Abstract

VALENCIA, Adelaida Stephany Hernández et al. Phenotypic characterization of the Jica-TH-19 avocado variant for Central Mexico. Rev. Mex. Cienc. Agríc [online]. 2024, vol.15, n.3, e3679.  Epub May 28, 2024. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v15i3.3679.

The variant called JICA-TH-19, located in the Experimental Orchard of the ‘Presidente Juárez’ Faculty of Agrobiology, was selected in 2021. Avocado trees descended from the original Hass variety from the state of California, USA, established during the 1970s in the INIFAP orchard in Uruapan, were used as reference material (control). Segregating materials were planted in 2016 and characterized between 2018-2022, in an experimental orchard located 4 km from Uruapan, Michoacán and its coordinates are: 19° 23’ 54.3” north latitude, 102° 03’ 12.9” west longitude, and an altitude of 1 636 m. The objective was to characterize morphologically variant genotypes of original ‘Hass’ avocado that have the potential to be exploited commercially in the avocado belt of Michoacán. The characterization of the trees and their vegetative and reproductive organs was carried out based on the Manual of descriptors for avocado (CICTAMEX, 1991), published by the Sánchez Colín Foundation with the support of the standard format followed by the International Board for Plant Genetic Resources (IBPGR).
