Suitability of testers to characterize provitamin a content and agronomic performance of tropical maize inbred lines

Frontiers in Genetics, 2022
Vitamin A deficiency poses health risks for children, pregnant women, and nursing mothers in sub-Saharan Africa (SSA) and Southeast Asia. Provitamin A–biofortified maize varieties can contribute to minimizing the adverse effects of vitamin A deficiency ...

Gene-Editing-Mediated Enhancement of Carotenoid Compound Accumulation in Common Wheat Grains [PDF]

Foods
Common wheat (Triticum aestivum L.) is a staple food crop for humans, yet it primarily accumulates the non-provitamin A carotenoid lutein and exhibits limited natural variation in provitamin A β-carotene among its various accessions.

Heterotic grouping of provitamin A-enriched maize inbred lines for increased provitamin A content in hybrids

BMC Genomic Data, 2023
Background The establishment of heterotic groups of inbred lines is crucial for hybrid maize breeding programs. Currently, there is no information on the heterotic patterns of the Provitamin A (PVA) inbred lines developed in the maize improvement program

Variability of carotenoids in a Musa germplasm collection and implications for provitamin A biofortification

Food Chemistry: X, 2019
Bananas are important staples in tropical and sub-tropical regions and their potential as a source of provitamin A has recently attracted attention for biofortification. A collection of 189 banana genotypes (AAB-plantains, M. acuminata cultivars and bred
