Genomic selection (GS) is a new breeding method that makes use of genome-wide DNA marker data to improve the efficiency of breeding for quantitative traits. In GS, individuals with superior breeding...Jennifer SpindelJoint Genome InstituteHiroyoshi Iwata...
3.1. GS application in pure line selection GS technology can be used for inbred selection as well as hybrid breeding in rice. Currently, GS studies in rice mainly focus on designing a training population and evaluating the predictive ability within or between populations. In rice breeding populatio...
Assessing the performance of elite lines in target environments is essential for breeding programs to select the most relevant genotypes. One of the main complexities in this task resides in accounting for the genotype by environment interactions. Genomi
The role of rice genomics in breeding progress is becoming increasingly important. Deeper research into the rice genome will contribute to the identification and utilization of outstanding functional genes, enriching the diversity and genetic basis of breeding materials and meeting the diverse dema...
Rapeseed (Brassica napus L.) is an important oil-producing crop for the world. Its adaptation, yield and quality have been considerably improved in recent decades, but the genomic basis underlying successful breeding selection remains unclear. Hence, we
we identified 20 loci of very strong selection under recent breeding (Supplementary Fig. 8andSupplementary Tables 5 and 6). We found that there are no overlaps between the genetic-improvement sweeps inindicaand those injaponica, suggesting that few introgression events between the two subspecies occ...
Genome wide association (GWA) studies demonstrate linkages between genetic variants and traits of interest. Here, we tested associations between single nucleotide polymorphisms (SNPs) in rice (Oryza sativa) and two root hair traits, root hair length (RHL
Conventional breeding, marker-assisted selection, genomic selection and inbreeding in clonally propagated crops: a case study for cassava Consolidates relevant molecular and phenotypic information on cassava to demonstrate relevance of heterosis, and alternatives to exploit it by integrating ...

Some chromosomal regions had highly skewed allele frequencies, suggesting that regions associated with high-yielding phenotypes had been conserved during the process of breeding selection. GWAS is undoubtedly an effective way to detect QTLs, but is not very useful for a population consisting of ...
The rich genetic diversity in Oryza sativa and Oryza rufipogon serves as the main sources in rice breeding. Large-scale resequencing has been undertaken to discover allelic variants in rice, but much of the information for genetic variation is often lost
