TWO NEW POTATO VARIETIES AND THEIR GROWTH PARAMETERS, DISEASES RESISTANCE, ADAPTABILITY AND YIELD

Rezumat

In this study, two new potato varieties, namely Amural and Postavaru, along with standard variety Brasovia were evaluated for their adaptability, agronomic traits and other parameters including tuber yield. Varieties Amural and Brasovia showed a higher level of tolerance to tuber diseases. Regarding tuber yield, Amural variety, achieve significantly higher yield of 22.86 t/ha. Regarding the quality parameters, the dry matter content varied between 21.21 % (Brasovia) and 26.28 % (Amural), starch content between 13.50 % (Brasovia) and 15.92 % (Postavaru) and the culinary quality of tubers were from classes B (Brasovia and Amural) and B/C (Postavaru), showing the suitability for multiple uses. Our findings argue for the strategic selection of high-performance potato varieties as a key lever for increasing yield and adaptability to specific climatic conditions.
