provide a nearly ideal set of genetic stocks for fine mapping the multitude of traits for which their parents differ, and use in unraveling the genetic and physiological mechanisms of several agronomeically important but complexly inherited traits.

Genetic characterization and fine mapping of qHMS4 responsible for pollen sterility in hybrids between Oryza sativa L. and Oryza glaberrima Steud

QTL mapping and introgression of yield-related traits from Oryza glumaepatula to cultivated rice (Oryza sativa) using microsatellite markers

Positive QTL effects from O. glumaepatula were observed in chromosomal regions associated with tillering and panicle-number traits, and could be a source of alleles of agronomic importance to rice breeding programs.

Construction of introgression lines carrying wild rice (Oryza rufipogon Griff.) segments in cultivated rice (Oryza sativa L.) background and characterization of introgressed segments associated with yield-related traits

It is revealed that the high-yielding and low-Yielding ILs contained relatively less introgressed segments than the low-y yielding ILs, and that the yield increase or decrease was mainly due to the number of grain.

A wide population consisting of 217 chromosome single-segment substitution lines (SSSLs) using HJX74, an elite Indica cultivar, as recipient, and 6 other accessions, including 2 Indica and 4 Japonica, as donors is developed to facilitate the genetic analysis of complex traits and the use of marker-assisted breeding in rice.

The reciprocal substitution set appeared to be an efficient and systematic method for QTL precision analysis and consistent reciprocal QTL effects for heading date and grain size were observed in both IAS and AIS.

Assessing hybrid sterility in Oryza glaberrima × O. sativa hybrid progenies by PCR marker analysis and crossing with wide compatibility varieties

Monitoring of reproductive plant development showed that spikelet sterility was at least partially due to an arrest of pollen development at the microspore stage, which suggests that distinct or additional S-loci are responsible for sterility of O. glaberrima × O. sativa indica hybrids.

RFLP analysis of rice (Oryza sativa L.) introgression lines

None of the RFLP markers could be unambiguously associated with BPH resistance, and some of the introgressed segments show association with genes for brown planthopper (BPH) resistance in some introgression lines, but not in others.
