In order to determine the seed/fruit relationship in the ‘Colombia’, ‘Kenya’ and ‘South Africa’ ecotypes of the cape gooseberry, samples of fruits from an orchard located in Nuevo Colon (Boyaca; 2,464 m a.s.l., 15oC average temperature and 980 mm annual precipitation) were taken. The plant arrangement was 2.5 x 1.8 m and fruits were harvested after physiological maturity (stage 3 according to Icontec). For each fruit, the variables: fresh weight, equatorial diameter, polar diameter, number and weight of seeds were measured and then the variables seed weight and seed index (number of seeds/100 g fruit weight) were calculated. Analysis of the principal components showed that the corresponding data clearly separated the ecotype Colombia from the other ecotypes. ‘Colombia’ presented significant differences for the averages of fresh weight, polar diameter and equatorial diameter per fruit, having smaller values than the other two ecotypes, but a higher seed index, whereas the Kenyan and South African ecotypes only presented statistical differences for the variable seed weight per fruit. The most important relationship was between the fruits’ fresh weight and the weight of seeds per fruit found in the Colombian ecotype, while the relationship between fruit weight and seed number/ fruit was less so. Additional key words: fruit weight, fruit diameter, seed weight, seed index. Fecha de recepcion: 03-02-2010 Aprobado para publicacion: 02-06-2010
