Hello,
Because I come from the Netherlands, I give my reaction in English. But it is no problem for me to read German.
On the following page on our website: *********
we give explanation about the "so called" interspecific variety 'Aprimira'. Our website is written in Dutch, but I hope that it is possible for you to understand this, or maybe you can translate our website into readable German with any toolbar-utility.
The essence of the story is:
(1) 'Aprimira' is the same as 'Aprikola', is the same as 'Miracose'
(2) 'Aprimira' is NOT an interspecific cross between plum and apricot. It is just a normal plum !
It is claimed that 'Aprimira' originated from an interspecific cross between the European cultivated plum Prunus domestica 'Mirabelle von Herrenhausen' and an apricot.
Because the seedling that grew from this crosspollination looked somewhat like an apricot, it was supposed that an interspecific cross took place. But from further investigations was discovered that 'Aprimira' is just a normal European cultivated plum (Prunus domestica) and that there is not any genetic content of apricot (Prunus armeniaca).
The flower of 'Mirabelle von Herrenhausen' were the crosspollination was made on, should have been contaminated with pollen from any other unkwown variety of normal European cultivated plum (can also be self-pollination). So, not an apricot but any normal plum was the father. Thus, 'Aprimira' should be considered as a variety of mirabelle, not as cross between plum and apricot !
From the beginning, I wondered if it could be correct that 'Aprimira' originated from interspecific origin. After all, the European cultivated plum is hexaploid (2n = 6x = 48), while the apricot is diploid (2n = 2x = 16). Moreover, the genome of Prunus domestica and Prunus armeniaca are not of equal origin. It is very unlikely that a very fertile cross between these two species can occur in the first generation.
Kind regards, Marcel Joosten.
