Old dude gathered bout 3500 subspecies of fruit bearing trees from around the Carpathian basin. Apples, pears, apricots, cherries, peaches, plums, medlars, sour cherries can be found on his orchards, on about 10 hectares. Only from a specific region he preserved 400 pear types - for comparison in the 19th century's France, André Leroy botanist described 700. The oldest subspecies from his orchards are mentioned as early as the 12th century. Probably several hundreds are those types which the last specimen only preserved by him.
Every subspecies were selected for different reasons. Some were better to dehydrate, some gave better pálinka, cider, jam or vinegar, some kept better during winter, some better for diabetes, for stomach aches, or just simply they ripened in different times so fresh fruits were available longer.
He also talks about how the countryside was destroyed. The homesteads and villages. It's all the product of the last 70 years. Bolsheviks deported half the communities, they pushed the peasants to the towns, made workers for industry. Then the rest were forced into collectives, their property was taken, communized. After the regime change the agriculture was dismantled, orchards were cut, pastures were abandoned. Now we eat the filth from Europe. They subsidized the liquidation of the agriculture. Even today new regulations are put into force which put more burden onto those who want to build something instead of destroying. With the projects of the Union culture can't be built, only with freedom.
He tried to apply for a project, financed by the EU. Two bureaucrat came to evaluate if his orchard can get support. They said these trees ain't growing the way they should. He replied it's an [insert obscure subspecies], how should it grow? They haven't even heard about it. Fun.
He also distills wide variety of pálinka.
