Root Phenotyping for Field Management of crops- dryland crops V. Maruthi Principal Scientist (Agronomy) Central Research Institute for Dryland Agriculture Hyderabad

Genotype X E X M Plant Phenotyping- Agronomic Perspective Gene based approach : eg., QTLs Breeding strategies New Climate Resilient Cultivars Crop Management

Above ground plant phenotyping Below ground plant phenotyping (Root Phenotyping) Root Morphology: Root Architecture: Spatial and Temporal configuration of Root system Root Topology Plant Phenotyping

Root Phenotyping- Agronomic Perspective Factors Genotype Plant population Tillage Soil depth Drought & Excess Abiotic stress management Measure Special operations Fertilisers Drought management measures

Root Phenotyping Drought management measure: Conservation furrow Recommended Practice : One conservation furrow for every three rows of crop plants Field Expt- Greengram- ML267 vs WGG37

ML267 –No CF ML267 – CF Stage 1 (42 DAS)

Stage 2 (63 DAS) WGG37 –No CF WGG37 – CF
