- Abstract
The study of the diversity of Luffa cylindrica may allow specific screening for different applications, aiming at the use and improvement of the species. Molecular data and thirty morpho-agronomic descriptors were used in multivariate analyzes to characterize 24 bushing accessions from seven Brazilian states. The results showed that the accessions under study have a wide potential variability for all the morpho-agronomic characters analyzed. The characters that most contributed to the divergence between the accessions were the fruit length (62.32%) and the apical circumference of the fruits (19.70%). AFLP markers were efficient in grouping the bushing access from different Brazilian regions and showed 66.8% of polymorphism. The clustering obtained from the joint analysis of molecular and morpho-agronomic data separated the accessions into four groups and was consistent with the Bayesian cluster analysis in the separation of accessions collected in the North with those prospected in the other Brazilian regions.
