Abstract
ATALAYA, Melissa Rabanal and HOYOS, Alicia Medina. Study comparative of the characteristics agronomic and chemical of three cultivars of purple corn in Peru. Rev. Mex. Cienc. Agríc [online]. 2022, vol.13, n.6, pp.953-964. Epub Feb 24, 2023. ISSN 2007-0934. https://doi.org/10.29312/remexca.v13i6.3019.
In Peru, due to the great geological and climatic diversity, there are different localities where agronomic and chemical research on purple corn has not yet been carried out. Therefore, the objective of the present research work was to evaluate yield, morphological and chemical characteristics of three varieties of purple corn, which were: INIA-601, an experimental variety called MM and Canteño, sown in five localities of the Departments of La Libertad and Cajamarca, located in northern Peru. Agronomic variables, yield and anthocyanin content in the cob and bracts were evaluated. The results showed that the best locality was Shaullo, with the cultivars of INIA-601 and Canteño, followed by MM, with yield values of 1.7, 1.6 and 1.6 t ha-1, respectively, with averageable values of plant height of 1.7 m, ear height of 0.76 m, prolificacy about 1, amount of anthocyanins in the cob of 4.8 mg g-1 and in the bracts of 1.6 mg g-1, and in ear rot, INIA-601 and Canteño obtained low and very close values of 5.9% and 5.4%, respectively; while MM, 9.6%.
