Abstract

Key message

Next-generation sequencing (NGS) has revolutionized plant and animal research by providing powerful genoty** methods. This review describes and discusses the advantages, challenges and, most importantly, solutions to facilitate data processing, the handling of missing data, and cross-platform data integration.

Abstract

Next-generation sequencing technologies provide powerful and flexible genoty** methods to plant breeders and researchers. These methods offer a wide range of applications from genome-wide analysis to routine screening with a high level of accuracy and reproducibility. Furthermore, they provide a straightforward workflow to identify, validate, and screen genetic variants in a short time with a low cost. NGS-based genoty** methods include whole-genome re-sequencing, SNP arrays, and reduced representation sequencing, which are widely applied in crops. The main challenges facing breeders and geneticists today is how to choose an appropriate genoty** method and how to integrate genoty** data sets obtained from various sources. Here, we review and discuss the advantages and challenges of several NGS methods for genome-wide genetic marker development and genoty** in crop plants. We also discuss how imputation methods can be used to both fill in missing data in genotypic data sets and to integrate data sets obtained using different genoty** tools. It is our hope that this synthetic view of genoty** methods will help geneticists and breeders to integrate these NGS-based methods in crop plant breeding and research.
