Research Program Genetic Gains (RPGG) Review Meeting 2021: Update on Tropical Legumes Projects (2007- 2020) By Dr Rajeev K Varshney

  1. Tropical Legumes Projects (2007- 2020) Principal Investigators: Rajeev Varshney (2013- 2020) CLL Gowda (2007- 2013) Project Coordinators: Chris Ojiewo (2017- 2020) Emmanuel Monyo (2012- 2016) Tsedeke Abate (2007- 2012)
  2. Project duration and budget Implemented in III Phases 2007-2011 $ 20.6 M 2012-2014 $21.4 M 2015-2020 $24.6 With total investment of US Implemented by three CGIAR Centers together with National Agricultural Research Systems Partners ICRISAT salary support in TLIII Region Staff budget (M) ESA region 11 2.617 WCA region 5 0.559 Asia region 17 0.894 4.070 per annum
  3. Project scope  Development and release of farmer-preferred varieties in the target crop x geography  Strengthening of the legume breeding capacity of the partner CGIAR and NARS partners  Program Improvement Plan (PIP) based on the results of the Breeding Program Assessment Tool (BPAT)  The establishment of sustainable seed delivery systems that service the needs of small-holders
  4. Project scale
  5. 101 varieties 28 varieties 111 varieties 31 varieties GROUNDNUT CHICKPEA COMMON BEAN COWPEA Earliness; P-Use efficiency Resistance to fungal diseases (Ascochyta blight, fusarium wilt) Drought Heat tolerance (Temperatures above 30 during day ; 20C at night result in yield losses) Bruchids, Pod borers, Aphids Market preferences Pest/diseases Fast cooking Palatability Quality: high oleic, oil content Fodder (haulm) quality Early and late leaf spot disease Climate resilience Resistance to parasitic weeds (striga, alectra) 23 varieties 10 varieties PIGEON PEA SOY BEAN 1. Develop & release farmer-preferred improved legume varieties traits Tropical Legumes project worked on
  6. Learn & apply new breeding tools/ approaches for greater Genetic Gain Thanks to marker-assisted breeding Tools (MAS, MARS, MABC, MAGIC populations) Rapid Generation Turnover Agree on ‘’must-have’’ & ‘’nice-to-have’’ traits across agroecologies Weigh in demand & feasibility for resistance to biotic/abiotic stresses, nutrition, market preferences,… Know what to breed for to improve genetic gains and adoption Efficient data management The missing seed market: Integrate women seed preferences in product profiling Identify key areas and develop improvement plans for CGIAR & NARS crop improvement programs More lines to screen per $ Higher selection intensity Reduced length of breeding cycle L ΔG=ihσA/L i: selection intensity; L length breeding cycle; h: heritability 2. Strengthen legume breeding capacity for faster, cost-effective delivery of well-targeted products
  7. Next Generation scientists trained 52 10 42
  8. 154 Multi stakeholder platforms eg PABRA From lab to field, seed players agree on seed roadmap to accelerate seed delivery to smallholder farmers Address adoption & scaling barriers Support diverse farmer-centered seed systems Create seed demand, raise variety awareness 1,872 seed producers engaged 168 private seed companies, 125 public seed companies, 3732 individual seed entrepreneurs, 2578 farmer organizations; 38 NGOs Stakeholder engagement along seed value chain Affordable seed certification to stimulate SME seed business & more variety releases Quality Declared Seed (QDS) in Tanzania; Truthfully labelled seeds (TLS) in India Bundle of other services to make seed different to grain and add value eg seed coating, crop insurance; Tanzania: Apron star coating increase bean yield +20-50% Test innovative seed marketing for greater access & stimulate demand like small seed packs Field days/ seedfairs Demo sites TV/radio programmes about new varieties 1,749 10,549 869 Ensure seed systems are gender-sensitive so that women benefit from legume improved seeds & new market opportunities TL III promoted innovative ways to address gender inequality in legume value chains (e.g. access to improved seeds, support women seed entrepreneurs…) In Ethiopia, ACOS seed company offer childcare for their women workers. Improve well-being and productivity of chickpea and bean value chains. 1,553 fPVS Build sustainable & inclusive seed systems
  9. Key Achievements 304 Improved varieties 4.4 M ha Area planted 397,050t Certified seeds 4.9 M t Grain Produced 22 M farmers reached U$2.6 B Value of grain
  10. IMPACT ASSESSMENT : Productivity Growth with Adoption of Chickpea Varieties Promoted in Ethiopia under TLII & TLIII (2007- 2017) 0.0 0.5 1.0 1.5 2.0 2.5 0 50 100 150 200 250 300 350 400 450 500 1999/00 2000/01 2001/02 2003/04 2004/05 2005/06 2006/07 2007/08 2008/09 2009/10 2010/11 2011/12 2012/13 2013/14 2014/15 2015/16 2016/17 Yield (t/ha) Area (ha) Production (t) Source: CSA (2007-2017) Chickpeaareaandproduction(‘000) Chickpeaproductivity(t/ha) TLII/TLIII Intervention Period
  11. Nigeria study on 1,476 farmers in Bauchi, Jigawa, Katsina, Kano and Kebbi states revealed:  An overall adoption rate of 44% (60% for female an 42% for male)  For farmers exposed to improved varieties the adoption rate was 57% (71% for female and 56% for male)  Significant yield increase of 222.44 kg/ha (391 kg/ha for female and 200.5 kg/ha for male)  Significant income increase of $135/ha ($168/ha for female and $93/ha for male) Groundnut Improved Varieties Adoption and Impact in Nigeria
  12. Tropical Legumes data ‘cubification’ Key highlights in 2020 • PowerBI allows us to display many types of data in complementary ways including maps, charts, and tables • Displays are linked so that applying a single filter updates the entire dashboard
  13. We have successfully matched the groundnut fingerprinting data with more than 700 households from the Tanzanian socioeconomic survey data. All fingerprinting information is now available in the Cube and can be explored alongside the other measures for these households. Matched: DNA fingerprinting and survey data Key highlights in 2020
  14.  35+ Bulletins  120+ Articles  6+ Books/Extension guides  4 Book chapters  24+ Conf./Proceedings/ Abstracts etc. Full info available on Hub
