Groundnut production in India • 1st most important oilseed crop in India • Area: 6.6 million ha • Production: 5.9 million t • Productivity of groundnut – 0.97 t ha-1 • ~ 20% of world production comes from India alone!
Drought Leaf spot Rust Constraints in production
- Indian Council of Agricultural Research Indian Groundnut Genomics Consortium Three main partners: ICRISAT, Patancheru, A.P.(Intern. Crops Res. Inst. Semi-Arid Tropics) NRCG, Junagadh, Gujarat(National Research Centre for Groundnut) UAS, Dharwad, Karnataka (University of Agricultural Sciences) Team of multidisciplinary scientists
Activities • Generation of microsatellite-enriched libraries and identification of ~500 microsatellite or simple sequence repeat (SSR) loci • Generation of groundnut unigene-derived SNP markers and development of cost effective CAPS assay • Construction of integrated genetic maps with SSR, SNP and DArT markers • Phenotyping of mapping populations at three locations (ICRISAT, NRCG, UASD) over 3 years • Identification of genes/QTLs associated with resistance to foliar diseases (rust and late leaf spot) and tolerance to drought (TE, SCMR and SLA)
SSR marker development • In silico approach after mining sequence data - Aeschynomenoid/ Dalbergoid and Genistoid clades of the Leguminoae (15 genera) - 6 genera Adesmia, Amorpha, Dalbergia, Chaetocalyx Lupinus and Stylosanthes: 411 seqs contained SSRs . - Primer pairs for 109 unique SSRs - 79 functional in one of six genera - 51 primer pairs functional in peanut • BAC-end sequence derived SSRs (Doug Cook)
