Souvenir published during 5th National Seminar on " Climate Resilient Saline Agriculture: Sustaining Livelihood Securit.The committed endeavours in agricultural research and development have helped transcending the boundaries of production and productivity despite the serious constraints of dwindling size of holdings, vagaries of weather and climatic variability marked with recurrent incidences of calamities like droughts and floods, apart from over exploitation of natural resources and poor quality irrigation water in resource poor conditions. In order to sustain the achievements made in farming sector, there is a need to develop innovative technologies and also transfer the same among farming community. The farmers in India have been the crusaders of several revolutions in agriculture. Central Soil salinity Research Institute has developed several innovative technologies in the field of salt affected soils and use of poor quality water in agriculture in the changing climatic scenario. It is planned to bring the researchers, policy planners, farmers, and developmental personnel’s on a common platform to evolve comprehensive and holistic recommendations for climate resilient saline agriculture sustaining livelihood security in resource poor natural resource conditions in the country. In view of this background, scientific community engaged in reclamation and management of salt affected soils and poor quality waters had formed Indian Society of Soil salinity and Water Quality to address the issues of stressed environment at global, national, regional and local levels. The 5th National Seminar on “Climate Resilient Saline Agriculture: Sustaining Livelihood Security” would focus on the issues related to resource poor conditions for betterment of the farming community and will benefit all concerned and contribute to Indian agriculture in changing climatic scenario for transfer the technological advancements to disseminate the information to the grass root level workers and farmers for their livelihood security. The themes in this seminar cover modern tools and techniques for diagnosis and prognosis of salt affected soils and poor quality waters, challenges in reclamation and management of salt affected soils, advancements in reclamation and management of poor quality waters, climate resilient approaches for enhancing agricultural productivity, multiple stress tolerance in biological systems, knowledge initiatives and policy dimensions and a special session on Western India.Indian Council of Agricultural ResearchNABAR

Assessing the Effect of Salt Stress on Soybean [Glycine max (L.) Merrillis] Genotypes Using AMMI and GGE Biplot Analysis

Not AvailableThe genotype × environment interaction manipulates the selection criteria in a multipurpose crop like soybean. A total 108 soybean genotypes were evaluated at normal tap water (Control), field sodicity conditions (pH 9.0 and 9.3) and saline water (ECiw 5.0 and 8.0 dS m-1) at ICAR-CSSRI, Karnal from 2017-2020. Yield and associated data were analyzed using the AMMI and GGE biplot. The AMMI analysis of variance for seed yield detected significant effects for genotype, environment and genotype × environment interaction. The environment effect was responsible for the greatest part of the variation, followed by genotype and genotype × environment interaction effects. The ‘which-won-where’ feature of the GGE biplot identified wining genotypes SL-1226 and SL-1258 in the saline (up to ECiw 8 dS m-1) and sodic (up to pH 9.3) and SL-1242 in control conditions whereas, PS-1225 across the environment was the most ideal and these genotypes could be used as donor for breeding soybean for salt tolerance. This indicates that characterization of germplasm using GGE and AMMI model is important for determining visual comparisons, adaptability/stability focusing on overall performance to identify superior genotypes.Not Availabl

Genetic dissection and identification of candidate genes for salinity tolerance using Axiom®CicerSNP array in Chickpea

Not AvailableGlobally, chickpea production is severely a ected by salinity stress. Understanding the genetic basis for salinity tolerance is important to develop salinity tolerant chickpeas. A recombinant inbred line (RIL) population developed using parental lines ICCV 10 (salt-tolerant) and DCP 92-3 (salt-sensitive) was screened under field conditions to collect information on agronomy, yield components, and stress tolerance indices. Genotyping data generated using Axiom®CicerSNP array was used to construct a linkage map comprising 1856 SNP markers spanning a distance of 1106.3 cM across eight chickpea chromosomes. Extensive analysis of the phenotyping and genotyping data identified 28 quantitative trait loci (QTLs) explaining up to 28.40% of the phenotypic variance in the population. We identified QTL clusters on CaLG03 and CaLG06, each harboring major QTLs for yield and yield component traits under salinity stress. The main-e ect QTLs identified in these two clusters were associated with key genes such as calcium-dependent protein kinases, histidine kinases, cation proton antiporter, and WRKY and MYB transcription factors, which are known to impart salinity stress tolerance in crop plants. Molecular markers/genes associated with these major QTLs, after validation, will be useful to undertake marker-assisted breeding for developing better varieties with salinity tolerance.Not Availabl

Review: Carbonate aquifers and future perspectives of karst hydrogeology in India

International audienceAbout 3 % of India's total land surface is occupied by carbonate rocks which are mostly karstified and constitute a significant source of groundwater. The groundwater drawn from these aquifers matches the water demand of -35 million people living in 106 districts of the country and also the water needs of livestock, irrigation and industry. The studies on karst in India carried out so far have mostly addressed geology, hydrology and groundwater contamination. A literature survey suggests that there is a need for detailed research, applying new approaches and techniques for proper carbonate aquifer identification, characterization and management. Such specific approaches will improve modeling, exploitation and protection of karst groundwater. An overview of the research carried out on groundwater resources of karst formations in India is presented, which also throws light on the protection of karst aquifers from existing anthropogenic activities such as mining and groundwater over-exploitation
