Increase in sustainable agricultural production in Mozambique through drought tolerant maize and conservation agriculture

Christian Thierfelder (2016, [Dataset])

The objective of this work set is to demonstrate the best options currently available for the management of conservation agriculture (CA) practices in different communities in Mozambique. Eleven communities were selected from the districts of Sofala, Tete and Manica (approximately 100 to 200 families in each community) to host these demonstration sites and six demo fields were installed in each community from 2006-2015 (9 seasons). The treatments in each community were as follows: 1. Farmers' practice (control)- Traditional management with removal of stubble. 2. Conservation agriculture- The stubble is kept in the ground, there is no preparation of the ground, and the sowing is done manually in covachos previamento open (see the management of the covachos) and with SULCADOR in Nhamatiquite. 3. Direct sowing (SD): The stubble is kept in the soil, the direct sowing is done with Matraca or sharp bread.

6th Wheat Yield Collaboration Yield Trial

Matthew Paul Reynolds Thomas Payne (2020, [Dataset])

The WYCYT international nurseries are the result of research conducted to raise the yield potential of spring wheat through the strategic crossing of physiological traits related to source and sink potential in wheat. These trials 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.

Molecular characterization of modern durum wheat Mediterranean landraces and modern cultivars with molecular markers associated to vernalization response (Vrn-1) and photoperiod sensitivity (Ppd-1) genes

Susanne Dreisigacker Karim Ammar (2020, [Dataset])

We characterized a panel of 151 durum wheat Mediterranean landraces and 20 modern cultivars via a series of molecular markers associated with Vrn-1 and Ppd-1 genes. The molecular data were used estimate the effects of the observed alleles on the time needed to reach six different growth stages under field conditions. Field experiments were carried out over six years in Lleida, northeastern Spain.

47th International Bread Wheat Screening Nursery MAS data

Susanne Dreisigacker (2017, [Dataset])

The International Bread Wheat Screening Nursery (IBWSN) is designed to rapidly assess a large number of advanced generation (F3-F7) lines of spring bread wheat under Mega-environment 1 (ME1) which represents diversity for a wide range of latitudes, climates, daylengths, fertility conditions, water management, and (most importantly) disease conditions. The distribution of these nurseries is deliberately biased toward the major spring wheat regions of the world where the diseases of wheat are of high incidence. It is distributed to 180 locations and contains 300-450 entries.

IWIN-DAP: An Excel macro to analyze CIMMYT International Wheat Trial data

Thomas Payne (2016, [Dataset])

This tutorial explains how to use the IWIN-DAP, which is an Add-In to Microsoft Excel 2010, to analyze data from CIMMYT’s International Wheat Information System. IWIN-DAP is an illustration of an alternative, quick and easy approach allowing the use of Excel to analyze multi-location trials from CIMMYT international nurseries. This tutorial explains, step by step, how to install the Add-in, download the data from CIMMYT website, and run a variety of analyses. The macro operates at the single-trait level.

43rd International Durum Screening Nursery

Karim Ammar Thomas Payne (2017, [Dataset])

International Durum Screening Nursery (IDSN) distributes diverse CIMMYT-bred spring durum wheat germplasm adapted to irrigated and variable moisture stressed environments. Disease resistance and high industrial pasta quality are essential traits possessed in this germplasm. It is distributed to 100 locations, and contains 150 entries.

Replication Data for: Genomic Prediction with Genotype by Environment Interaction Analysis for Kernel Zinc Concentration in Tropical Maize Germplasm

Edna Mageto Jose Crossa Paulino Pérez-Rodríguez Thanda Dhliwayo natalia palacios rojas XUECAI ZHANG (2020, [Dataset])

The Zinc association mapping (ZAM) panel is a set of 923 elite inbred lines from the International Maize and Wheat Improvement Center (CIMMYT) biofortification breeding program. The panel represented wide genetic diversity for kernel Zn and is comprised of several lines with tolerance/resistance to an array of abiotic and biotic stresses commonly affecting maize production in the tropics, improved nitrogen use efficiency, and grain nutritional quality. The ZAM panel_923_LINES_GENO and Zinc association mapping (ZAM) panel_phenotypic data are two files with GBS and phenotypic data for zinc (Zn) from this population. From the ZAM panel, four inbred lines (two with high-Zn and two with low-Zn) were selected and used to form the bi-parental populations, namely DH population1 and DH population2. Genotypic and phenotypic data corresponding to these populations are DH populations1&2_255_LINES_GENO and DH population1_phenotypic data and DH population2_phenotypic data

Replication Data for: Genomic prediction of kernel zinc content in multiple maize populations using genotyping-by-sequencing and repeat amplification sequencing markers

Thanda Dhliwayo Edna Mageto Michael Olsen Jose Crossa Prasanna Boddupalli XUECAI ZHANG (2020, [Dataset])

An association-mapping panel (DTMA) and two DH populations (DH1 and DH2) were used in the current study, which in total includes 487 materials. The dataset includes three types of files. One is the genotype of 487 lines sequenced by GbS, named DTMA_DH2_DH3-955690.hmp.txt; one is the genotype of 487 lines sequenced by rAmpSeq named genotype-rAmpSeq.csv; and the third type of files are the phenotypic data files named DH1-phenotype.csv, DH2-phenotype.csv and DTMA-phenotype.csv.

21st Semi-Arid Wheat Screening Nursery

Ravi Singh Thomas Payne (2019, [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.
