15AGRITECHCAT3 - Improved crop breeding programmes through advanced Pollination Control Bag materials technology

开发新的作物品种需要在具有所需特性的亲本植物之间进行控制授粉。控制这一过程的一个好方法是使用授粉控制袋（PCB）在隔离的环境中进行。这些袋子需要允许光线穿透，控制湿度，允许空气流通，同时防止其他花粉进入袋子。虽然目前的多氯联苯通常由纸质材料制成，相对便宜，但它们是一次性的，容易撕裂，容易受到蛞蝓的侵扰，这意味着环境不再足够隔离，无法确保受控的交叉授粉。因此，需要更好的pcb材料来克服这些挑战。该项目将调查开发一种创新的授粉控制袋的技术和商业可行性，以改进用于三种重要农作物（甜菜、小麦和芒草）的作物育种方案。将与学术和商业育种者一起研究和试验一系列材料（编织和非织造）、纤维技术和技术，目的是开发下一代授粉控制袋，以改善育种成果，减少因袋内温度和湿度控制不当造成的损失，并提高种子产量。

Developing new crop varieties requires controlled pollination between parent plants with the desired characteristics. A good way of controlling this process is to carry it out within an isolated environment using a pollination control bag (PCB). These bags need to allow light penetration, control humidity and allow air circulation whilst preventing other pollen from entering the bag. Although, current PCBs conventionally made from a paper-based material are relatively cheap, they are single use and have a tendency to rip easily and are prone to slug infestation, which means that the environment is no longer sufficiently isolated to ensure a controlled cross pollination. Superior materials for PCBs that overcome these challengesare therefore required. The project will investigate the technical and commercial feasibility of developing an innovative pollination control bag to improve crop breeding programmes used for three important agricultural crops: sugar beet, wheat and Miscanthus. A range of materials (woven and nonwoven), fibre technologies and techniques will be investigated and trialled with academic and commercial breeders with the aim of developing the next generation of pollination control bags to improve breeding outcomes, reduce losses caused by poor temperature and humidity control within the bag, and increase seed yield.
