Rice-QTL-Marker Database - A breeder friendly resource tool for easy deployment of markers for selection of complex traits in rice (Oryza sativa L.)

Abstract

Rice was chosen as a model organism for genome sequencing because of its economic and utility value, small genome size, and syntenic relationship with other cereal species. Many genes rather than a single locus often influence several economically important traits, that are known as quantitative trait loci (OTl). Ouantitative trait locus is a polymorphic locus which contains alleles that differentially affect the expression of a continuously distributed phenotypic trait. OTl mapping is a useful approach for detection of complex traits in crops, evolution and medicine, molecular dissection of quantitative phenotypes, supplementing the principles of classical quantitative genetics. This has accelerated the progress in the manipulation of plant and animal genomes [1].
