1 What is happening in peanut genomics in India Rajeev Varshney Senior Scientist- Applied Genomics, ICRISAT Coordinator, Indian Groundnut Genomics Consortium Leader, Comparative Genomics & Gene Discovery (Generation Challenge Programme)

2 Groundnut production in India 1 st 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!

3 Constraints in production Drought Leaf spot Rust

4 Indian Groundnut Genomics Consortium - Indian Council of Agricultural Research 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

5 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)

6 What we already have done at ICRISAT…

7 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)

8 Genetic map construction Cultivated x Cultivated TAG 24 x ICGV 86031 -RIL Mapping water use efficiency QTLs Collab. D Bertioli, Brazil G He, USA S Knapp, USA

9 Molecular diversity fastigiata: 488 hypogaea: 321 wild: 47 916 accessions at 21 SSR loci Reference collection (300 genotypes) Exploring association genetics approach

10 What we plan to do at ICRISAT (under Troplical Legume Genomics project)…

11 Generation Challenge Programme (www.generationcp.org) Launched in August 2003 10-year framework (2004–2008; 2009–2013) About US$16M annual budget –75% Research –15% Training and capacity building –10% Management cost Major donors –European Community –DFID –The Bill & Melinda Gates Foundation –World Bank –Switzerland Target areas: Marginal drought-prone environments –Africa (SSA) –South and South East Asia –Latin America Mandate crops (CGIAR) – 22 crops A CGIAR Challenge Programme hosted at CIMMYT, Mexico

12 SP4 DB, Information Network SP5 Training/Capacity SP1 Germplasm SP2 Gene Discovery SP3 MAS Improved germplasm in farmers’ fields Phenotyping GCP Research Structure Breeding programmes Improved genotypes (Delivery plans) Director: Jean-Marcel Ribaut (SPL: J-C Glaszmann)(SPL: R K Varshney)(SPL: P Monneveux) (SPL: T van Hintum) (SPL: C de Vicente)

13 Activity 1: Explore Diversity Objective 5 + Activity 2: Generate Genomic Resources Activity 3: Identify Marker Development (Biotic) Activity 4: Identify Marker Development (Abiotic) Activity 5: Improve Germplasm Development Objectives 1-4 Objective 6 Tropical Legume I project (GCP) US $ 11 m Peanut Cowpea Common bean Chickpea Comparative Genomics Training

14 Project Activities Develop germplasm for genetic studies and modern breeding –Bonny Ntare (ICRISAT, Mali) Generate genomic resources for genetic studies and modern breeding –Andy Paterson (University of Georgia, USA) Identify molecular markers and genes for biotic stress resistance –David Bertioli (Catholic University, Brazil) Identify molecular markers and genes for drought tolerance –Vincent Vadez (ICRISAT, India) Improve locally adapted germplasm for target traits through modern breeding –Emmanuel Monyo (ICRISAT, Malawi) Objective 1- Peanut (PI: Dave Hoisington)

15 Objective 5- Cross species (PI: Doug Cook) Doug Cook David Bertioli Andy Paterson
