The effect of year and genotype on productivity and quality of potato

The study presents results of a three-year experiment variability different potato varieties in Montenegro: early maturity (Riviera), medium (Almera, Aladin and Bounty) late (Agria, Margarita, Kennebec Desiree). research was conducted during 2015, 2016 2017, acid, brown soil three climatic locations: Nedakusi (556 m a.s.l.), Sutivan (680 a.s.l.) Orahovica (900 a.s.l.). Field experiments were set up using standard methodology random block design repetitions. analysis variance suggest that number tubers per plant, mean tuber weight, yield small tubers, marketable total yields significantly fluctuating depending on genotype (G), year (Y) the location (L). In addition to individual influences factors, their interactions also pronounced (G x Y, G L, Y L). period average, highest recorded (31.41 t ha-1), followed by (21.35 while lowest average (17.36 ha-1) Orahovica. As expected, percentage dry matter found Agria - 25.46%, then Desiree 25.33%, with 25.13%, variety Almera 20.82%. variety, Desiree, Riviera. Obtained show over observed locations formed high plant (Aladin) (Desiree Agria) give satisfactory stable yields.
