High-resolution climate model projections for a range of emission scenarios are needed for designing regional and local adaptation strategies and planning in the context of climate change. To this end, the future climate simulations of global circulation models (GCMs) are the main sources of critical information. However, these simulations are not only...

The Green Revolution has led to intensive, irrigated rice-wheat systems in the Indian subcontinent that has helped the nations reduce poverty and food insecurity. The limited turn-around time between rice harvest and sowing of the winter crop (wheat) and mechanized harvesting of rice pose a critical challenge for farmers to sustainably handle the surplus...

In this data base, representative georeferenced farmer survey data from Zambia from 2011 are combined with climate data to estimate storage losses, analyze their relationship with climate, and estimate the effect of climate change on storage losses. The storage loss data include importance of different pests (maize weevils and larger grain borer), and...

Development of a methodology for mechanical maize meter evaluation that compares diverse meters in terms of seed singulation, seed damage, and spatial distribution

In plant breeding research, several statistical machine learning methods have been developed and studied for assessing the genomic prediction (GP) accuracy of unobserved phenotypes. To increase the GP accuracy of unobserved phenotypes while simultaneously accounting for the complexity of genotype × environment interaction (GE), deep learning (DL) neural...

It is a released variety in Nigeria. TDa0200012 is a male flowering and anthracnose tolerant water yam (Dioscorea alata) parental clone. TDr9902789 is male flowering white Guinea...

“Benjamin” (CIP105085.2) is a modern variety first launched in Peru in 2010. It is tracing back to a cross of SR02.177 (CIP-102025.3) x INIA-100 (CIP-102033.5). Storage root flesh color is deep orange and taste type is moist and sweet. This variety is widely adapted within temperate dry lands of the tropics and subtropics and suitable for early harvest...

“Nyota” (CIP398190.200) was released in Kenya in 2017 as a table variety. This tetraploid potato variety developed by CIP late blight resistance breeding pipeline in Peru is resistant to late blight, tolerant to warm temperatures, and has medium maturity (90-120 days). Tubers are oblong, flesh color is cream, skin color is white cream and eyes are shallow...

3 wild banana diploid varieties (ITC0249 Calcutta 4, ITC0253 Borneo, ITC0766 Paliama) 1 edible diploid banana variety (ITC0809 Maleb) 3 improved diploid banana parents (SH 3142, SH 3217, TMB2x9128-3) 1 plantain variety

IT99K-573-1-1 is a cowpea variety developed at the International Institute of Tropical Agriculture and evaluated and released as variety in several countries including Nigeria (2011), Tanzania (2012), Sierra Leone (2015) and Ghana (2017). It derived from the cross lT93K-596-9-12 X IT86D-880. It is an early maturing, photo-insensitive variety with an erect...

These two varieties are promising lines for future breeding of common beans for Africa. KATB1 is a yellow medium size commercial type highly demanded in east Africa with bush growth habit. It’s a released variety in Ethiopia, Kenya, the Democratic Republic of Congo (DRC), Tanzania and Burundi. This line is early maturing (60-65 days) and drought tolerant...

SM2775-4 (CIAT) progenitor for high and stable dry matter and erect plant type CG1141-1 (CIAT) progenitor for good cooking quality CM9912-167 (CIAT) progenitor for high and stable dry matter and erect plant type SM1127-8 (CIAT) progenitor for good cooking quality

The International Maize and Wheat Improvement Centre (CIMMYT), in collaboration with the Kenya Agriculture and Livestock Research Organization (KALRO) (previously the Kenya Agricultural Research Institute or KARI), conducted four nationally representative household surveys in the major maize growing areas during the last 30 years. All surveys used the...

Applying the difference-in-difference (DID) estimation procedure, this study quantifies the wheat blast (Magnaporthe oryzae pathotype Triticum) induced losses in wheat yield, quantity of wheat sold, consumed, or stored, as well as wheat grain value in Bangladesh in 2016 following a disease outbreak that affected over 15,000 hectares. Estimates show that...

This research examines maize SMEs in Mexico that participated in MasAgro, and their capacity to produce new maize hybrids and commercialize these hybrids in a competitive seed market. For this research, 22 companies located in different regions of Mexico were interviewed. The sample included different sizes of companies to obtain a greater variation in...

In the eastern Indian state of Bihar, most wheat farmers access seeds from the private dealers. In spite of the high seed replacement rate (>85%), the farmers still use the age-old varieties (mean age >20 years). Since most farmers consider seed dealers as a valuable source of information, a study was designed to examine the willingness of private...

e-Agrology is a system that leverages data generated in the agricultural production cycle to optimize resources and improve the decision-making process in the field. Furthermore, linking e-agrology terms with tools such as OLS, AGROVOC and RHoMIS would help increase the reach of this tool....

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

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 Southern Africa and similar agro-ecological zones. Following a rigorous trialing and a stage-gate advancement process culminating in...
