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, inclu...

A number of different marker-assisted selection (MAS) approaches do exist for the improvement of polygenic traits. Results of a marker-assisted backcross (MABC) selection experiment aimed at improving grain yield under drought conditions in tropical maize are presented and compared with alternative MAS strategies. The introgression of favourable alleles at five target regions involved in the ex...

Bacterial halo blight (BHB) is a bacterial disease, caused by Pseudomonas syringae pv. garcae, which has been gaining prominence in the main coffee-producing regions. Chemical control of this disease increases production costs and environmentally undesirable. In scenario, development new cultivars resistant to BHB most economical sustainable alternative. Marker-Assisted Selection (MAS) an appro...

Many factors have contributed to the inability to successfully employ a marker-based selection scheme for The advent of high throughput molecular technologies has led to complex traits. One major difficulty has been the effecan expectation that breeding programs will use marker–trait associations to conduct marker-assisted selection (MAS) for traits. Many tive detection, estimation, and utility...

Marker-Assisted-Selection (MAS) is mainly important in situations, where the current accuracy of selection is low, e.g. traits with low heritability, limited, late-in-life, or afterslaughter recording. In veloand whizzo genetics schemes, the number of selection cycles per time period is minimized, which may increase rates of genetic gain dramatically. Genomic selection is used to obtain a high ...

Genetic maps are particularly important and valuable tools for quantitative trait locus (QTL) mapping and marker assisted selection (MAS) of plant with desirable traits. In this study, 173 F1 plants from a cross between Mangifera indica L. "Jin-Hwang" and M. indica L. "Irwin" and their parent plants were subjected to high-throughput sequencing and specific-locus amplified fragment (SLAF) librar...

Background In last decades, the progress of molecular techniques, bioinformatics tools and genome analysis equipment allowed genomes to be sequenced and analyzed for several plants. For Eucalyptus, the combination of quantitative trait loci (QTL) mapping with genomic analyses, has allowed the identification and validation of a few genomic regions involved in growth and wood quality characters. ...

A major objective of quantitative trait loci (QTL) studies is to find genes/markers that can be used in breeding programs via marker assisted selection (MAS). From an extensive review, we surveyed the distribution of QTL for yield and yield-related traits on wheat genome. In order to identify the important regions involving in these traits, QTL meta-analysis was performed. As a result, 55 MQTL ...

Rice, as one of the staple food crops in world, is reduced by 10~30% every year due to damage rice blast. However, application marker assistant selection (MAS) with disease resistance genes can be effectively, accurately and rapidly used breed blast resistant varieties. The gene  Pi-k h  has been proved have broad-spectrum blast. Therefore, utilization of   gene MA...
