Starch is a major component of cereal grains and the size and shape of starch granules have significant impact on grain use. In wheat, there are two types of granules (A and B). The smaller, B-granules have negative impacts on many end-uses of wheat.To solve this problem, we have generated a new type of wheat, BlessT that lacks B-granules. This was achieved by identifying two regions of the genome harbouring genes required for B-granule initiation and then stacking deletions of these regions together in the same plant. A Pathfinder Report assessed the market potential of BlessT and concluded that the technology targets a number of large and growing markets. It identified how the changed processing ability of BlessT could be developed commercially. In this project, these targets will be pursued by providing:1) Further data on processing properties2) Bulk volumes of grain for further testing by potential commercial partners3) Field trials that measure the effects on yield

淀粉是谷物的主要成分，淀粉颗粒的大小和形状对谷物的利用有重要影响。小麦有两种颗粒（A和B）。较小的b颗粒对小麦的许多最终用途产生负面影响。为了解决这个问题，我们生产了一种新型小麦，BlessT，不含b粒。这是通过鉴定基因组中含有b颗粒起始所需基因的两个区域，然后将这些区域的缺失叠加在同一植物中来实现的。一份探路者报告评估了bliss的市场潜力，并得出结论，该技术瞄准了许多庞大且不断增长的市场。确定了如何改变福雷斯特的加工能力进行商业开发。在这个项目中，这些目标将通过提供：1)加工性能的进一步数据；2)供潜在商业伙伴进一步测试的粮食散装量；3)测量对产量影响的田间试验来实现
