The aim of this study was to determine whether the weeds accompanying potato crops can be a source of Alternaria spp. causing Alternaria leaf blight and to determine the genetic similarities of Alternaria alternata isolates infecting selected weeds: Chenopodium album, Cirsium arvense and tested potato cultivar. Three-year field experiment was conducted on the potato cultivar ‘Vineta N’. The isolates were classified into different species on the basis of macro- and microscopic features. In each year of the study, A. alternata dominated among the isolated fungi colonizing the leaves of potato plants and the selected weeds. The genetic similarities of A. alternata isolates was determined by the RAPD-PCR method. Tested genetic forms of A. alternata were closely related; only small differences in the pattern of the separated amplification products was evidenced. The dominance of A. alternata on the weeds accompanying potato crops suggests that if weed infestation is extensive, the pathogen is very likely to spread and its population to increase.

Cut Seed

Shoots of the early-maturing potato (Solatium tuberosum L.) cultivar Jemseg often do not emerge uniformly when cut seed pieces are planted in cold soil. Under controlled temperatures of 10, 15 and 20 °C, shoots from whole tubers and basal portions of Jemseg tubers emerged later than those from apical portions of seed tubers. The delayed emergence of the basal portion was most pronounced at low temperatures and ranged from 5 to 17 d. Emergence from basal vs. apical portions of Conestoga was delayed by 10 d at 10 °C and by 4 d at 15 °C, only when seed tubers with a single dominant apical sprout were used. There was no delay at 20 °C. The variable time to emergence of shoots in the field can be explained by delayed emergence from basal buds on cut seed pieces.Key words: Potato, cultivars, emergence, bud position, temperature, seed tuber
