Methodologies for root drought studies in rice
Root biology is at the forefront of progressing fields to improve agricultural productivity in low-input systems. Although there is a strong case for the role of roots in plant performance under drought stress, appropriate methods for evaluating them in relation to performance under drought (particularly in rice) are less clear-cut. The research community needs a better understanding of the genetic variation in rice for drought response and root traits. The focus of this manual is the description of relatively high-throughput, low-cost, and precise root phenotyping techniques, adopted by researchers across the world, that have been developed for drought studies on rice. Field phenotyping protocols for root studies in precise drought-stress treatments, as well as a range of root phenotyping systems, are described. Protocols to associate root traits with other plant traits and productivity are also included.
