  • 1. Root Phenotyping for Field Management of crops- dryland crops V. Maruthi Principal Scientist (Agronomy) Central Research Institute for Dryland Agriculture Hyderabad
  • 2. Genotype X E X M Plant Phenotyping- Agronomic Perspective Gene based approach : eg., QTLs Breeding strategies New Climate Resilient Cultivars Crop Management
  • 3. 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
  • 4.Root Phenotyping- Agronomic Perspective Factors Genotype Plant population Tillage Soil depth Drought & Excess Abiotic stress management Measure Special operations Fertilisers Drought management measures
  • 5.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
  • 6.ML267 –No CF ML267 – CF Stage 1 (42 DAS)
  • 7.Stage 2 (63 DAS) WGG37 –No CF WGG37 – CF
  • 8.Figure . Rooting depth (cm) and root length (cm) at respective soil depths of adjacent and middle rows of mungbean of Conservation Furrow treatment (2011)
  • 9.Root Phenotyping- Agronomic Perspective Drought management measure: Conservation furrow Recommended Practice : One conservation furrow for every three rows of crop plants Refined practice: One CF for every two rows of crop plants (Greengram – 30 X 15cm)
