LUNA GARCIA, Laura Raquel et al. Agronomic and nutraceutical behavior of F2 populations developed of interracial crosses of pepper. Rev. Mex. Cienc. Agríc [online]. 2021, vol.12, n.1, pp.23-36. Epub 21-Fev-2022. ISSN 2007-0934. https://doi.org/10.29312/remexca.v12i1.2423.
Every day it is more difficult to satisfy the world food demand, for this reason the importance of working in the development of new varieties of high yield and fruit quality, taking advantage of the genetic resources of Mexico, for the development and use of superior varieties that allow to reduce the production costs of protected agriculture systems since, in Mexico in these systems a significant percentage comes from foreign companies at high costs. However, small producers sow creole seed of low yield and fruit quality. In this work, the RTF and its components (NFP, PPF), in addition to some quality characters (CAA, CT and CAPs) and agronomic (ADP, DBT, DAF, and DAC) of nine pepper hybrids in their F2 generations and their respective parents, which were established in a greenhouse, under an experimental design complete random blocks with three replications. The variance analyzes exhibited significant differences (p< 0.01) between parents and F2 populations in all the variables studied. In RTF, the F2 populations (P1,7 and P3,4) exceeded their F1 by 7 and 5% respectively, the latter being the one that presented the highest RTF in this generation with 2 764 g plant-1. All F2 populations presented intermediate amounts and positive values in DEP in CT, CAA and CAPs. Concluding that in the F2 generation there were promising populations for the development of new varieties, since they increased yield and fruit quality from F1 to F2, with an estimated yield greater than 100 t ha-1.
