PRODUCTIVE AND PHYSICAL QUALITY PARAMETERS OF INTERCLONAL COCOA PROGENIES (Theobroma cacao L.)

Abstract:

This research was carried out at the Experimental Farm" La Represa", during the years 2012 to 2014. The behavior of 21 improved progenies of cocoa T. Nacional type was evaluated, including control of Trinitario origin (JHVH-10), a completely randomized block design was used within a bi-factorial, with four replications, using the Tukey multiple range test (P≤ 0.05). The following variables were evaluated: number of vegetative witches' brooms, percentage of diseased ears, number of healthy fruits, as well as estimated yield, and seed and ear index. The outstanding cross was DICYT-H-253, which presented the best yield kg/ha/year; DICYT-H-270 stood out as the progeny with the highest number of healthy ears, while DICYT-H-258 presented the highest number of ears with witches' broom. However, in the quality indexes, the crosses in terms of the cob index were DICYT-H-267 and DICYT-H-268. In the same way, DICYT-H-257 and DICYT-H-260 presented the highest seed index in terms of the number of kernels in 100 g, proving the productivity and quality of the central zone of the Ecuadorian coast.
