Between 2023-2024 at NIRDPSB Brasov, Romania were performed research to determine the leaf greenness index SPAD and selected potato characteristics, i.e. plant height, yields and tubers starch content on twelve varieties. With SPAD 502 Plus meter (Chlorophyll Meter) were carried out 3 determinations on the leaves of the middle level of 3 plants from each variety taken into the study. Values recorded on 22.06.2023 were between 47.9 and 42.5 units, and those on 18.07.2023 between 47.6 and 42.1 units and the yield varied between 14 t/ha and 45.47 t/ha. Values recorded
on 18.06.2024 were between 49.9 and 41.4 units, and those on 08.07.2024 between 47.0 and 39.9 units and the yield varied between 25.72 t/ha and 7.58 t/ha. The results showed that threshold SPAD values decrease as the growing season progresses for all varieties and the yield is strongly influenced by climatic conditions.
