Abstract

Fifty plants of miracle fruit at the farm in Brgy. Mabacan, Calauan, Laguna was assessed for variation based on ten qualitative traits: (tree canopy shape, leaf orientation, leaf color, leaf tip, peel color, fruit shape, fruit tip, flesh color) and thirteen quantitative traits: (plant height, canopy diameter, stem diameter, leaf length, leaf diameter, fruit polar diameter, fruit equatorial diameter, fruit weight, seed length, seed diameter, seed weight, flesh + peel weight, and total soluble solids). Data was subjected to Frequency Distribution Analysis. Distribution of qualitative traits showed that sampled seedlings population of miracle fruit was dominated by a spreading canopy shape, erect leaf orientation, green leaf color, acute leaf tip, red peel color for the fruit, ellipsoid fruit shape slightly pointed fruit tip and pale red flesh color. Morphological diversity was based on Shannon-Weaver (H?) diversity index. Index calculated for each parameter revealed that leaf orientation (H? =0.96), plant height (H? =0.93) and east-west canopy diameter (H? =0.89) showed the highest diversity indices. Fruit shape (H?=0.21) and leaf tip (H?=0.30) showed the lowest diversity indices which indicated a low phenotypic variability for these traits. This entire collection of miracle fruit study had an overall mean diversity index of 0.67 which is indicative of medium variation.
