Morphoagronomic characterization and genetic diversity of a Brazilian okra [ Abelmoschus esculentus (L.) Moench] panel

摘要: Okra [Abelmoschus esculentus (L.) Moench] has been neglected by breeders as few cultivars have released over the last years, which contributes to yield stagnation. Developing modern is key increase okra production. To provide information efficiently improve cultivars, this study aimed characterize and assess genetic diversity of a Brazilian collection using Ward-MLM (Modified Location Model) multivariate procedure. Both quantitative qualitative variables can be simultaneously considered in strategy. Forty-six accessions from active germplasm bank Embrapa Hortalicas open-pollinated ‘Santa Cruz 47’ were characterized according descriptors lists. Seven groups identified comprising seven, six, fourteen, five, two genotypes, respectively. Group VII was most distant relation other groups, probably because greatest vegetative development lowest fruit Variability observed for morphological traits. The grouping will useful conservation management crossing strategies. Leaf length, leaf width, petiole stem diameter at plant base, first flowering height contributed variation. variability verified suggests high potential breeding new cultivars.
