Article
Plant breeding can be made more efficient by having fewer, better crosses
(BioMed Central, 2013)
Background: Crop yields have to increase to provide food security for the world?s growing population. To achieve these yield increases there will have to be a significant contribution from genetic gains made by conventional ...

Farmer perceptions on maize cultivars in the marginal eastern belt of Zimbabwe and their implications for breeding
(African Crop Science Society, 2006)
Productivity of maize ( Zea mays check for this species in other resources ) is low in the small-holder sector of Zimbabwe because the crop is grown under stress-prone environments and limited resources. The objective of ...

Molecular genetic diversity and population structure of Ethiopian white lupin landraces: implications for breeding and conservation
(Public Library of Science, 2017)
White lupin is one of the four economically important species of the Lupinus genus and is an important grain legume in the Ethiopian farming system. However, there has been limited research effort to characterize the ...

Rapid breeding and varietal replacement are critical to adaptation of cropping systems in the developing world to climate change
(Elsevier, 2017)
Plant breeding is a key mechanism for adaptation of cropping systems to climate change. Much discussion of breeding for climate change focuses on genes with large effects on heat and drought tolerance, but phenology and ...

Strategies for selecting crosses using genomic prediction in two wheat breeding programs
(Crop Science Society of America, 2017)
The single most important decision in plant breeding programs is the selection of appropriate crosses. The ideal cross would provide superior predicted progeny performance and enough diversity to maintain genetic gain. The ...

Sub-Saharan African maize-based foods: technological perspectives to increase the food and nutrition security impacts of maize breeding programmes
(Elsevier, 2018)
The demand for maize in Sub-Saharan Africa will triple by 2050 due to rapid population growth, while challenges from climate change will threaten agricultural productivity. Most maize breeding programmes have focused on ...
Article
A general Bayesian estimation method of linear-bilinear models applied to plant breeding trials with genotype × environment interaction
(Springer Verlag; American Statistical Association; International Biometrics Society, 2012)
Statistical analyses of two-way tables with interaction arise in many different fields of research. This study proposes the von Mises-Fisher distribution as a prior on the set of orthogonal matrices in a linear-bilinear ...
Article
Breeding and genetic estimation of spring bread wheat populations of the Siberian shuttle breeding nursery of CIMMYT
(Institute of Cytology and Genetics of Siberian Branch of the Russian Academy of Sciences, 2012)
Shuttle breeding contributes much to the breeding to common wheatvarieties resistantto adverse environmental factors by involving new sources of valuable biological and economical features from the world?s gene pool. ...
Article
Crop breeding chips and genotyping platforms: progress, challenges, and perspectives
(Elsevier, 2017)
There is a rapidly rising trend in the development and application of molecular marker assays for gene mapping and discovery in field crops and trees. Thus far, more than 50 SNP arrays and 15 different types of ...
Article
Estimating the economic impact of breeding nonspecific resistance to leaf rust in modern bread wheat
(American Phytopathological Society (APS), 1998)
Breeding for resistance to rust diseases in wheat is an example of productivity maintenance research. Productivity maintenance research is necessary to avoid contractions in the wheat supply curve that result from changes ...
