The Mesoamerican region is center of origin, domestication, and diversification of maize. In this ecogeographic context, the objective was to evaluate the variation in the phenolic compounds, antioxidant activity and concentration of minerals in the grain of a population collection of yellow maize landraces from southeastern Mexico. During 2016, sa...

Common bean (Phaseolus vulgaris L.) is a basic staple product for the Mexican diet and gastronomy. It supplies proteins, carbohydrates, vitamins, fiber and secondary metabolites, as well as a wide range of mineral macro and microelements, such as Iron (Fe) and Zinc (Zn). Deficiencies of either element are associated to poor nutrition and health pro...

Native populations of pepper (Capsicum annuum L.) are highly heterogeneous and divergent, and some of them may be used as parents to formulate breeding strategies, that explore and exploit maximum heterosis from their genetic divergences. In this work, inter-population heterosis on agro-morphological traits and capsaicinoids was evaluated on interp...

... This may be related to the higher phenolic contents found in this study as was previously discussed. Lower total antioxidant values than those from current investigation were determined in Chilean (1307-1850 µmol TE/100 g DW, ABTS method) and Southern Mexican maize landraces with different kernel pigmentations (377-484 µmol TE/100 g DW, DPPH method) (47,64). In addition, comparable total antioxidant capacity has been observed in landraces from the Northeast of Mexico (2827-4264 µmol TE/100 g DW, ABTS method) and in diverse waxy maize genotypes grown in Thailand (average of 1096 and 3791 µmol TE/100 g DW with the DPPH and ABTS methods, respectively) (74, 75). ...
... Te highest value in this study was within the range as reported by Shaista et al. [2] in white maize (65.38% to 78.74%) but was higher than in yellow maize (60.23%) as reported by the same author. Diferent values of carbohydrates have been reported by diferent authors, and the highest content range is between 76% and 84% [2,41]. In this study, the highest value was reported in purple maize from Dedza (65.52%) and is within the published ranges [2,39,42]. ...
... Regarding its nutritional content, the protein content varies from 14 to 33%, being rich in amino acids such as lysine (6.4 to 7.6 g/100 g of protein) and phenylalaninetyrosine (5.3 to 8.2 g/100 g of protein), but with deficiencies in methionine and cysteine, despite this, the quality of cooked bean protein can become up to 70% compared to a protein of animal origin. Also, it has high concentrations of vitamins such as thiamine, riboflavin, and niacin and minerals such as phosphorus, iron, and zinc (Espinoza-García et al., 2016;Ulloa et al., 2011;Figueroa et al., 2015). On the other hand, peanuts (Arachis hypogaea Linn), known as groundnut, are botanically defined as legumes and it is the main legume consumed worldwide, having great economic importance in countries such as China, India, and the USA (Wang et al., 2021). ...
... heterosis, this parameter will always be important for breeding. Positive heterosis is desirable to increase the magnitude of traits like fruit or grain yield; on the other hand, if it were negative, the magnitude of the traits would decrease (Alam et al., 2004;Escorcia-Gutiérrez, Molina-Galán, Castillo-González, & Mejía-Contreras, 2010;Martínez-Martínez et al., 2014). ...
