Abstract

To ensure the nutritional needs of an expanding global population, it is crucial to optimize the growing capabilities and breeding values of fruit and vegetable crops. While genomic selection, initially implemented in animal breeding, holds tremendous potential, its utilization in fruit and vegetable crops remains underexplored. In this systematic review, we reviewed 63 articles covering genomic selection and its applications across 25 different types of fruit and vegetable crops over the last decade. The traits examined were directly related to the edible parts of the crops and carried significant economic importance. Comparative analysis with WHO/FAO data identified potential economic drivers underlying the study focus of some crops and highlighted crops with potential for further genomic selection research and application. Factors affecting genomic selection accuracy in fruit and vegetable studies are discussed and suggestions made to assist in their implementation into plant breeding schemes. Genetic gain in fruits and vegetables can be improved by utilizing genomic selection to improve selection intensity, accuracy, and integration of genetic variation. However, the reduction of breeding cycle times may not be beneficial in crops with shorter life cycles such as leafy greens as compared to fruit trees. There is an urgent need to integrate genomic selection methods into ongoing breeding programs and assess the actual genomic estimated breeding values of progeny resulting from these breeding programs against the prediction models.

用于改良水果和蔬菜作物的基因组选择:系统性范围审查
为确保不断增长的全球人口的营养需求,优化果蔬作物的生长能力和育种价值至关重要。基因组选择最初应用于动物育种,具有巨大的潜力,但其在果蔬作物中的应用仍未得到充分探索。在这篇系统性综述中,我们回顾了过去十年中涉及基因组选择及其在 25 种不同类型果蔬作物中应用的 63 篇文章。所研究的性状与作物的食用部分直接相关,具有重要的经济意义。与世界卫生组织/粮农组织数据的比较分析确定了一些作物研究重点的潜在经济驱动因素,并强调了具有进一步基因组选择研究和应用潜力的作物。本文讨论了影响水果和蔬菜研究中基因组选择准确性的因素,并提出了一些建议,以帮助在植物育种计划中实施基因组选择。利用基因组选择来提高选择强度、准确性和遗传变异的整合,可以提高水果和蔬菜的遗传增益。然而,与果树相比,缩短育种周期对于叶菜类等生命周期较短的作物可能并无益处。目前迫切需要将基因组选择方法纳入正在进行的育种计划,并根据预测模型评估这些育种计划产生的后代的实际基因组估计育种值。

期刊介绍: Molecular Breeding is an international journal publishing papers on applications of plant molecular biology, i.e., research most likely leading to practical applications. The practical applications might relate to the Developing as well as the industrialised World and have demonstrable benefits for the seed industry, farmers, processing industry, the environment and the consumer. All papers published should contribute to the understanding and progress of modern plant breeding, encompassing the scientific disciplines of molecular biology, biochemistry, genetics, physiology, pathology, plant breeding, and ecology among others. Molecular Breeding welcomes the following categories of papers: full papers, short communications, papers describing novel methods and review papers. All submission will be subject to peer review ensuring the highest possible scientific quality standards. Molecular Breeding core areas: Molecular Breeding will consider manuscripts describing contemporary methods of molecular genetics and genomic analysis, structural and functional genomics in crops, proteomics and metabolic profiling, abiotic stress and field evaluation of transgenic crops containing particular traits. Manuscripts on marker assisted breeding are also of major interest, in particular novel approaches and new results of marker assisted breeding, QTL cloning, integration of conventional and marker assisted breeding, and QTL studies in crop plants.
