- Abstract:
- ... KEY MESSAGE: In the soybean cultivar Suweon 97, BCMV-resistance gene was fine-mapped to a 58.1-kb region co-localizing with the Soybean mosaic virus (SMV)-resistance gene, Rsv1-h raising a possibility that the same gene is utilized against both viral pathogens. Certain soybean cultivars exhibit resistance against soybean mosaic virus (SMV) or bean common mosaic virus (BCMV). Although several SMV-r ...

- Abstract:
- ... KEY MESSAGE: Wheat cultivar Madsen has a new gene on the short arm of chromosome 1A and two QTL for all-stage resistance and three QTL for high-temperature adult-plant resistance that in combination confer high-level, durable resistance to stripe rust. Wheat cultivar Madsen has maintained a high-level resistance to stripe rust over 30 years. To map quantitative trait loci (QTL) underlying the high ...

- Abstract:
- ... Spinach is a popular vegetable native to central and western Asia. It is dioecious with a pair of nascent sex chromosomes. The difficulties of working with the non-recombining sex determination region of XY individuals have hindered the progress toward sequencing sex chromosomes of most dioecious species. Here we present important advances toward characterizing the non-recombining sex chromosomes ...

KEY MESSAGE: Exploitation of data from a ryegrass breeding program has enabled rapid development and implementation of genomic selection for sward-based biomass yield with a twofold-to-threefold increase in genetic gain. Genomic selection, which uses genome-wide sequence polymorphism data and quantitative genetics techniques to predict plant performance, has large potential for the improvement in ...

Identification of quantitative trait loci (QTL) for yield-related traits and closely linked molecular markers is important in order to identify gene/QTL for marker-assisted selection (MAS) in wheat breeding. The objectives of the present st ...

Capana02g002096 encodes a homolog of AtDYT1 which is a bHLH transcription factor and involves in the early tapetal development. Genic male-sterile line is an efficient tool for commercial hybrid seed production in pepper; however, so far, only few genes controlling this trait have been ...

- Abstract:
- ... Key Message Powdery mildew resistance in two strawberry mapping populations is controlled by both stable and transient novel QTL of moderate effect. Some low transferability of QTL across wider germplasm was observed. The obligate biotrophic fungus Podosphaera aphanis is the causative agent of powdery mildew on cultivated strawberry (Fragaria × ananassa). Genotypes from two bi-parental mapping pop ...

KEY MESSAGE: We have elucidated the Andigena origin of the potato Ryₐdg gene on chromosome XI of CIP breeding lines and developed two marker assays to facilitate its introgression in potato by marker-assisted selection. Potato virus Y (PVY) is causing yield and quality losses forcing farmers to renew periodically their seeds from clean stocks. Two loci for extreme resistance to PVY, one on chromos ...

KEY MESSAGE: The major QTL for FHB resistance from hexaploid wheat line PI 277012 was successfully introgressed into durum wheat and minor FHB resistance QTL were detected in local durum wheat cultivars. A combination of these QTL will enhance FHB resistance of durum wheat. Fusarium head blight (FHB), caused by Fusarium graminearum, is a devastating disease of durum wheat. To combat the disease, g ...

- Abstract:

It achieves this by optimising efficiency of converting genetic diversity into genetic gain through reducing the loss of genetic diversity and reducing the drop of genomic prediction accuracy with rapid cycling. This study evaluates optimal cross selection to balance se ...

- Abstract:
- ... The domesticated gene Q on wheat chromosome 5A (5AQ) encodes an AP2 transcription factor. The 5AQ was originated from a G to A mutation in exon 8 and/or C to T transition in exon 10 and resulted in free-threshing and subcompact spike characters of bread wheat. The Q homeoalleles on 5B and 5D are either a pseudogene or expressed at a low level. Our previous study identified a mutant, named NAUH164, ...

SNPs in genic regions did not improve prediction accuracy compared to SNPs in intergenic regions. Since genotyping can represent an important cost in genomic selection, it is important to minimize it without compromising the accuracy of predictions. The objectives of the present study we ...
