Abstract

The conventional potato breeding process has led toapproach this crop plant also under the implementation of modern biotechnology methods.Due to its capacity for in vitro regeneration, the potato has a rich history in tissue culture experiments.Micropropagation techniques are the safest, most elaborate and fastest way to provide planting material for a seed potato crop andalso for consumption.Laboratory monitoring, control in a protected space (insect-proof spaces), regarding the growth and development status of plantlets determines the assurance of phytosanitary quality according to the established standard.Biometric observations were made on the biological material taken into study, for three Romanian potato varieties - Asinaria, Darilena and Foresta, regarding the average height of the plant, the average number of shoots and leaves, and by using the SPAD device, measurements were made on the chlorophyll content of potato leaves at the time of transplanting the vitroplants and after the acclimatization period.
