  1. Comparative performance of winter wheat genotypes under dryland and irrigated environments R.C. Sharma1, A.I. Morgounov2, H.J. Braun2, B. Akin2, M. Keser1, D. Bedoshvili1,2, A. Bagci3, M. van Ginkel1, A. Yahyaoui1, S. Rajaram1 1ICARDA; 2CIMMYT; 3Celcuk Univ., Turkey

  2. Abbreviations • IWWIP : International Winter Wheat Improvement Program • IWWYT : International Winter Wheat Yield Trial • SA : Semi-arid • IR : Irrigated • CWANA: Central and West Asia and North Africa

  3. International Winter Wheat Program (IWWIP) Cooperative winter wheat breeding program: Ministry of Agric. and Rural Affairs, Turkey CIMMYT ICARDA

  5. Objectives • Compare grain yield of wheat genotypes targeted to irrigated and semi-arid environments in the IWWIP • Examine high yielding wheat genotypes under low and high productive environments for their specific and broad adaptation

  6. Materials and Methods • IWWYT – SA • IWWYT – IR • Comparison of grain yield levels of genotypes in IWWYT-SA and IWWYT-IR evaluated under similar management conditions • Comparison of grain yield levels of genotypes in IWWYT-SA tested under low and high productive environments

  13. Study 1: IWWYT-SA vs. IWWYT-IR • Mean grain yield (t/ha) under similar management IWWYT-SA IWWYT-IR Portugal-07 5.31 5.54 Armenia-08 3.25 3.33 Russia-08 6.16 5.47 Serbia-08 8.01 8.90 Uzbekistan-08 5.32 4.89 Uzbekistan-09 4.62 5.55

  14. Study 1: IWWYT-SA vs. IWWYT-IR • Highest grain yield (t/ha) under similar management • IWWYT-SA IWWYT-IR • Portugal-07 7.49 7.52 (0%) • Armenia-08 4.20 4.75 (+12%) • Russia-08 8.13 7.53 (-8%) • Serbia-08 9.96 10.16 (+2%) • Uzbekistan-08 6.55 6.05 (-8%) • Uzbekistan-09 6.43 6.75 (+5%)

  16. Study 2: Highest yielding genotypes in the 7th IWWYT-SA under low and high productive environments, 2005

  17. Study 2: Highest yielding genotypes in the 8th IWWYT-SA under low and high productive environments, 2006

  18. Study 2: Highest yielding genotypes in the 9th IWWYT-SA under low and high productive environments, 2007

  19. Study 2: Highest yielding genotypes in the 10th IWWYT-SA under low and high productive environments, 2008

  20. Conclusions Grain yield of highest yielding genotypes in IWWYT-IR and IWWYT-SA are comparable under irrigated management Certain genotypes developed for dryland also possess yield potential that could efficiently utilize management practices for irrigated management In general, different sets of genetic materials are needed under strictly semi-arid and irrigated environments A few lines targeted towards stressed conditions in fact possess yield plasticity resulting in their superior performance both under dryland and irrigated conditions
