Evaluation of potato varieties under different agroecological conditions in Serbia

Abstract

The main goal of long term evaluation of potato varieties under different agroecological conditions in Serbia was to find out performance, adaptability and yield stability of new introduced potato varieties. Field trials were placed in Zemun and Guča. Mean monthly temperatures and precipitation were observed during vegetation season. The total yield of tubers and yield of marketable potatoes including the all healthy and non-damaged tubers heavier than 70 g were examined. Significantly higher total and marketable tubers yield was appointed at the location Zemun. Early and medium early varieties Adora, Cleopatra and Latona have performed well regarding total and marketable potato yield, whereas medium early to medium late varieties were very sensitive to high temperatures and drought. .

Glavni zadatak višegodišnjih ispitivanja sortimenta krompira u agroekološkim uslovima Srbije je bio da se ustanovi ponašanje, prilagodljivost i stabilnost prinosa introdukovanih sorti krompira. Ogledi su postavljeni na području Zemuna i Guče. Praćene su srednje mesečne temperature i količina padavina tokom vegetacionog perioda krompira. Merenje ukupan prinos i prinos tržišnih krtola, koji je podrazumevao sve zdrave i neoštećene krtole teže od 70 g. Ustanovljenje signifikantno viši prosečan ukupan i prinos tržišnih krtola na lokalitetu Zemun. V pogledu visine ukupnog prinosa i prinosa tržišnih krtola izdvajaju se rane do srednje rane sorte Adora, Cleopatra i Latona, dok su srednje slasne sorte vrlo podložne negativnim efektima visokih temperatura i zemljišne suše. .
