This proposal will develop a cost effective genotyping-by-sequencing (GbS) method
which will target specific markers and is highly flexible in the number of markers that can be
genotyped on a soybean line. In addition, because specific SNPs are targeted, the missing data
rate will be lower than 10% which is a significant improvement over current GbS methods. This
eliminates the need for imputation and for the development of novel methods to detect
heterogeneity. Genotyping soybean pollen to determine recombination rates both across the
genome and within specific regions has never been reported. This will provide a unique tool for
UNL soybean researchers to study recombination in soybean and will provide the foundation for
a future proposal to NSF to study how stress to plants affects recombination.
