Research focus

Most temperate crops including wheat and barley are annual plants, however, most perennial plant communities including the wild relatives of cereal crops have greater biomass capacity and maintain better soil and water quality. We will exploit existing genetic resources in barley including wild barley relatives to dissect the genetic control of primary and axillary meristem development. Variation in the timing of development and tiller formation will be correlated with agronomic performance in the field. Understanding the genetic basis of annual versus perennial growth will allow a targeted transfer of genes conferring perennial growth characteristics to crops with good agronomic performance.
