Genetic dissimilarity, selection index and correlation estimation in a melon germplasm

ABSTRACT The success of breeding programs depends on genetic variability. Individuals selected based a few traits may be limitation. One alternative is the use nonparametric indices. However, there no information selection indices in melon germplasms. present study aimed to estimate dissimilarity germplasm and select potential parent plants for future programs. material consisted 37 accessions. assessed were fruit diameter length, length cavity total soluble solids. Genetic was by multivariate analyses (UPGMA Tocher). Selection gain estimates analyzed comparing classic Smith-Hazel sum ranks diversity observed between variable that contributed most length. Simultaneous index better suited assessment. best accessions five variables simultaneously UFU07, UFU23, UFU09, UFU21, UFU28 UFU30.
