thickness, only population Vinga is distinctly significant superior to the control landrace
Cristal. In other populations, the pulp is thinner, in 9 cases having the statistic assurance. If
fruit pulp weight is determined, more populations are superior to the control. The most
valuable is population Temereşti I. concerning mentioned quality traits, studied
populations are not so valorous due to thin pulp which is not desirable for fresh
consumption or processing.
Seed production is not a yield component, but it may have an impact in multiplication
process of this species. High quantity of seed in fruit can be unfavorable for pulp
development since the plant directs the nutrients to the seeds instead to the pulp. In
comparison to the control landrace Cristal, most of the populations presented higher seed
number, and superior weight. Such a situation is typical for wild and extensive forms.
Inferior values were not registered in comparison to the control.(table 3.)

Conclusions
1. Studied collection is valorous in breeding processes for fruit size. Landraces with big
fruits are recommended for cultivations in provenience area, being adapted to specific
climatic conditions. Among evaluated populations, Temereşti I and Şiria are
