HPRC as a Platform for Improving Productivity of Dryland Hybrid Crops - Pearl Millet, Sorghum and Pigeonpea

  1. About ICRISAT: www.icrisat.org ICRISAT’s scientific information: http://EXPLOREit.icrisat.org June 2019 HPRC as a Platform for Improving Productivity of Dryland Hybrid Crops - Pearl Millet, Sorghum and Pigeonpea ICRISAT-HYBRID PARENTS RESEARCH CONSORTIUM (HPRC) ▪▪ Hybrids show 30-40% heterosis over the best OPVs in Pearl millet, Sorghum and Pigeon pea ▪▪ ICRISAT develops hybrid parents and cultivars for traits of interest in these three crops ▪▪ ICRISAT recognizes Private Sector (PS) seed companies as a valuable partners for research on hybrid cultivar development and commercialization ▪▪ Hybrid Parents Research Consortia was established in 2000 at ICRISAT, which is currently in Vth Phase (2019-2023) ▪▪ At present, about 30 companies from various countries are partnering in HPRC. This approach harnesses synergies between CGIAR and the PS in the development and marketing of seed of improved cultivars, without compromising the CG’s global research agenda in delivering international public goods (IPGs). ACTIVITIES UNDER HPRC TO SUPPORT SEED COMPANIES ▪▪ ICRISAT organizes Scientists Field Days biennially each for pearl millet, sorghum and pigeonpea; scientists from different organizations and based on their selection are provided seeds of different parents, breeding materials (with detailed information on pedigrees, disease reaction and other important traits) ▪▪ Provide some of the specialized services (e.g., screening of private sector lines and hybrids for resistance to crop specific diseases) ▪▪ ICRISAT holds Consortium Consultation Meeting (CCM) biennially where in the consortium seed companies, as a group, present their views on the emerging issues requiring possible research intervention by ICRISAT (priority setting). ▪▪ This provides a platform to member seed companies evaluate their promising pipe-line hybrids across different agro-ecological zones. ▪▪ Provides platform for specialized training in breeding, pathology and molecular marker technology through structured programs ▪▪ Support nucleus seed supply ▪▪ Facilitate networking. In case more information is required, please contact Dr PM Gaur, p.gaur@cgiar.org; For Pearl millet: Dr SK Gupta, s.gupta@cgiar.org, 9949003066 For Sorghum: Dr A Ashok Kumar, a.kumar@cgiar.org, 9000414124 For Pigeonpea: Dr Anupama Hingane, h.anupama@cgiar.org, 7674030007 Crop Scientists Field Day Year Number of seed companies attended Number of participants from seed companies Number of Public Sector organizations Number of participants from Public Sector Seed of breeding lines supplied Total number of samples supplied Pearl millet 2018 24 47 18 29 2400 7845 Sorghum 2019 8 14 7 24 1600 4100 Pigeonpea 2017 9 22 9 27 677 2186 Target traits/Adaptations in different crops Sorghum ▪▪ Rainy season: Dual-purpose types with shoot fly and grain mold resistance; high IVOMD ▪▪ Post rainy sorghum: Dual-purpose types with large white lustrous grains and high IVOMD; shoot fly, charcoal rot resistance and drought tolerance ▪▪ Sweet/high biomass sorghum: Higher stalk yield, juice yield and brix % in sweet sorghum and higher biomass yield, bmr trait in HBM ▪▪ Forage sorghum: High tillering, thin stalks, leaf disease resistance, ratoonability, bmr, higher IVOMD. Pearl millet ▪▪ Rainy season: Dual-purpose types, Downy mildew and Blast tolerance, high Fe and Zn ▪▪ Drought prone areas in rainy season: Dual-purpose with drought tolerance, Downy mildew and blast tolerance ▪▪ Summer season: Dual-purpose, high heat stress tolerance during flowering period, Downy mildew and blast tolerance ▪▪ Forage pearl millet: Multi-cut/Single cut, leaf disease resistance, high green/dry biomass with better forage quality (protein and IVOMD), bmr types. Pigeonpea ▪▪ Medium duration: Fusarium wilt, sterility mosaic disease and phytophthora blight resistance, water- logging tolerance, high protein content and market preferred traits like seed size and high dal recovery ▪▪ Mid-early duration: Fusarium wilt, sterility mosaic disease and phytophthora blight resistance, water- logging tolerance, high protein content and market preferred traits like seed size and high dal recovery ▪▪ Short-duration: Fusarium wilt and phytophthora blight resistance, water-logging tolerance and market preferred traits like seed size and high dal recovery.
