MORPHOLOGICAL PROPERTIES AND PHENOLOGY OF THE GIANT (“ÓRIÁS”) TYPE APRICOT VARIETIES AND THEIR FERTILITY RELATIONS

There are four apricot varieties grown in Hungary derived from local selections known to bear fruits of giant (60 – 100 g) size: Ceglédi óriás, Nagykörösi óriás, Szegedi mammut and Ligeti óriás.
Being morphologically similar, they seem to be closely related to each other.
The detailed study of the morphology (of leaves and fruits) and phenology (of blooming and ripening dates) as well as the fertility relations was aimed to find out the degree of kinship between the varieties in question.

It was stated that the value of morphological traits is variable from the taxonomic point of view.
The most important signs of common origin were the time of blooming and the leaf size.
Less valuable are the date of maturity and the size of fruit because of their variability.
In the literature Szabó and Nyéki (1989) published the first proof of inter-incompatible relation between apricot varieties.
This should be considered as an argument of close genetic relation between those "giant" varieties of apricots.

The first three varieties, Ceglédi óriás, Nagykörösi óriás and Szegedi mammut are closer related in blooming and ripening date, as well as in size of fruit to each other than the variety Ligeti óriás.
