CIMMYT annually distributes improved germplasm developed by its researchers and partners in international nurseries trials and experiments. The High Temperature Wheat Yield Trial (HTWYT) is a replicated yield trial that contains spring bread wheat (Triticum aestivum) germplasm adapted to Mega-environment 1 (ME1) which represents high temperature areas.

Gene-based marker data from international screening nurseries for marker-assisted selection.

The average Bangladeshi consumes more than 171kg of rice per year. Despite the is ranked 93rd among 239 countries of the world in terms of the physical size, the country is the 8th largest populace country in terms of the total population which is more than 164 million in 2017. Bangladesh has nonetheless largely achieved rice self-sufficiency. This...

The genotypes from the International Bread Wheat Screening Nursery (IBWSN) multiplication trial, which is designed to rapidly assess a large number of advanced generation (F3-F7) lines of spring bread wheat under Mega-environment 1 (ME1) that represents diversity for a wide range of latitudes, climates, day lengths, fertility conditions, water management,...

In genomic prediction deep learning artificial neural network are part of machine learning methods that incorporate parametric, non-parametric and semi-parametric statistical models. Kernel methods are seeing more flexible, and easier to interpret than neural networks. Kernel methods used in genomic predictions comprise the linear genomic best linear...

For the first time in history, the emergence of wheat-blast in Bangladesh has generated major food security concerns. The Bangladesh Agricultural Research Institute (BARI) together with the International Maize and Wheat Improvement Center (CIMMYT) developed and released the wheat variety BARI Gom 33 that is resistant to wheat blast and other common...

Early generation germplasm developed by the IWYP Hub and containing IWYP traits of interest. This germplasm is made avaiable in addtion to the available International Wheat Improvement Network (IWIN) Nurseries from CIMMYT. All germplasm requests requires a signed sMTA.

Breeding lines cultivated in CENEB (C. Obregon) during cropping cycle 17-18 were analyzed for PPO activity

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...

In this study, we evaluated genome-based prediction using 35,403 wheat lines from the Global Wheat Breeding Program of the International Maize and Wheat Improvement Center (CIMMYT). We implemented eight statistical models that included genome-wide molecular marker and pedigree information in two different validation schemes. All models included main...

This file provides supporting material for the manuscript entitled ' Estimation of Physiological Genomic Estimated Breeding Values (PGEBV) Combining full Hyperspectral and Marker Data Across Environments for Grain Yield Under Combined Heat and Drought Stress in Tropical Maize (Zea mays L.)'. The file includes spreadsheets containing information on the...

Since 2012, Australian support has resulted in the release of 23 wheat varieties by Afghanistan’s National Varietal Release Committee (NVRC). These varieties deliver both improved yield and disease tolerance. A 2015/16 farmer survey confirmed that farmers were indeed sharing seed with an average of three relatives/neighbours – although with no indication...

While there existed some empirical evidence of the incidence of zero-tillage (ZT) adoption in wheat – rice farming systems in Punjab, in 2013 no such assessment existed for Bihar, one of the major focal points of CSISA activities in the second phase. In Bihar, a relatively extensive network of ZT service providers exists, and the technology is probably...

To identify the main limiting factors to maize and bean production in Central America, field trials were established in six maize- and bean-producing regions in Guatemala, Honduras and El Salvador. Potential yield-limiting factors were evaluated in the 2017 growing season, and included: water stress, nutrient deficiency, pest and disease pressure, and/or...

Large tracts of land in the upland plateau ecology of Odisha are not suitable for rice production and are largely left fallow. In Mayurbhanj district of the plateau area, nearly half of the total cultivable area (43%) falls into the upland category that is not very suitable for growing rice. The tribal farming population either leave this land fallow or...
