Conservation agriculture in southern Africa: advances in knowledge
(Cambridge University Press, 2015)
The increasing demand for food from limited available land, in light of declining soil fertility and future threats of climate variability and change have increased the need for more sustainable crop management systems. ...
Introgression of the crtRB1 gene into quality protein maize inbred lines using molecular markers
(Springer; Springer Nature, 2015)
Quality protein maize (QPM; Zea mays L.) has effectively enhanced levels of the amino acids, lysine, and tryptophan, over normal maize and provided balanced dietary protein for the health and development of monogastric ...
Large-Scale Evaluation of Maize Germplasm for Low-Phosphorus Tolerance
(Public Library of Science, 2015)
Low-phosphorus (LP) stress is a global problem for maize production and has been exacerbated by breeding activities that have reduced the genetic diversity of maize. Although LP tolerance in maize has been previously ...
Metal silo grain storage technology and household food security in Kenya
(Academic Journals, 2015)
A treatment effect and ordered logit models were used to evaluate the impact of metal silo storage technology on household food security and factors influencing adoption of metal silo. Farmers’ perception of the effectiveness ...
Nucleotide diversity and molecular evolution of the PSY1 gene in Zea mays compared to some other grass species
Phytoene synthase (PSY), which is encoded by the phytoene synthase 1 (PSY1) gene, is the first rate-limiting enzyme in the plant carotenoid biosynthetic pathway. In order to examine the genetic diversity and evolution ...
Evaluation of single cross yellow maize hybrids for agronomic and carotenoid traits
(Friends Science Publishers, 2017)
Provitamin A bioforitification of maize endosperm was found to be most convenient solution to the resolve its deficiency in the masses. Continuous efforts for persistent evaluation of diverse genetic material are prerequisite ...
Optimal design of preliminary yield trials with genome-wide markers
Previous research on genomic selection (GS) has focused on predicting unphenotyped lines. GS can also improve the accuracy of phenotyped lines at low heritability, e.g., in a preliminary yield trial (PYT). Our first objective ...
High-throughput SNP genotyping with the GoldenGate assay in maize
Single nucleotide polymorphisms (SNPs) are abundant and evenly distributed, and they have become an ideal marker system for genetic research in many organisms. Several high throughput platforms have been developed that ...
Genome-wide association analysis for nine agronomic traits in maize under well-watered and water-stressed conditions
Drought can cause severe reduction in maize production, and strongly threatens crop yields. To dissect this complex trait and identify superior alleles, 350 tropical and subtropical maize inbred lines were genotyped using ...
Relationship of line per se and testcross performance for grain yield of tropical maize in drought and well-watered trials
To optimize the efficiency of maize (Zea mays L.) drought breeding, the ability to predict testcross performance (TP) under drought stress using line per se performance (LP) of the parental inbreds would be useful. We ...
