39th Semi-Arid Wheat Screening Nursery

Ravi Singh Carolina Saint Pierre (2022, [Dataset])

The Semi-Arid Wheat Screening Nursery (SAWSN) is a single replicate trial that contains diverse spring bread wheat (Triticum aestivum) germplasm adapted to low rainfall, drought prone, semi-arid environments typically receiving less than 500 mm of water available during the cropping cycle. CIMMYT's breeding approach attempts to combine high yield potential with drought resistance for ME4. The combination of water-use efficiency and water responsive traits plus yield potential is important in drought environments where rainfall is frequently erratic across years. When rains are significantly above average in certain years, the crop must respond appropriately (water responsive) with higher yields, while expressing resistance to the wider suite of diseases that appear under more favorable conditions. Constrains including leaf, stem and yellow rusts, and Septoria spp., Fusarium spp., Pyrenophora tritici-repentis tan spot, nematodes and root rots must be considered. It is distributed to 120 locations, and contains 150-250 entries.

11th Stress Adapted Trait Yield Nurseries

Matthew Paul Reynolds Carolina Saint Pierre (2022, [Dataset])

Within the framework of SATYN, two types of nurseries are produced: SATYN series with odd numbers are lines for drought-stressed areas, and SATYN series with even numbers are lines for heat stress conditions. These nurseries have been phenotyped in the major wheat-growing mega environments through the International Wheat Improvement Network (IWIN) and the Cereal System Initiative for South Asia (CSISA) network, which included a total of 136 environments (site-year combinations) in major spring wheat-growing countries such as Bangladesh, China, Egypt, India, Iran, Mexico, Nepal, and Pakistan.

Evaluation of international Low-ODAP grasspea lines for highlands in El Batán, México (2016)

Ravi Gopal Singh (2022, [Dataset])

Several international varieties of Low-ODAP grass pea were evaluated. Some of the variables measured were Total biomass weight (g), Fresh weigth of the subsample (g), Dry weight of the subsample (g) and Harvest area (m²). The experiment was conducted in El Batán, México.

53rd International Durum Yield Nursery

Karim Ammar Carolina Saint Pierre (2022, [Dataset])

International Durum Yield Nurseries (IDYN) are replicated yield trials designed to measure the yield potential and adaptation of superior CIMMYT-bred spring durum wheat germplasm that have been developed from tests conducted under irrigation and induced stressed cropping conditions in northwest Mexico. These materials have been subjected to numerous diseases (leaf, stem and yellow rust; Septoria tritici blotch) and varied growing environments. It is distributed to 70 locations, and contains 50 entries.

2022 CIMMYT Maize Eastern Africa Product Profile 1A (PP1A) Product Announcement

Berhanu Tadesse Ertiro Yoseph Beyene Suresh L.M. Manje Gowda Anani Bruce Vijay Chaikam Walter Chivasa Mosisa Worku Regasa Michael Olsen Aparna Das Nicholas J. Davis Prasanna Boddupalli (2022, [Dataset])

New and improved maize hybrids, developed by the CIMMYT Global Maize Program, are available for uptake by public and private sector partners, especially those interested in marketing or disseminating hybrid maize seed across Eastern Africa and similar agro-ecologies in other regions. Each year, CIMMYT’s Global Maize Program conducts regional on-station and on-farm hybrid maize trials through a network of NARS and private seed companies in eastern and southern Africa under various management and environmental conditions. Promising maize hybrids developed by the CIMMYT-Africa team, along with relevant checks from private seed companies and National Agricultural Research Programs, are included in these trials. Phenotypic data collected in Stage 4 and Stage 5 trials for the selected hybrids from Product Profile 1A (PP1A) as well as information about the trial sites and management and environmental conditions are provided in this dataset.

Replication Data for: Incorporating male sterility increases hybrid maize yield in low input African farming systems

Hugo De Groote Jill Cairns Michael Olsen (2021, [Dataset])

In sub-Saharan Africa, maize is a staple crop but yields remain sub-optimal. A novel hybrid seed technology offers the opportunity to reduce seed production costs and increase yields. This dataset contains data from on-farm and on-station trials collected in 2017 to 2019 in South Africa, Kenya and Zimbabwe to assess this hybrid seed production technology. The results of the analysis are presented in the accompanying article.
