Research on the Identification of Potato Genotypes Suitable for Cultivation under the Conditions of the New Climatic Changes

There is presented a comparative study of potato varieties of Austrian origin in terms of production and productivity elements as well as the main indicators of the photosynthesis process under the pedoclimatic conditions in the Dejului area. The research carried out in 2017 highlights the identification some potato varieties suitable suitable for the specific climatic conditions of hot and dry summers as well and their relation with some physiological parameters that can characterize the adaptability to modified climatic conditions. The climatic changes observed in the last decades, characterized by moderate temperatures and high rainfall in May and June and frequently in the first part of July, favor the early and semi-early varieties and which can assimilate a reasonable and quality production (30-40 t/ha) without being exposed to the extreme climatic conditions of high temperatures and drought from the second part of July or from August and September, which can have serious consequences on removal from vegetative rest, of sprouting in the nestor accented dehydration.
