PARTIAL RESULTS ON THE DEGENERATION OF POTATO IN THE MICROZONES FOR SEED POTATO PRODUCTION AT TG. SECUIESC AND APA ROȘIE

Abstract

After the transition of agriculture to market economy the competition has become fierce, so it is very important to increase farm productivity. For a higher production with lower costs you need healthy and productive planting material. Potato producers in Romania and Covasna County have to face for a long time with seed potato degeneration. The team from the Potato Research and Development Station Tg. Secuiesc aims to carry out simultaneous experiments for this purpose. At the Potato Research and Development Station Tg. Secuiesc are followed both the virotic and physiological degeneration of the potato. Since 2011 many experiments have been established in the research fields in Tg. Secuiesc and at the amelioration station Apa Roșie. For each experiments was used the same variety and the same biological category. The results obtained so far show that the indigenous varieties obtained under the climatic conditions in Romania are more resistant to the virotic degeneration than the imported varieties and in many cases yields obtained are similar.
