“…Our field experiment conducted in Poland revealed that spelt wheat plants, grown at two levels of protection, with root and stem base necrosis symptoms occurred at a higher percentage than in the case of spelt wheat grown in western Canada [24], but at a lower percentage than common wheat 'Tonacja' grown under the above-mentioned conditions with complex protection [15]. Species of the genus Fusarium proved to be the cause of damage to spelt wheat plants grown at the two levels of protection.…”

“…Fusarium avenaceum was the dominant species on ears of wheat crops in Saskatchewan, Canada, in 2011 in the dark brown soil zone [42]. The occurrence of the species F. avenaceum and F. culmorum on the roots and stem bases of spelt wheat in the minimal chemical protection treatments and in all study years confirms the competitive abilities of these fungi, enabling them to live in the soil and infect plant roots [15,21,25]. Fernandez et al [43] indicated a differential effect of the input level on the most common Fusarium spp.…”

“…Regardless of the protection level applied, F. culmorum was the species that was most frequently isolated from infected roots and stems of spelt wheat. This species has a high contribution to various root and stem rot diseases, including in spelt wheat [6,15,21,[25][26][27][28]. The highest number of isolates of this species was isolated both from roots and stem bases of spelt wheat in the case of both protection levels in 2007, which could be attributed to the weather conditions favorable for the growth of this fungus, i.e., the high temperature and humidity from May to July [15].…”

Investigations were carried out in 2007–2009 on the plots of the Felin Experimental Station belonging to the University of Life Sciences in Lublin, Poland. The studies comprised two breeding lines of spelt wheat (Triticum aestivum ssp. spelta L. Thell.) – STH 3 and STH 715. Two levels of chemical protection were applied in the cultivation with minimal and complex protection. Infection of winter spelt wheat roots and stem bases was recorded in each growing season at hard dough stage (87 in Zadok’s scale). After 3 years of the study, the mean values of disease indexes for the analyzed spelt wheat lines in the experimental treatment with minimal protection were 28.53 and 40.30 respectively for STH 3 and STH 715. In the experimental combination with complex protection, after 3 years of the study the mean values of disease indexes ranged from 25.96 (STH 3) to 26.90 (STH 715). The mycological analysis showed that Fusarium spp., especially F. culmorum, caused root rot and necrosis of stem bases of spelt wheat in the experimental combination with minimal and complex protection. Moreover, Fusarium avenaceum and Bipolaris sorokiniana caused root rot and necrosis of stem bases of spelt wheat. Investigation carried out in a growth chamber on susceptibility of seedlings of three lines of spelt wheat (LO 2/09/n/2, LO 5/09/13/3, LO 5/09/5/4) to infection with Fusarium graminearum No. 8 and F. graminearum No. 45 showed that the genotypes did not differ in their susceptibility. All of them were susceptible, as indicated by high values of the disease indexes. No interaction was found between genotypes and strains of the fungus. This indicates the differential pathogenicity of Fusarium graminearum species.

A b s t r a c tThe present study was carried out in the years 2010-2012 in the fields of the Strzelce Plant Breeding Company Ltd., belonging to the Plant Breeding and Acclimatization Institute in Radzików, and it included 39 oat genotypes. At the six-week seedling stage, the percentage of plants with root and leaf sheath necrosis symptoms was evaluated. In 2010 the percentage of seedlings with disease symptoms ranged from 6.5% to 25%, in 2011 it ranged from 17% to 34.5%, whereas in 2012 from 10% to 25%. In 2010 the disease index ranged from 1.4 to 5.7, in 2011 from 4.5 to 8.8, while in 2012 it was between 2.0 and 5.4.Mycological analysis showed that large numbers of Fusarium spp. colonies were obtained both from the roots and leaf sheaths. Isolates of these fungi accounted for 63.48% of the total fungi isolated from seedlings. Seedlings grown under the conditions of central Poland were damaged by the species F. culmorum, F. avenaceum, and F. solani. The investigation of the susceptibility of 15 oat genotypes to infection with two Fusarium graminearum strains -Tz 56 and Tk 235 -was carried out under growth chamber conditions at a temperature of 22-23 o C and relative air humidity of 85%. The F. graminearum strain Tz 56 proved to be the most pathogenic to seedlings of the breeding lines STH 0.9403 and POB 1316/08, for which the disease index was 80.5 and 75.5, respectively. The lowest pathogenicity of the a.m. strain was recorded in the case of the genotype DC 1832/05, for which the disease index was 26.5. The F. graminearum strain Tk 235 proved to be the most pathogenic to the genotypes STH 0.9403 and STH 0.9423, for which the disease index was 70.5 and 70.0, respectively, whereas this strain was least pathogenic to the breeding line DC 2112/05, in the case of which the disease index was 25.5.
