The timing of blooming in spring is highly crucial for temperate zone tree fruit production. In this study, we aimed to investigate floral development using the all parents and full-sib offsprings of two different crossing combinations ('Kaşel 37' × "Delbarestivale and 'Kasel 41' × 'Williams' Pride ). Assessments of variability in floral development have been done according to a numerical assessment scheme defined by ten stages (stage 0-9). The assessments were conducted three different dates, early (21 04). intermediate (28 04). and late (05 05). The results showed significant variations for floral development among the 273 genotypes. In particular, the genotypes 326, 340, 369, 88 and 146 were found as superiors for floral development. The broad sense heritability (hb 2) for floral development was reliable on the first assessment] date, with no reliability on the other assessment dates. Our results would be use fill to geneticists and breeders.
