英文摘要
Modern agriculture needs crop varieties with improved performance for the consumer (e.g. flavour, shape, texture etc) and the producer (e.g. high yield, resistance to pests), and reduced environmental impact (e.g. lower fertiliser or pesticide input). These developments are all possible using conventional breeding backed by modern biotechnology, without the need for genetically modified (GM) plants. These improved properties are found in 'genebanks', which are collections of thousands of plant samples taken from the wild or old crop varieties, together with the many cultivars resulting from decades of selective breeding around the World. The problem with harnessing this potentially useful biodiversity in future breeding programmes is working out which samples to use. The solution is to 'genetically fingerprint' every sample and take accurate measurements of all the useful properties mentioned above. These experiments can tell us in principle which plants are likely to carry potentially useful genes. However, this huge quantity of potentially useful information remains difficult to use (hundreds of measurements in thousands of samples means millions of data points), because improvements in computer databases to store, analyse and display the results have lagged behind our ability to do the lab experiments. This project proposes to bridge that gap by developing a powerful, versatile and accessible computer database and associated computational tools, which can be applied to data collected from crop plant genebanks, to identify promising plant samples for further experimental analysis. All of these computational resources will be freely available to the World's genetic resources community.
