The impact of sample selection strategies on genetic diversity and representativeness in germplasm bank collections
(BioMed Central, 2019)
Background: Germplasm banks maintain collections representing the most comprehensive catalogue of native genetic diversity available for crop improvement. Users of germplasm banks are interested in a fixed number of samples ...

Effects of drought and low nitrogen stress on provitamin A carotenoid content of biofortified maize hybrids
(Crop Science Society of America (CSSA), 2019)
Article
Should fertilizer recommendations be adapted to parkland agroforestry systems? Case studies from Ethiopia and Rwanda
(Springer Verlag, 2019)
Aims This study aimed to disentangle tree-crop fertilizer interactions in agroforestry systems, which has been suggested as an entry point for sustainable intensification of smallholder farming systems in sub-Saharan Africa ...

Optimum and decorrelated constrained multistage linear phenotypic selection indices theory
(Crop Science Society of America (CSSA), 2019)
Some authors have evaluated the unconstrained optimum and decorrelated multistage linear phenotypic selection indices (OMLPSI and DMLPSI, respectively) theory. We extended this index theory to the constrained multistage ...

Efficiency of a constrained linear genomic selection index to predict the net genetic merit in plants
(Genetics Society of America, 2019)
The constrained linear genomic selection index (CLGSI) is a linear combination of genomic estimated breeding values useful for predicting the net genetic merit, which in turn is a linear combination of true unobservable ...

Multi-trait, multi-environment genomic prediction of durum wheat with genomic best linear unbiased predictor and deep learning methods
(Frontiers, 2019)
Although durum wheat (Triticum turgidum var. durum Desf.) is a minor cereal crop representing just 5-7% of the world's total wheat crop, it is a staple food in Mediterranean countries, where it is used to produce pasta, ...

Progress in breeding for resistance to Ug99 and other races of the stem rust fungus in CIMMYT wheat germplasm
(Higher Education Press, 2019)
Races belonging to the Ug99 (TTKSK) lineage of the wheat stem rust fungus, carrying complex virulence combinations, and their migration to countries in Africa, Middle East and Asia continue to pose a significant threat to ...

Heterogeneous seed access and information exposure: implications for the adoption of drought-tolerant maize varieties in Uganda
(Springer, 2019)
Frequent droughts in sub-Saharan Africa imply water stress for rainfed agriculture and, ultimately, food insecurity, underlining the region’s vulnerability to climate change. Yet, in the maize-growing areas, farmers have ...
Article
Productivity and production risk effects of adopting drought-tolerant maize varieties in Zambia
(Emerald Publishing Limited, 2019)
Productivity and production risks affect the use of agricultural production practices and inputs, particularly in developing countries. This paper aims to investigate the effects of adopting drought-tolerant maize varieties ...

Spectral reflectance indices as proxies for yield potential and heat stress tolerance in spring wheat: heritability estimates and marker-trait associations
(Higher Education Press, 2019)
The application of spectral reflectance indices (SRIs) as proxies to screen for yield potential (YP) and heat stress (HS) is emerging in crop breeding programs. Thus, a comparison of SRIs and their associations with grain ...
