Overview of AIP contribution to wheat improvement in Pakistan: 2013-14 to 2015-16 By Krishna Joshi. 2016. Themes 1. Increasing wheat production though rapid diffusion of high yielding rust resistant wheat 2. Effective fungicides introduced, evaluated and registered for controlling wheat rusts 3. Generating a durum wheat value chain for Pakistan 4. Products based wheat breeding to ensure end use quality Institutional Innovation 20 16 s r 15 e 14 n 13 t r a p 10 f 10 o r e b m 5 5 u N 0 0 2013-14 2014-15 2015-16 Private Public  21 village-based seed groups also added to this platform Scope of the partnership  Public-private partnership  Small seed companies in rural areas  Rural Support Programmes (AKRSP, BRSP, NRSP): contact with a large grassroots organizations, smallholders & women  Partnership with NRSP-quick impacts  Private sector & RSPs vital: for routine & emergency response, e.g.UG99, wheat blast already confirmed in Bangladesh  Basis for sustainability post AIP Process adopted for implementation Moderately & highly Identified districts food insecure with food insecurity Phase 2 or 3 Selected remote parts of identified districts Smallholders (<5 acre), women headed households, tenants, vulnerable people including families affected by floods in Punjab Increasing wheat production though rapid diffusion of high yielding rust resistant wheat Activity Purpose PVS Validation for local adaptation & farmers’ preferences IRD Creating knowledge & demand for new varieties, F-F-seed flow: varietal replacement Diamond trial Replacing old improved by new improved Seed system Fast delivery of genetic strengthening gains to farmers 21.5%  Rapid transfer of genetic gains to farmers 78.5% Female Male ♀ 3739 6 0 0 26 = 3771 ♂ 12175 610 55 229 671 = 13740 Paired Seed Variety & plot PVS Diamond production & agronomic trials trial Demos provisioning trials Coverage of AIP wheat activities 22: varieties 485: t seeds 17, 511: farmers 52-63 districts Number of collaborating farmers in various wheat improvement activities 9 8003 8 s r 7 e m r s 6 a d 5178 f n a 5 g s n u ti o 4 a h p T i 3 2723 c i t r 2 a P 1046 1 321 0 0 2013-14 2014-15 2015-16 Female Male  This should form the basis for sampling frame for any impact assessment for wheat in AIP Key findings PVS  Not all new varieties were superior to check varieties; hard to beat Faisalabad08, Seher06, TD1,Pirsabak05, Zardana.  Identified superior & acceptable & not at all acceptable varieties: in a single season  Yield gain: few 100 kg to >1 ton /ha  Yield differences: statistically significant except for in Sindh
