A review of phenotypic evaluation of rice root screening

Abstract

Rice is considered one of the most important cereal crops for human nutrition. Meeting future demands of food security will require enhanced rice production that is more environmentally sustainable. To achieve this it is important to know the genetic and molecular mechanism controlling the root traits. High throughput phenotyping which can keep pace with genotyping is needed, but for many researchers this needs to be cheap as well as meaningful. The main focuses of this review is comparative evaluation of screening rice root system based on the phenotyping approaches. Moreover, we will review the shortcomings and benefits of current phenotyping methods, as well as the future study to overcome these shortcomings.
