Research ArticleOpen accessEvery word in the titleQTL Mapping Using Multiple Markers SimultaneouslyD. Kolbehdari, J.A.B. RobinsonMethods for detecting and locating a single QTL within a 10 cM region of DNA using 10 equally spaced SNP markers were compared. The QTL was assumed to be bi-allelic and located between markers 5 and 6. Monte Carlo simulation of a granddaughter design with 30 sires and 400 sons was used. Linear regression nested within sire using either two … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 7,110 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleMapping QTLs Linked to Physio-Morphological and Plant Production Traits under Drought Stress in Rice (Oryza sativa L.) in the Target EnvironmentS. Michael Gomez, S. Satheesh Kumar, P. Jeyaprakash et al.Drought stress is a major constraint for rice (Oryza sativa L.) production and yield stability in rainfed ecosystems. Identifying genomic regions (QTLs) contributing in drought resistance will help to develop rice cultivars suitable for water-limiting environments through marker-assisted breeding. QTLs linked to physio-morphological and plant production traits under drought stress in the field were mapped by evaluating 177 F6 recombinant … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 4 · 31 Dec 2006 · 14,471 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleIntrogression the SalTol QTL into the Elite Rice Variety of Russia by Marker-Assisted SelectionAlexander Vyacheslavovich Usatov, Andrey Vasilevich Alabushev, Pavel Ivanovich Kostylev et al.The present work is devoted to investigation of the possibility to apply methods of Marker-Assisted Selection (MAS) to introgression the SalTol QTL into genotypes of elite Russian varieties of rice. It was shown that microsatellite markers Rm493, may be effectively used to control transfer the SalTol QTL genes into Russian populations of rice. Based on the highly productive variety “Novator”, … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 4 · 18 Nov 2015 · 9,259 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsQuantitative Trait Loci Analysis of Novel Fusarium Head Blight Resistance in Tokai 66Y. Yen, A.M. H. Ibrahim, S. Malla et al.Problem Statement: Identification of Quantitative Trait Loci (QTLs) in durable resistant genotype is important for marker-assisted breeding. The study was conducted to identify QTLs linked to FHB resistance in 'Tokai 66', a Japanese genotype. Approach: A cross was made between Tokai 66 and Jagalene and the single seed descend was used to advance the population. The F2:4 and F2:5 populations … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 8,091 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsGenome-Wide Association Study of Single Nucleotide Polymorphisms with Milk Traits in Red Gorbatov CattleMarina Ivanovna Selionova, Grigorii Sergeyevich Shekhovtsev, Ivan Petrovich Prokhorov et al.In order to preserve the gene pool of the Red Gorbatov breed, it is necessary to use a set of genomic analysis tools that allows more efficient planning in obtaining individuals who meet the economic requirements of dairy farming. The aim of the work was to identify candidate genes associated with milk production traits in Red Gorbatov cattle using a … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 4 · 12 Oct 2024 · 4,736 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhysiological and Molecular-Genetic Evaluation of Rice Breeding Resources on Cold Tolerance for Creating New Varieties for the Northern Zone of Rice CultivationYeldos Almabekovich Zhanbyrbayev, Aiman Bokenovna Rysbekova, Bakdaulet Naubaevich Usenbekov et al.This study was aimed at assessing cold tolerance of rice breeding materials produced in Kazakhstan and foreign countries in the phase of seed germination, creating initial cold-tolerant forms and lines to derive Kazakhstan varieties of rice and identifying in the selection material the genes of the quantitative loci of cold tolerance (qPSST-3, qPSST-7 and qPSST-9), based on the molecular-genetic approach. … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 23 Sep 2017 · 7,416 accessesView PDF Cite

Research ArticleOpen accessIn the abstractValidation of SSR markers associated with Submergence Tolerance in Rice (Oryza sativa L.)Kirill V. Azarin, Alexander V. Usatov, Andrey V. Alabushev et al.The present work is devoted to the validation of SSR markers associated with submergence tolerance (Sub1A) QTLs in rice. It was shown that only microsatellite markers RM 7481 differentiates donor lines and recipient variety. Based upon the results of DNA analysis with the marker of the RM 7481 of the F2-plants, the 14 homozygotes by the locus Sub1A, 40 samples … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 19 Dec 2016 · 7,634 accessesView PDF Cite
