| English abstract | Twelve experimental triploid hybrids were evaluated to estimate heterotic effectsfor some pIam andfruit traits in triploid watermelon (Citrullus lanatus). Tiffany, a triploid hybrid was I/sed as standard cultivar. The experiment in a randomized block design was carried out in three replications at the Experimental Station of Embrapa Semi-Árido in Petrolina, state of Pernambuco. Thefollowing traits were evaluated: earliness, prolificacy, main stem length, fruit weight, soluble solid content, rind thickness,flesh color, and hollow heart disorder. All evaluated traits presented significant variability among the hybrids. Mid-parent heterosis effects were found as well as the standard cultivar ranging from negative to positive values attaining up to 300% prolificacy in some cases. The tetraploid lines should be improvedfor several traits in order to produce earlier triploid hybrids with more compact plants andfruits without the hollowheart disorder |
