In 2007, with the help of DBT, a research project to create mutant resources for functional genomics in rice was launched through a national initiative involving ICAR-National Research Centre on Plant Biotechnology, New Delhi; ICAR-Indian Agricultural Research Institute, New Delhi; Tamil Nadu Agricultural University, Coimbatore; ICAR-Indian Institute of Rice Research, Hyderabad; University of Agricultural Sciences, Bangalore and Punjab Agricultural University, Ludhiana. Genetically well-defined material is a prerequisite for functional genomics. Thus, the project aimed to generate EMS mutants in the background of an upland and short duration aus genotype, Nagina22, characterize the mutants and use them in crop improvement. As of now, nearly 85,000 rice M2 mutant populations have been created under the project. Based on field phenotyping, gain and or loss of function mutants for tolerance to herbicide spray, drought, salinity and resistance to rice leaf and panicle blast, sheath blight and high phosphorus (P) use efficiency under low P field have been identified. Notably, the herbicide-tolerant mutant identified is under the process of registration for distribution to public and private rice breeders under appropriate material transfer agreement. Besides this, the project also aims to serve as a 'National Repository of rice EMS mutant resource' for the researchers involved in rice biology and improvement in the country.Keywords

A laboratory scale model of composite radial filter was designed, fabricated and tested for recharging aquifer with canal water. Charcoal (C), coarse sand (CS) and gravel (G) filter materials were placed in annular rings of developed radial filter in different combination of thickness, viz. 1 : 1 : 1, 1 : 1 : 2, 1 : 2 : 2 and 1 : 2 : 1 for four treatments T1, T2, T3 and T4 respectively. Flow equation for discharge through composite radial filter was developed and verified through experiments. The design depth of the filter for given discharge was also obtained. Sodium hypochlorite solution was injected through chlorination unit at the outlet of the radial filter to remove the bacteriological contamination of filtered water. The performance of composite radial filter was evaluated by analyzing canal water before and after filtration. Water quality parameters of filtered water were found to be within permissible limit at low flow rate (0.3 lps). The water quality parameters of filtered water from treatment T3 with thickness of 10, 20 and 20 cm for C, CS and G respectively was found to be comparatively better than other three treatments (T1, T2 and T4). The composite radial filter consists of C, CS and G filter media having thickness in ratio of 1 : 2 : 2 was found to be the best for recharging groundwater aquifer with canal water.Keywords
