Article Synopsis
- Plant genetic resources (PGR) in genebanks serve as crucial assets for future crop diversity, especially in breeding programs.
- Genotyping and whole-genome shotgun sequencing were applied to large samples of winter wheat PGR and modern cultivars to identify traits and improve resistance to threats like yellow rust.
- The integration of genomic and phenotypic data promises to enhance breeding strategies, providing better insights into PGR's potential contributions to crop yield and adaptation.
Article Synopsis
- The text discusses the importance of maintaining genetic diversity in genebanks for future crop improvement, specifically focusing on wheat.
- It outlines a new strategy that utilizes genomic data to enhance wheat breeding by incorporating nonadapted germplasm and identifying useful genetic traits.
- The study found potential sources of resistance to yellow rust and determined that crosses between elite cultivars and plant genetic resources can lead to higher yields in field trials.
Reciprocal recurrent genomic selection is a breeding strategy aimed at improving the hybrid performance of two base populations. It promises to significantly advance hybrid breeding in wheat. Against this backdrop, the main objective of this study was to empirically investigate the potential and limitations of reciprocal recurrent genomic selection.

The expression of known resistance genes starts at different developmental stages of wheat. Breeding for resistance can be supported by a fast, precise, and resource-saving phenotyping.

Beta species show a wide variation of bolting time regarding the year of first reproduction, seasonal bolting time and the number of reproduction cycles. To elucidate the genetics of bolting time control, we used three F mapping populations that were produced by crossing a semelparous, annual sugar beet with iteroparous, vernalization-requiring wild beet genotypes.

This study reveals for the first time a major QTL for post-winter bolting resistance in sugar beet ( Beta vulgaris L.). The knowledge of this QTL is a major contribution towards the development of a winter sugar beet with controlled bolting behavior.
