GWAS revealed effect of genotype × environment interactions for grain yield of Nebraska winter wheat.

Background: Improving grain yield in cereals especially in wheat is a main objective for plant breeders. One of the main constrains for improving this trait is the G × E interaction (GEI) which affects the performance of wheat genotypes in different environments. Selecting high yielding genotypes that can be used for a target set of environments is needed.

Genetic Diversity and Population Structure of F Nebraska Winter Wheat Genotypes Using Genotyping-By-Sequencing.

The availability of information on the genetic diversity and population structure in wheat ( L.) breeding lines will help wheat breeders to better use their genetic resources and manage genetic variation in their breeding program. The recent advances in sequencing technology provide the opportunity to identify tens or hundreds of thousands of single nucleotide polymorphism (SNPs) in large genome species (e.
