“CAERI 1” y “CAERI 2”, Nuevos clones de cacao (Theobroma cacao L.), una alternativa para las zonas cacaoteras de México

Abstract

Objective: Describe the new clones of cacao with tolerance to moniliasis and good yield.

Design/methodology/approach: The cacao clones "CAERI 1" and "CAERI 2" are the product of the crossing of international clones that are characterized by their resistance to moniliasis and black spot, the main diseases in Mexico. The clone CAERI 1 is a product of the PA 169 x UF-273 cross and CAERI 2 of the cross H-31 x UF-273. Families of complete siblings were evaluated for yield and tolerance to moniliasis and finally individuals were selected who were clonally propagated for their agronomic evaluation in the Rosario izapa Experimental Field of INIFAP.

Results: According to the evaluations made, both at the level of families of complete siblings and the individuals selected within each family, it was obtained that the clone CAERI 1 was characterized by its tolerance to moniliasis and good performance and CAERI 2 by its moderate tolerance to moniliasis and high performance

Limitations on study/implications: The clones are in the phase of establishment of clonal gardens for their massive propagation and in evaluation in different plots of producers.

Findings/conclusions: Two cocoa clones are available as an alternative for the renewal of cocoa plantations in Mexico
