Menkir, A.Palacios-Rojas, N.Alamu, O.Dias Paes, M.C.Dhliwayo, T.Maziya-Dixon, B.B.Mengesha, W.Ndhlela, T.Oliveira Guimarães, P.E.Pixley, K.Rocheford, T.[Vitamin A-biofortified maize: exploiting native genetic variation for nutrient enrichment]Vitamin A-biofortified maize: exploiting native genetic variation for nutrient enrichment

The discovery and use of genetic markers associated with carotenoid levels can help to exploit the genetic potential of maize for provitamin A accumulation more effectively. Provitamin A carotenoids are classes of carotenoids that are precursors of vitamin A, an essential micronutrient in humans....


Azmach, G.Menkir, A.Spilane, C.Gedil, M.[Genetic loci controlling carotenoid biosynthesis in diverse tropical maize lines]Genetic loci controlling carotenoid biosynthesis in diverse tropical maize lines

Vitamin A Deficiency (VAD) is a major public health problem in Sub-Saharan Africa affecting 33 million preschool-age children. Enrichment of maize varieties with provitamin A could provide sustainable and affordable solution to VAD. This study was conducted to understand the extent of GEI effects...


Mengesha Abera, W.Menkir, A.Meseka, S.Bossey, B.Afolabi, A.Burgueno, J.Crossa, J.[Factor analysis to investigate genotype and genotype X environment interaction effects on pro-vitamin A content and yield in maize synthetics]Factor analysis to investigate genotype and genotype X environment interaction effects on pro-vitamin A content and yield in maize synthetics

Background: Biofortification of staple crops is a cost effective and sustainable approach that can help combatvitamin A and other micronutrient deficiencies in developing countries. PCR -based DNA markers distinguishingalleles of three key genes of maize endosperm carotenoid biosynthesis (PSY1, l...
