Self compatible varieties do not require other varieties to pollinate, which allows setting up monovarietal orchards. Before planting my first orchard, I tried to choose the right ones. I found much advertisement on new varieties in specialized webpages. From the 1970s on, research institutes in France and Spain have obtained varieties which bloom late and are self-compatible, which are supposed to be the key features to stand the severe conditions at bloom in central Spain. What they do not say much is that this kind of varieties already existed in Puglia, South East Italy.
Filippo Cea is a traditional Italian variety. It is named after its breeder, who was an almond producer. It was already grown in Italy during the 1880s. It seems to be resistant to fungal diseases and to be very productive. The only negative comment that I have read is that it produces many double kernels. It seems to be very appreciated because of its flavour and fat content for producing traditional pastries. There is an Italian association founded by Filippo Cea descendants that promotes it (http://assfamigliafilippocea.altervista.org/).
Lauranne was obtained by the French institute of agricultural research (INRA). It was a cross-breed selection of Tuono (another self-compatible Italian variety) and Ferragnes. Its Plant Breeder Right ended in 2007, surrendered by its holder. This variety has been successfully grown in Spain for years. According to the data provided by a Valencia based centre of agricultural research, this variety blooms late, is suitable for dry land and the quality of the fruit is good. It is resilient to fungal diseases. Lauranne has been used during the last decades by Spanish institutes to cross-breed new varieties.
According to their respective chilling hours and heat requirements, and taking into account the climatic data of my region, their respective blossom times lag 14 and 21 days that of Marcona, the hoary example of Spanish variety. If Marcona bloomed in February, 14, Filippo Cea would bloom in March 1 and Lauranne in March, 8. In 2017 and 2018 Lauranne was at full bloom by late March.
I was able to find nursery trees of Lauranne for the orchard that I set up in 2013. I have observed its resistance to fungal diseases. Young trees are easy to prune and train. I bought nursery trees of Filippo Cea for 2016 planting. Filippo trees are even easier to train because they grow vigorous upright branches.
In 2017 Lauranne trees, which were 5 years old, yielded 100 grams of kernel per tree, with a 33% kernel/ruit ratio and 20% of double kernels. In 2018 those same trees produced an average of 600 grams, with a 31% kernel/fruit ratio and no double kernels.
