Article Synopsis
- Genetic gain in Nordic spring barley varieties is 1.07% per year, which highlights the importance of continuous yield improvement for this essential European crop.
- The study used historical data from 2014 to 2022 to analyze genetic gains and assessed the effectiveness of genomic prediction (GP) by testing 375 breeding lines across multiple environments from 2019 to 2022.
- The results showed a genomic predictive ability of 0.61 for yield, indicating that GP can be a valuable tool in barley breeding programs and offers a potential advantage over traditional breeding methods.
Article Synopsis
- - Faba bean is a globally cultivated legume that shows promise for increasing plant-based protein production, which is essential for sustainable food systems.
- - A study involving 220 faba bean varieties aimed to assess phenotypic diversity, analyze the effects of breeding on traits, and identify genetic markers through a genome-wide association study (GWAS).
- - The research found significant genetic variation for key traits, demonstrated correlations between yield and certain agronomic factors, and discovered novel genetic markers linked to flowering time and other traits, highlighting the impact of breeding on the crop.
Genomic selection, the application of genomic prediction (GP) models to select candidate individuals, has significantly advanced in the past two decades, effectively accelerating genetic gains in plant breeding. This article provides a holistic overview of key factors that have influenced GP in plant breeding during this period. We delved into the pivotal roles of training population size and genetic diversity, and their relationship with the breeding population, in determining GP accuracy.

Development of viable pollen and its timely release from the anther are essential for fertilisation of angiosperm flowers. The formation and subsequent dehiscence of the anther are under tight regulatory control, and these processes are remarkably conserved throughout the diverse families of the angiosperm clade.
