Abstract:
Drought is the major concern of Indian agriculture under changing scenario of climate to sustain the productivity and to fulfill the food requirement of ever increasing population. Hence, the present study was carried out at Research cum Instructional Farm and Department of Plant Physiology, Agricultural Biochemistry, Medicinal and Aromatic Plants, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during Kharif during 2018-19 and 2019-20. The planting materials for experiment consisted of 30 rice genotypes from IIRR, Hyderabad under AICRP on rice programme and 01 local check (Poornima) from IGKV, Raipur (C.G.). The root Phenotyping study was done in mini-rhizotron and scanning was carried out by using root scanner machine Epson Perfection V700/V750, 3.81 Version, Win Rhizo Reg 2009. The image base root Phenotyping of different rice genotypes using in mini-rhizotron the local check Poornima was registered relatively better in traits like root length, fresh and dry root weight, root diameter, root surface area, root volume followed by RFU 329, RFU 327, RFU 304 due to root parameters determines the hydraulic conductance of root that can potentially increase water uptake and contribute to improved water use efficiency in rice under water limited conditions. Thus, these genotypes may further used under farmers’ field in large scale to sustain the productivity under rainfed ecosystem of India.
