GRM 2011: Improving drought tolerance in chickpeas for Africa and Asia

  1. 1. Improving drought tolerance in chickpeafor Africa and AsiaPooran GaurProject Delivery CoordinatorICRISAT, Patancheru, Indiaon behalf of Chickpea GroupGCP Challenge Initiative
  2. 2. Target countries for chickpea CIIndiaEthiopiaKenyaTanzania
  3. 3. Various projects linked to chickpea CIG6007.04/G6010.04: Tropical Legumes I (TL I) - Objective 4: ChickpeaPhase 1&2 (2007- 2014)PI and Lead Institute: Rajeev Varshney, ICRISATG4008.12: Linking genetic diversity with phenotype for drought tolerancein reference collection (2008 - 2011)PI and Lead Institute: L Krishnamurthy, ICRISATG7009.02: Mapping and validation of QTL for drought tolerance traits(2009 -2011)PI and Lead Institute: Pooran Gaur, ICRISATG7009.06: Development of a SNP platform (Nov 2009-Oct 2011)PI and Lead Institute: Doug Cook, UC-DavisTL-I complementary project in India - funded by The Dept. ofBiotechnology, Govt. of India (2011-14)PI and Lead Institute: Rajeev Varshney, ICRISAT
  4. 4. Major Activities1. Development of genetic and genomicresources2. Identification and validation of markersassociated with QTL for drought tolerancetraits3. Marker-assisted introgression of droughttolerance traits in farmer-preferred cultivars4. Marker-assisted recurrent selection (MARS)for cumulating favorable alleles for droughttolerance
  5. 5. • 1655 novel SSR markersdeveloped and validated. Withthese the total number of SSRmarkers available for chickpeais over 2500• GoldenGate assay for 768 SNPsdeveloped• 2486 KASPar SNPs weredesigned. 1484 SNPs werefound polymorphic in a set of94 genotypes.Development of molecularmarkers for chickpeaHomozygoteHeterozygoteHomozygoteNTC
  6. 6. Development of high density linkage mapchickpea1291 loci were mapped on to eight linkage groupsThe total map distance ~845.5 cMAverage inter marker distance 0.6 cM/marker

  13. 13.  Workshop on “Modern Breeding Technologies for ChickpeaImprovement” held during Oct 25 – Nov 19, 2010 16 scientists participated12 from five countries ofAfrica (Ethiopia, Kenya,Tanzania, Malawi,Algeria)and 4 from fourcountries of Asia (India,Nepal, Bangladesh,Myanmar) Included lectures, demo, field/lab visits, comprehensive data analysis,interaction with different subject matter specialists at ICRISATCapacity building:Modern breeding workshop
  14. 14.  Kenya:- Ms Serah Songok, PhD student, Egerton University- Ms Alice Koskie, PhD student, WACCI- Mr Moses Oyier, MSc student, Egerton University Ethiopia:- Mr Musa Jarso, PhD student, Addis Ababa University- Mr Kebede Teshome, PhD student, Haramaya Uni.- Mr Getachew Tilahun, Addis Ababa UniversityCapacity Building:Degree students
  15. 15. Field trial and data management• 11 datasets compiled and curated• Trait ontology made available• Pedigree information of ICRISAT’s chickpea breedingprogram moved to ICIS• Plan to use IB Fieldbook from coming crop season• Handheld evaluated and keen to use Galaxy tab 10.1
  16. 16. Linkages with TL-II• Key partners are common• Joint capacity building onintegrated breeding ofchickpea• Products from TL-I alreadybeing integrated in TL-IIactivities
  17. 17. The Chickpea CoP was established at the TL-I annualmeeting in Madrid during May 2011.CoP Coordinator: Pooran Gaur, ICRISATCoP Mentor: Teresa Milan, Universidad de Cordoba, SpainAim: to promote knowledge sharing and mutual learningon integrated chickpea breedingCommunity of Practice (CoP) forintegrated breeding of chickpea
