Abstract
We studied the pattern of variation of 19 morphological andphysiological characteristics of leaves and their phenotypicplasticity in 18 Mexican coconut populations experimentally grownunder similar conditions and in the presence of LY. The resultsshowed: (a) the existence of five ecotypes differentiatedby characteristic means and plasticity of these characteristics:Atlantic Tall, Pacific Tall 1, Pacific Tall 2, Pacific Tall 3 andMalayan Yellow Dwarf (MYD); (b) thecharacteristics that best differentiate the five ecotypes were: leaflength, number of leaves produced per unit time, and percentage ofproximal rachis in leaf; (c) the ecotypes correspond withpopulation groups previously observed in a study of morphologicalcharacterization of fruit in situ. Pacific Tall2 and MYD exhibited high resistance to LY and valuable morphologicalcharacteristics making them useful as parents in hybridizationprograms.
