Superior varieties are crucial for sustainable strawberry production in the UK. Production costs have increased far more than the price of the fruit produced, meaning new varieties must be cheaper and easier to grow to keep their production profitable. Plant architecture (the way the strawberry plant grows), including how many leaves the plant produces, how the leaves are positioned and how the fruit and flowers are displayed, is critical for profitable production. Plant architecture has important effects on how many berries are produced and how sweet those berries are. It also affects how easily plants will get diseased or infested with pests (the denser the canopy, the worse), and it affects how easily pickers can access the fruit, with very bushy plants making picking berries much slower. It has been estimated that plants with well-balanced architecture could reduce production costs by more than 10%, making production significantly more profitable and saving an estimated £20 million across the whole of the UK every year. Plant breeders have therefore tried to breed new varieties with good plant architecture, but the process is difficult because the traits are complex. This project will aim to develop molecular markers to help breed new strawberry varieties. It will use cutting edge machine-learning technologies to capture data on plant architecture and use this, along with information about the DNA of the strawberry plants to develop tools to breed strawberries with better plant architecture in a classical way (without the use of GM technology). The project outcomes will lead to the development of superior, more sustainable strawberry varieties for the UK that will keep the growers profitable.

优越的变化对于英国的可持续草莓生产至关重要。生产成本的增长远远超过了生产的水果价格，这意味着新的变化必须便宜且更容易增长，以使其生产盈利。植物建筑（草莓植物的生长方式），包括植物产生了多少叶，叶子的定位方式以及如何展示果实和花朵，对盈利生产至关重要。植物建筑对生产多少浆果以及这些浆果的甜味有重要影响。它还会影响植物会被虫子（稠密的树冠，糟糕）疏离或感染的植物如何容易地影响采摘者的果实，而挑剔的植物非常浓密，捡拾浆果的较慢得多。据估计，具有均衡建筑的工厂可以将生产成本降低超过10％，从而使生产更加有利可图，并每年在整个英国节省估计的2000万英镑。因此，植物育种者试图培养具有良好植物建筑的新品种，但是由于特征很复杂，因此很难繁殖。该项目将旨在开发分子标记，以帮助繁殖新的草莓品种。它将使用尖端的机器学习技术来捕获有关植物建筑的数据，并使用有关草莓植物DNA的信息，以开发工具，以经典的方式（不使用GM技术），以更好的植物建筑繁殖草莓。该项目的成果将导致英国优越，更可持续的草莓品种的发展，这将使种植者盈利。
