The productivity analysis of five leading potato varieties in the agroecological conditions of a mountainous region in Montenegro

Abstract

An analysis of genetic productivity potential of five leading varieties in Montenegro (Kennebec, Agria, Aladdin, Tresor and Riviera) was conducted during 2010 and 2011 in the municipalities of Žabljak region, on mountainous black soil at 1,500 meters of altitude. The highest number of tubers was found in a parcel planted with Tresor and Aladdin-8.5, while the lowest number of tubers was found in Kennebec-6.8 tubers per plant. Comparing to other tested varieties, Kennebec had a significantly lower number of tubers. On average, Kennebec and Tresor had the largest tubers (96 and 91 g), and differences found were statistically very significant. The biggest tuber yield was measured in Tresor-32.5 t/ha, while the lowest tuber yield was in Agria and Riviera (24.0 and 25.2 t/ha). Tresor had significantly higher tuber production comparing to other varieties.
