 ABSTRACT

Drought is one of the most serious production constraints for world agriculture and is projected to worsen with anticipated climate change. From past few decades many scientists have been trying to understand and dissect the mechanisms of plant tolerance to drought stress using different approaches, but success is not up to the mark. Recently trait based breeding plays a major role in unravelling the problem. Trait based extensive phenotyping is the base for marker assisted breeding. Trait based mapping population was selected along with the parental lines and were screened for root traits. Roots were phenotyped using root structure which mimics the field condition. Based on the results, best recombinant inbred lines were selected which can be considered as trait donor lines.

Keywords: Drought, Phenotyping, Root structure, Roots traits.
