Caracterización morfoagronómica de accesiones de yuca (Manihot esculenta Crantz) del CATIE
Este set de datos contiene información de caracterización de 37 (de un total de 157) accesiones de yuca conservadas en CATIE. La caracterización. La caracterización morfológica se realizó durante los años 2009 y 2010, siguiendo los descriptores descritos por Fukuda et al. (2010) y hace parte del trabajo de investigación de Luis Torres, estudiante del programa de maestría de CATIE.

Record the most frequent occurrence. Yucca green mite damage can obscure this trait, so it is better to score earlier rather than later. Note a leaf from the middle of the plant
Observe three months after planting
Leaf taken from a medium height position
Leaf taken from a medium height position
Observe from the middle third of the plant. Make a small shallow cut and peel off the epidermis
Observe from the middle third of the plant. Measure two leaves/plant. Express in cm
The observation should be made in the upper 20 cm of the plant
Measure the vertical height from the ground to the first primary branch. Zero = no branching. Ignore lateral branching. Express in cm. Record measurements for at least three plants
Measure before harvest. Measure the vertical height from the ground to the top of the canopy. Express in cm
Measure on a mature root. This can be affected by nematodes and/or cassava brown streak virus diseases
Record the number of branch divisions. Zero (0) for no branching. Ignore if branching laterally
Record the most frequent occurrence
Observe from the middle third of the plant
Record the most frequent occurrence
At least one flower on each plant. Scoring should be repeated at regular intervals until harvest to determine if flowering occurs. Record the presence of flowering and the date of observation
The root must be touched
Evaluate on five leaves and take the predominant number of lobes
Record the most frequent occurrence
Expressed in kg/ha
Expressed in kilograms
Root shape
Consider a 20-centimeter commercial stake
Measure only main roots
