Article Synopsis
- Crop wild relatives are important for improving crops by providing genetic traits that help with climate change and disease resilience.
- Research on sunflowers revealed that while introgressing wild genes can introduce beneficial genetic diversity, it often negatively affects yield and quality due to linkage drag.
- The study suggests that breeding should prioritize closely related wild relatives to minimize adverse effects while enhancing desirable traits in cultivated sunflowers.
High-throughput genotyping of large numbers of lines remains a key challenge in plant genetics, requiring geneticists and breeders to find a balance between data quality and the number of genotyped lines under a variety of different existing genotyping technologies when resources are limited. In this work, we are proposing a new imputation pipeline ("HBimpute") that can be used to generate high-quality genomic data from low read-depth whole-genome-sequence data. The key idea of the pipeline is the use of haplotype blocks from the software HaploBlocker to identify locally similar lines and subsequently use the reads of all locally similar lines in the variant calling for a specific line.
