Breeding program

Our technical team establishes and controls 100% of our breeding program.

The breeding season lasts 3 months, during which a qualified team operates in the orchardsand trial blocks. Our main objectives are to complete the ranges of each proposed species (from April to September), and to work on new fruit’s innovation that will be launched in the future.

Thanks to our team’s work, about 50,000 new hybrids are planted each year.


Agricultural behaviour

The variety’s agricultural potential is studied and analysed for a minimum of 10 years, in the aim to observe its behaviour related to the climatic variations experienced each year (winter, dormant period, water, temperature contrast, etc.).

The full phenology of the variety is observed from the dormant season to the blooming period and the development of fruit.

It is also observed during the entire harvesting process and during its time in storage (up to 40 days).


The criteria for selecting new varieties include the following:
sweet and flavoured taste, attractive red colour, size, shape (round or flat), self-defence capacities from disease, firmness and self–fertility (apricots).

Each variety has to be easy to pick, easy to handle at the pack-house and have a long shelf-life for storage and transport. A constant annual production, related to economic profitability for growers, is also an essential criterion for selection.


Thanks to our collaborators and trial blocks all over the world, we are able to observe how each new variety adapts to a specific production area.

A variety can have a wide-broad spectrum of adaptation or be limited to certain areas of production.

Our Work

Field visit

The best way to evaluate and make your choice for the most suitable varieties, is to come and visit our trial blocks at our places or at some of our partners’ ones. You will be able to check the fruits on trees, taste them and make up your mind.

One of our technicians will advise and guide you, giving you all the useful information about the varieties and technical recommendations about rootstocks, pruning, thinning, etc… helping you making the best choice.

Protecting our varieties

Our best varieties are protected in Europe Union with a CPVR (Community plant variety right) certificate issued by the CPVO (Community Plant Variety Office).

Certificates from non-EU countries are applied individually in each country.

They are also registered in several different national catalogues.

Our intellectual property rights are defended by specialized lawyers in every countries where our varieties are distributed and by dedicated organisations such as GESLIVE.

To date, PSB has registered and protected more than 100 varieties of apricots, peaches and nectarines (round or flat shaped).



Do not miss our news

Despite the health crisis that we are struggling with, PSB continues to innovate.
We have planted 30.000 new early and seasonal hybrids on our Murcia´s field.

This year we have developed an
