SWEET CHERRY VARIETIES

For good cherry yields, appropriate pollination must be guaranteed. Only a few, mostly newer breeds (Sweetheart, Lapins, Celeste...) are self-fertile.

It is a well-known fact that not all varieties are compatible with each other.

Scientific institutes have found out that each variety has 2 sterility factors (S-alleles). If a pollen with the same S alleles reaches a flower, it cannot grow through to an ovum in the ovary. Only varieties with different S values are compatible. If only one of the S values is different, only 50% of pollen can be pollinated. Since, depending on the flowering strength, less than half of the flowers usually have to become cherries for a normal yield, it is usually sufficient if the type of pollinator differs in one S-allele.

In addition, the blossoming process of the variety must more or less coincide with the one of the pollinator. However, if a variety ripens relatively early it does not mean that its time of blooming is also early. Sweetheart, for example, flowers very early and ripens very late.

That is why we have listed both, the S-allele and the blooming date of the respective variety, in the following variety description. In order to enable sufficient pollination, the type of pollinator should have at least one differing S-allele; concerning the blooming time it should only differ by one category (e.g. medium-late blooming for late blooming) and the pollinator tree should not stand more than 30 m away.

BURLAT

S-alleles: S3 S9 Blooming time: medium early

Ripens in the second week of the cherry season, i.e. in our country in the first decade of June, and is the most widely planted early variety in the world, although it does not yet have the same high transport rigidity, burst resistance and yield as many late varieties. The fruit is large, firm fleshed, juicy and sweet; short-stalked; very attractive, aromatic, tasty early heart cherry; the tree grows strong and steep;

MERCHANT

S-alleles: S2 S4 Blooming time: medium early

Matures between Burlat and Celeste and is very high-yielding. The fruit size and quality is equivalent to that of Burlat with better burst resistance. The tree grows medium strong and spindle-friendly, very easy to cultivate in general.

GIORGIA

S alleles: S1 S13 Blooming time: Medium early

ripens shortly after Merchant with a very good pulp firmness. The fruits are large (7-9g) and moderately burst resistant with very good fruit quality. The tree grows on axels with many weak, rich-bearing branches; this requires a strong pruning of the fruitwood to promote the size of the fruit. The blossom is self-sterile and moderately early.

KORDIA

S-alleles: S3 S6 Blooming time: moderately late

ripens in the sixth cherry week, late June to early July; it is very big in size, brown-red in colour, very firm and crisp, harmonious in taste and aroma; very high burst resistance; Kordia usually hangs loosely and evenly spread on the tree, which causes a rapid drying-off of the fruits after rainfall and a very uniform fruit size; early start of yield and high yield. These advantages have made Kordia our most important variety in the medium-late ripening period for commercial fruit growing, despite its sensitivity to frost.

IRENA®

S-alleles: S4 S6' Blooming time: very late

This Czech new variety from Holovusy ripens at the same time as Regina, blossoms just as late, but has 2 other S alleles. These characteristics and the fact that she looks amazingly similar to Regina make her particularly interesting as a pollinator for Regina in commercial cultivation, if you plan every 10th tree in a row as a pollinator but want to harvest it at the same time. The fruits are very attractive, heart-shaped, dark red - shiny and with a fruity aroma. The tree grows medium strong - strong, branches well, somewhat more upright than Regina.


SWEETHEART® SUMTARE

S-alleles: S3 S4' Blooming time: very early

ripens after Regina in the eighth cherry week and belongs to the elite of the brand new cherry varieties. Sweetheart is large (around 9.5g), strongly red in colour and of excellent taste; due to its very high fertility the tree has an upright but beautiful habitus; self-fertility guarantees very high and regular yields; resistance to burst, fruit quality and storability offer this novelty a secure position in the future cherry assortment.
