Comportamiento de 50 familias de medios hermanos de Solanum quitoense Lam bajo selección recurrente

The present study was oriented towards the implementation of recurrent selection by half sibs as a basis for the breeding program of lulo de Castilla in the Andean zone of Narino. 50 families of half sib were evaluated in two locations (Florida and Yacuanquer), in order to select those that improved production, quality and crop productivity of lulo in the department of Narino. Trials were planted under randomized complete blocks design with two replications. Yield, fruit weight, seed weight per fruit, juice content, total soluble solids, titratable acidity and maturity index were evaluated. This first cycle of half sibs recurrent selection of lulo de Castilla was effective, since an increase was obtained in yield with 10,67 t ha-1, on the weight of fruit with 33,34 g and juice content with 18 ml for families LSCmmh22, LSCmmh06, LSCmmh36, LSCmmh32, LSCmmh44, LSCmmh08, LSCmmh42, LSCmmh45, LSCmmh34 and LSCmmh29, which obtained the highest rates of selection.
