Scab Response of Selected Winter Wheat Cultivars after Inoculation with Fusarium avenaceum (Fr.) Sacc.

Inoculation experiments with 09 winter wheat cultivars were performed in two di}erent regions of Poland\ which have di}erent climates\ located at Cerekwica "Central! west# and Sitaniec "South!east part of Poland#\ in the seasons of 0884 and 0885\ and Fusarium avenaceum iso! late KF 192 "ATCC 53340# "producing moniliformin# was used in inoculation of winter wheat heads[ The per! centage of scabby kernels was changeable during the experiment\ although no interaction environment cul! tivar was observed[ Yield traits con_rm that the climatic conditions in Sitaniec are favourable for higher scab inci! dence\ and indicate that cultivar Aleta was "at both locations# the most resistant to the disease[ Reduction of all yield traits for all the cultivars\ at two locations\ during two vegetative seasons\ indicates that cvs Aleta\ Almari and Begra were of the lowest susceptibility to scabwhereas Rosa and Parada were the most susceptible to the disease[ Accumulation of moniliformin in kernels on average in Sitaniec was 1[17 mg:g during 0884 and 9[30 mg:g in 0885\ and in Cerekwica it was 1[01 and 0[66 mg:g in 0884 and 0885\ respectively[ The results of chemical analysis con_rm low susceptibility of cultivar Aleta to scab[
