“…Mean squares in analysis of variance for GCA, SCA effects along with additive and non‐additive variances, were used for estimating the gene action of carotenoid traits in maize endosperm. Both additive and non‐additive gene actions were reported for carotenoid‐related traits (α‐carotene, β‐carotene, β‐cryptoxanthin and provitamin A concentration) in maize endosperm (Chander et al., ; Egesel, Wong, Lambert & Rocheford, ; Halilu, Ado, Aba & Usman, ; Suwarno, Pixley, Palacios‐Rojas, Kaeppler & Babu, ).

Vitamin A deficiency is widely prevailing in children and women of developing countries. Deficiency of vitamin A causes night blindness, growth retardation, xerophthalmia and increases the susceptibility against epidemic diseases. Among different interventions of overcoming malnutrition, biofortification is the most acceptable and preferred intervention among researchers, growers and consumers. Maize is grown and consumed in those regions where vitamin A deficiency is most prevalent; thus, targeting this crop for provitamin A biofortification is the most appropriate solution.Different breeding strategies including diversity analysis, introduction and stability analysis of exotic germplasm, hybridization, heterosis breeding, mutagenesis and marker-assisted selection are practised for exploring maize germplasm and development of provitamin A-enriched cultivars. Genome-wide association selection and development of transgenic maize genotypes are also being practised, whereas RNA interference and genome editing tools could also be used as potential strategies for provitamin A biofortification of maize genotypes. The use of these breeding strategies for provitamin A biofortification of maize is comprehensively reviewed to provide a working outline for maize breeders. Retinol activity equivalent (RAE) is the best option to express the dietary reference intake (DRI) of vitamin A because bioavailability is accounted in this way. Recommended DRI for females is usually 700 RAE, for pregnant females 770 RAE, for lactating females 1,200-1,300 RAE, for children 400-500 RAE and for males 900 RAE. One

“…Halilu et al. () reported the zero value of additive variance for α‐carotene, β‐carotene, β‐cryptoxanthin and provitamin A contents in maize endosperm using diallel analysis. However, additive variance was predominantly prevailing for non‐provitamin A carotenoids (lutein and zeaxanthin).…”

5Uma das estratégias apontadas para o combate aos déficits nutricionais é a biofortificação de alimentos, uma técnica que visa aumentar o teor de nutrientes específicos em alimentos básicos. Entretanto, nos últimos anos, questionamentos acerca de suas potenciais consequências negativas ao meio ambiente e à Segurança Alimentar e Nutricional passaram a ser levantados. Diante do exposto, o presente artigo objetivou realizar um levantamento bibliográfico sobre a biofortificação de alimentos, acerca de suas questões nutricionais, culturais, econômicas e ambientais e suas principais controvérsias, utilizando como ferramenta as bases de dados Scielo, Web of Science, Pub Med, Portal de Periódicos Capes e Science Direct, Biblioteca Digital de Teses e Dissertações da USP e o Google Acadêmico. Embora a biofortificação tenha, em muitos casos, se mostrado um caminho promissor para melhorar os teores de nutrientes e vitaminas nos diversos itens alimentares é verídico afirmar que a mesma apresenta diversos aspectos negativos. Logo, é imprescindível a realização de estudos que visem elucidar seus amplos efeitos, contemplando as esferas econômica, política, social e nutricional. Enquanto isso, estratégias que visem solucionar as principais causas da insegurança alimentar são as mais recomendadas para a solução do problema da fome, seja ela oculta ou crônica.Palavras-chave: biofortificação de alimentos, segurança alimentar e nutricional, fome oculta, sustentabilidade na alimentação. Food Biofortification: problem or solution?Biofortification is one of the indicated strategies for fighting nutritional deficits, being a technique that aims the increase on the contents of specific nutrients in staple foods. However, there have been questions about the potential negative consequences it brings not only to the environment but also to the Food Security and Nutrition. The present work aimed at a bibliographic survey about biofortification, broaching questions about the nutritional, cultural, economic and environmental aspects related to this theme and the main controversies about it.

“…The plant biofortification mainly is used in micronutrient malnutrition or enriching plants with desirable nutrients or against hidden hunger (El-Ramady et al 2016b;Singh et al 2016;de Valença et al 2017;Díaz-Gómez et al 2017). This biofortification process also could cover several strategic or staple crops such as rice (Boldrin et al 2013;Shivay et al 2016;Chen et al 2017;Gontia-Mishra et al 2017), wheat (Shaikh and Saraf 2017), maize (Halilu et al 2016;Liu et al 2017;Sharma et al 2017), barley (Bityutskii et al 2017), beside other crops like Brassica sp. (Barrameda-Medina et al 2017), pea (Poblaciones and Rengel 2016), common bean (Ram et al 2016), potato (Kromann et al 2017;White et al 2017) and sweet potato (Laurie et al 2015).…”

“…Concerning plant biofortification, it could be defined as producing different staple foods containing in their edible parts higher content of bioavailable minerals (Fe, Cu, Zn, Ca, Se, I, etc. ), and some nutritional compounds such as folate (Olivares et al 2015;Strobbe and van der Straeten 2017), thiamin or vitamin B1 (Goyer 2017), vitamin B6 (Fudge et al 2017), provitamin A (Halilu et al 2016;Giuliano 2017) and vitamin E (Mène-Saffrané and Pellaud 2017). The plant biofortification mainly is used in micronutrient malnutrition or enriching plants with desirable nutrients or against hidden hunger (El-Ramady et al 2016b;Singh et al 2016;de Valença et al 2017;Díaz-Gómez et al 2017).…”

IT is well known that, sustainable agriculture is an important part of sustainable development. This sustainable agriculture should lead to achieve food security and maintain the biodiversity of natural ecosystems. Sustainable agriculture also should have definitely a global perspective. The conservation of both soil and water resources, therefore, is considered an essential prerequisite as well as the efficient use of mineral and organic fertilizers. This could be achieved by improving agro-technology and better understanding of the essential processes in soils. Foliar application of agrochemicals including fertilizers should be improved seeking for the sustainability of agriculture. The present review will focus on the effects of foliar application of nutrients for plant nutrition and its biofortification. Proper timing of foliar application, endo-, exogenous and environmental factors affecting foliar nutrition, influence of mineral fertilizer nutritional quality of staple food crops and finally nano-foliar nutrition as well as postharvest quality of crops will be also highlighted.
