“…Siangliw et al (2003) also found that the SUB1 introgression lines of KDML105, the Thai jasmine variety, had the same aroma and high cooking quality (soft-cooking character) as the original KDML105. The results of the experiments conducted with SwarnaSub1 showed that the introgression of SUB1 did not have any major negative effects on grain quality under normal conditions Mackill et al, 2006;Sarkar et al, 2006;Neeraja et al, 2007). The color difference between Swarna and Swarna-Sub1 kernels was due to the inhibition of brown furrows in the seed coat of Swarna-Sub1, yielding plants with straw-colored hulls instead of the golden color of Swarna, which is the result of a linkage between the SUB1 locus and the gene Inhibitor of Brown furrows (IBf) located in the same region on chromosome 9 (Ideta et al, 1995;Neeraja et al, 2007).…”

“…It is therefore now essential, not only to grow more high quality rice per hectare, but also to equip these varieties with tolerance to environmental stresses (Brar and Khush, 2013). To this end, significant investment has been made in many countries to improve yield and stress tolerance, while retaining quality (Singh et al, 2000;Inthapanya et al, 2006;Mackill et al, 2006;Tomita, 2009;Boualaphanh et al, 2011). The current tools of quality evaluation are not sophisticated enough to define the quality each market requires, let alone enable selection for it.…”

“…Furthermore, recombinant selection can minimize the size of the donor chromosome segment, thus reducing “linkage drag”—a “universal enemy” of the plant breeder [115]. This approach has been widely used and, due to the prevalence of several rice “mega varieties,” it is likely to continue being a successful approach [118]. …”

Using DNA markers in plant breeding with marker-assisted selection (MAS) could greatly improve the precision and efficiency of selection, leading to the accelerated development of new crop varieties. The numerous examples of MAS in rice have prompted many breeding institutes to establish molecular breeding labs. The last decade has produced an enormous amount of genomics research in rice, including the identification of thousands of QTLs for agronomically important traits, the generation of large amounts of gene expression data, and cloning and characterization of new genes, including the detection of single nucleotide polymorphisms. The pinnacle of genomics research has been the completion and annotation of genome sequences for indica and japonica rice. This information—coupled with the development of new genotyping methodologies and platforms, and the development of bioinformatics databases and software tools—provides even more exciting opportunities for rice molecular breeding in the 21st century. However, the great challenge for molecular breeders is to apply genomics data in actual breeding programs. Here, we review the current status of MAS in rice, current genomics projects and promising new genotyping methodologies, and evaluate the probable impact of genomics research. We also identify critical research areas to “bridge the application gap” between QTL identification and applied breeding that need to be addressed to realize the full potential of MAS, and propose ideas and guidelines for establishing rice molecular breeding labs in the postgenome sequence era to integrate molecular breeding within the context of overall rice breeding and research programs.
