The low yield potential of most biofortified maize is a barrier to its full adoption and reduces curb various macro- micronutrient deficiencies highly prevalent in low-income regions the world, such as sub-Saharan Africa (SSA). By crossing inbred lines with different nutritional attributes zinc (Zn), provitamin A protein quality, breeders are attempting develop agronomically superior stable mul...

Epistasis plays an important role in genetics, evolution and crop breeding. To detect the epistasis, triple test cross (TTC) design had been developed several decades ago. Classical procedures for the TTC design use only linear transformations Z(1), Z(2) and Z(3), calculated from the TTC family means of quantitative trait, to infer the nature of the collective additive, dominance and epistatic ...

and a decreasing supply (Golbitz, 1999), suggest that oil productivity of soybean should be improved. Previous Protein meal and oil are the two commodities produced from research indicated that seed oil concentration is consoybean [Glycine max (L.) Merr.] that give the crop its value. Increasing seed concentrations of either or both may add value. Objectives trolled by multiple genes with addit...

An efficient hybrid breeding program defines and utilizes a few heterotic groups. Objectives of this study were to determine genetic diversity alignment South Africa maize inbred lines collection towards tropical temperate testers. Forty-four genotyped with 56,110 single nucleotide polymorphism (SNP) markers. A total 40 crossed two line Due seed shortages, testcross hybrids containing 14 18 use...

The tar spot complex (TSC) is a devastating disease of maize ( Zea mays L.), occurring in 17 countries throughout Central, South, and North America the Caribbean, can cause grain yield losses up to 80%. As from continue intensify Central America, Phyllachora maydis , one causal pathogens TSC, was first detected United States 2015, 2020 Ontario, Canada. Both distribution due TSC are increasing, ...
