AbstractThe correlations between cherry yield and morphological characters of trees were calculated for 16 samples of Puerto Rican and Columnaris varieties of Coffea arabica L. In the Puerto Rican variety, yield was positively and significantly correlated with circumference of main stem at ground level in all the 11 samples. Yield was also positively and significantly correlated with width of canopy, length of primary lateral branches, and number of nodes per primary lateral branch, in more than half the samples. In the Columnaris variety, cherry yield had a positive and significant correlation with the circumference of the main stem at ground level in all the five samples. Yield also had positive and significant correlation with height of tree, width of canopy, and number of secondary lateral branches per primary lateral branch, in more than half the samples. Circumference of stem at ground level and width of canopy were the main tree characters correlated with yield in both varieties.
