Each year, CIMMYT’s Global Maize Program conducts regional hybrid maize trials through a network of NARS and private seed companies in Asia under various management and environmental conditions (site summary attached in Appendix 4). These entries are compared evaluated against the performance of relevant checks from private seed companies and National Agricultural Research Programs. The objectives of these regional trials are: 1. To identify improved maize hybrids with higher yield and agronomic performance suitable for target product profiles; 2. To help partners identify improved maize hybrids that can potentially replace outdated, less productive, less resilient and/or less profitable commercial varieties in the market; 3. To monitor the breeding progress and enhance regional genetic gains in maize breeding and product development; and 4. To enrich and widen the genetic base of improved maize germplasm through germplasm exchange. Details of Regional Trials conducted by CIMMYT in Asia in 2017 and 2018, are based on the below Target Product Profiles. 1. Product profile 1 (Tropical Rainfed (with erratic/excess rainfall) (Appendix 2): Basic traits: Intermediate maturing, yellow, high yielding, tolerant to drought and waterlogging and resistant to TLB Nice-to-have / emerging traits: FSR, BLSB, FAW CRT-3-8 – Intermediate maturing elite pre-commercial hybrids regional trial (including external and internal checks). 2. Product profile 2 (Tropical Rainfed Dry)(Appendix 3): Basic traits: Intermediate maturing, yellow, high yielding, tolerant to drought and heat and resistance to FSR Nice-to-have / emerging traits: FAW, Charcoal Rot CRT-1&2 - Intermediate maturing elite pre-commercial hybrids regional trial (including external and internal checks).

We studied a RIL population of 276 entries derived from a cross between SYN-D × Weebill 1. SYN-D (Croc 1/Aegilops Squarrosa (224)//Opata) is a synthetic derived hexaploid wheat with dark green broad leaves without wax. The RILs did not segregate for Rht-B1, Rht-D1, Ppd-A1, Ppd-D1, Vrn-A1, Vrn-A1, Vrn-D1, and Eps-D1 genes and showed a narrow range of phenology, which avoids the confounding effect of phenology to identify QTL that may otherwise be masked by crop development. The RILs population was phenotyped in a randomized lattice design with two replications under four environments -drought (2009-2010, D10), heat (2009-2010, H10), heat + drought (2011-2012 and 2012-2013, HD12 and HD13)- at the Campo Experimental Norman E. Borlaug (CENEB), CIMMYT’s experimental station at Ciudad Obregón, Sonora, Northwest Mexico (27.20°N, 109.54°W, 38 masl). Drought stress (D) was applied by normal planting (late November) with significantly reduced irrigation (total water supply 700 mm) to avoid the effect of drought; the combined stress (H+D) was applied by delayed planting date (late February) with reduced irrigation (total water supply < 200 mm).
