Background and objectivesMaize protein lacks essential amino acids such as methionine, lysine and tryptophan. Limited information exists on composition and variation of kernel methionine. This study assessed methionine variability and its relationship with lysine and tryptophan in 48 maize inbreds at three locations.FindingsANOVA revealed significant variation for kernel methionine (0.031‐0.305%), lysine (0.118‐0.389%) and tryptophan (0.014‐0.090%). CML591 (0.305%), CML596 (0.286%) and CML421 (0.284%) showed highest methionine content. Average methionine contents were comparable in QPM (0.156%) and normal (0.150%) lines. Methionine showed no correlation with lysine (r=0.001) and tryptophan (r=0.032), while lysine and tryptophan exhibited a strong positive correlation (r=0.740). CML165 (methionine: 0.272%, lysine: 0.320%, tryptophan: 0.090%), CML186 (methionine: 0.254%, lysine: 0.389%, tryptophan: 0.083%) and HKI163 (methionine: 0.252%, lysine: 0.331%, tryptophan: 0.084%) were the promising genotypes considering all the three amino acids.ConclusionsMulti‐location experiments revealed genetic variation in methionine, lysine and tryptophan among the 48 inbreds. No negative correlation between the amino acids indicates the possibility of developing cultivars high in methionine, lysine and tryptophan.Significance and noveltyIdentified nutrient rich inbreds will serve as valuable germplasm in maize biofortification program. This is the first report on methionine variability and its relationship with lysine and tryptophan in subtropical maize.This article is protected by copyright. All rights reserved.

“…Traditional maize is also deficient in two other essential amino acids, such as lysine and tryptophan (Hossain et al, 2023). Besides serving as building blocks for protein synthesis, they function as precursors for several neurotransmitters and regulators of metabolic pathways (Yadava et al, 2018).…”

Development of non-conventional hybrids (NCHs) responds to the demand for the Elotes Occidentales 'EO' race for production of pozole. The effect of: crop cycle (2019, 2020 and 2021) on physical characteristics, flowered grain quality and phytochemical content of two HNC (Pz1 and Pz2) of pozolero maize, as well as the effect of the presence or absence of pedicel, type of pollination (open and controlled, 2019), and progenitor lines (female and male, 2020) on flowered grain quality and content of phytochemical compounds were evaluated. Size, hardness, color, total phenols and anthocyanins in unprocessed grain were determined, and yield, volume and puncture strength in flowered grain. Results were analyzed with a factorial arrangement in a completely randomized design. There were significant differences (p≤0.05) in most of the variables studied by effect of crop cycle and genotype. NCHs had large grains (40 g 100 grains-1), soft endosperm (IF&gt; 60), pink-purple color, and phenol and anthocyanin contents similar to those reported for the 'EO' race. The presence or absence of the pedicel did not affect flowered grain quality. Controlled pollination favored anthocyanin synthesis. The anthocyanin content of NCHs was determined by the female line. Thermal processing reduced anthocyanins by 60%; however, they leached into the flowering broth, so that the pozole made from NCHs improves the nutraceutical value of the pozole, relative to that of pozole made with Cacahuacintle maize.

Development of non-conventional hybrids responds to the demand for the Elotes Occidentales land-race for production of pozole. The effect of growing cycle (2019, 2020, and 2021) on physical characteristics, flowered grain quality, and phytochemical content of two non-conventional hybrids of pozolero maize, as well as the effect of the presence or absence of pedicel, type of pollination (open and controlled, 2019), and parents (female and male, 2020) on flowered grain quality and content of phytochemical compounds, were evaluated. Size, hardness, color, total phenols, and anthocyanins in unprocessed grain were determined. Yield, volume, and puncture force were measured in flowered grain. Results were analyzed with a factorial arrangement in a completely randomized design. There were significant differences (p ≤ 0.05) in most of the variables studied by effect of crop cycle and hybrid. Non-conventional hybrids had large grains (40 g 100 grains−1), soft endosperm (flotation index > 60), pink-purple color, and phenol and anthocyanin contents similar to those reported for the Elotes Occidentales land-race. The presence or absence of the pedicel did not affect flowered grain quality. Controlled pollination favored anthocyanin synthesis. The female parent determined the anthocyanin content of non-conventional hybrids. Thermal processing reduced anthocyanins by 60%; however, they leached into the flowering broth, so that the pozole made from non-conventional hybrids can have improved nutraceutical value, relative to that of pozole made with Cacahuacintle land-race.
