Quantification of f loral abnormalities in a population generated from sexual polymorphism aiming at recurrent selection in papaya

ABSTRACT The aim of this study was to estimate the percentage of deformed fruits (carpelloid, pentandric, and bananoid), summer sterility, repeatability coefficients, and correlations among the variables for floral abnormalities; and select genotypes withthe lowest incidence of deformed fruits and s...
