Characterization of maize germplasm grown in Eastern and Southern Africa : results of the 2004 regional trials coordinated by CIMMYT
The Summary Tables present grain yields averaged across sites with significant differences between entries, for each of the five to six environments. Data on agronomic performance such as anthesis date, plant and ear height, ...
Genome‑wide association analysis reveals new targets for carotenoid biofortification in maize
Key message Genome-wide association analysis in CIMMYT’s association panel revealed new favorable native genomic variations in/nearby important genes such as hydroxylases and CCD1 that have potential for carotenoid b ...

Formation of heterotic groups and understanding genetic effects in a provitamin a biofortified maize breeding program
Developing biofortified maize cultivars is a viable approach to combat the widespread problem of vitamin A deficiency among people for whom maize is a staple food. To enhance CIMMYT's provitamin A maize breeding efforts, ...
Divergent selection for resistance to maize weevil in six maize populations
Maize weevil (Sitophilus zeamais Motschulsky) is an important pest of maize (Zea mays L.) in the tropics, causing serious losses for many resource-poor farmers who store grain on-farm for use as food and seed. This study ...
Diallel analysis of grain yield and resistance to seven diseases of 12 African maize (Zea mays L.) inbred lines
Maize (Zea mays L.) is grown on 15 million ha in eastern and southern Africa. Several diseases are of common occurrence in the region and regularly result in significant yield losses. A collaborative regional disease nursery ...
Comparative intake of white- versus orange-colored maize by Zambian children in the context of promotion of biofortified maize
Background. Vitamin A deficiency is associated with poor health outcomes related to reproduction, growth, vision, and immunity. Biofortification of staple crops is a novel strategy for combating vitamin A deficiency in ...
Maize genotype and food matrix affect the provitamin a carotenoid bioefficacy from staple and carrot-fortified feeds in Mongolian gerbils (Meriones unguiculatus)
Biofortification to increase provitamin A carotenoids is an agronomic approach to alleviate vitamin A deficiency. Two studies compared biofortified foods using in vitro and in vivo methods. Study 1 screened maize genotypes ...
