About this Research Topic
Selection is the main goal of plant breeders and geneticists to genetically improve target traits in cereal crops. Resistance to plant disease depends on selecting highly resistant genotypes that should be used for a future breeding program to produce cultivars with higher disease resistance. Therefore, the selection is a very critical stage and should be performed precisely. However, phenotypic selection alone can be misleading because it depends on the precision of the human scorer. Most of the traditional selection methods are entirely based on phenotypic selection.
Recent advances in genetic analyses in plant breeding such as genome-wide association study and QTL mapping have paved the way to identify candidate genes associated with target traits. Such genetic association analyses provide significant DNA markers associated with increased resistance. The selected genotypes with the highest number of favorable resistant alleles will promise a fruitful selection that can be utilized to genetically produce highly resistant cultivars through molecular breeding programs.
Many studies reported highly resistant genotypes for disease resistance based on phenotypic data. Others reported highly significant markers detected by genetic association analyses without shedding light on the presence of favorable alleles in the highly resistant genotypes if they are mentioned. This Research Topic aims to present a set of novel research studies that utilize the outputs of QTL and GWAS analysis and phenotypic selection for highly resistant genotypes to investigate the number of favorable alleles that are associated with increased resistance in each selected genotype.
This topic will cover many studies that will present the results of genetic association analyses such as genome-wide association studies, QTL mapping, etc. along with precise phenotypic for disease resistance in cereal crops. From this perspective, we hope to receive manuscripts that include the selection of the most promising disease-resistant genotypes with highly favourable resistant alleles that can be detected by any genetic association method.
