“…Tolerance to cold at the booting stage is one of the most genetically complex traits in rice. To date, about 40 quantitative trait loci (QTLs) located on all chromosomes have been reported in various cross combinations (Andaya and Mackill 2003, Dai et al 2004, Kuroki et al 2007, Li et al 1997, Oh et al 2004, Saito et al 1995, Suh et al 2010, Takeuchi et al 2001, Xu et al 2008. Detection of QTLs with large effects has made it possible to transfer the target QTL (or gene) into elite varieties by marker-assisted selection (MAS); however, breeding for cold tolerance has been mainly by artificial selection with conventional breeding methods because of its complex pattern of inheritance.…”

Cold stress at the booting stage in rice induces spikelet sterility because of aberrant microspore development, which often seriously damages seed production. Some breeding lines with high cold tolerance were developed by using tropical japonica variety Silewah as a donor of cold tolerance; however, the genetic factors that confer cold tolerance of this variety have not been comprehensively analyzed. In this study, phenotypic and molecular characterization of novel cold-tolerant strains derived from crosses with Silewah was performed to identify quantitative trait loci (QTLs) responsible for cold tolerance. Molecular marker analysis revealed that 2 cold-tolerant strains carried chromosomal segments of Silewah at the same genomic regions on chromosomes 3, 4 and 11. Single marker analysis in segregating population confirmed that the allele of Silewah on chromosome 3 (qCTB3-Silewah) conferred cold tolerance. The effect of qCTB3-Silewah was supported by the fact that this allele had been a target of selection during developing a breeding line by phenotypic selection from backcrossed progenies with an elite variety as a recurrent parent. qCTB3 is a different QTL from those reported for Silewah previously, suggesting that different QTLs might be exploited in different breeding programs depending on the genetic backgrounds and environmental conditions.

“…QTL mapping studies for cold tolerance at booting stage have also been conducted on various rice populations (Andaya and Mackill 2003;Dai et al 2004;Li et al 1997Li et al , 2003Saito et al 2004Saito et al , 2001Saito et al , 1995Takeuchi et al 2001;Xu et al 2008). Saito et al (1995) mapped two QTLs for cold tolerance at the booting stage in Norin-PL8 on chromosomes 3 and 4.…”

Low temperature is a major abiotic stress for rice cultivation, causing serious yield loss in many countries. To identify QTL controlling low temperature induced spikelet sterility in rice, the progeny of F2, BC1F1 and BC2F1 populations derived from a Reiziq 9 Lijiangheigu cross were exposed to 21/15°C for 15 days at the booting stage, and spikelet sterility was assessed. For genotyping, 92 polymorphic markers from 373 SSR and 325 STS primer pairs were used. A major QTL was initially indentified on the short arm of chromosome 10 by selective genotyping using highly tolerant and susceptible progeny from F2 and BC1F1 populations. The QTL (qLTSPKST10.1) was validated and mapped by genotyping the entire F2 (282 progeny) and BC1F1 (84 progeny) populations.The results from the F2 population showed that qLTSPKST10.1 could explain 20.5% of the variation in spikelet sterility caused by low temperature treatment with additive (a = 14.4) and dominant effect (d = -7.5). From the analysis of 98 selected BC2F1 progeny, the QTL located in the 3.5 cM interval between S10010.9 and S10014.4 was further confirmed. Based on the studies of 3 generations in 2 years, it was clear that the QTL on chromosome 10 is a major determinant of the control of low temperature induced spikelet sterility at booting stage.

“…Takeuchi et al (2001) identified three QTLs in a cross between two japonicas; one of the QTLs on chromosome 7 contributed 22% to the phenotypic variation. Dai et al (2004) also detected a strong QTL on chromosome 7 from a Yunnan land race. Another QTL on chromosome 4 was detected by introgressing the chromosomal fragment from the tolerant tropical japonica Silewah into the japonica variety Hokkai241.…”

Abstract:The status of rice as a model crop and the sequencing of the indica and japonica genomes have provided breeders with the necessary tools for marker assisted breeding. Simple Sequence Repeat (SSR) markers are easily available for any region of the genome, and candidate gene markers are being developed rapidly. The likely targets of MAS include yield and agronomic traits, cooking and nutritional quality, and resistances to abiotic and biotic stresses. MAS for gene pyramiding for disease and insect resistances is being widely used. For major genes and QTLs of larger effect, marker assisted backcrossing (MAB) is an effective method for developing improved versions of widely-grown "mega" varieties. Developing submergence tolerant mega varieties is a good example of how the MAB approach can result in significantly improved mega varieties within two to three years. The use of markers in more conventional breeding nurseries has been limited by cost, but is beginning to be applied for some traits like grain quality. Lower-cost marker methods combined with large-scale gene discovery will increase the use of MAS over the next decade.
