Fusarium head blight incidence and mycotoxin accumulation in three durum wheat cultivars in relation to sowing date and density

In 2009, a set of 35 cultivars of durum wheat (Triticum turgidum L. subsp. durum (Desf.) Husn.) of Italian origin was screened for fusarium head blight (FHB) susceptibility at CIMMYT (Mexico) and in the 2019–20 cropping season, 16 of these cultivars, which had been included in the Italian National Plant Variety Register, were tested again in southern and northern Italy. Wheat cultivars were artificially inoculated during anthesis with a conidial suspension of Fusarium graminearum sensu lato using a standard spray inoculation method. Inoculum was a mixture of mono-conidial isolates sourced in the same areas where the trials were performed. Isolates had been characterized on the basis of morphological characteristics and by DNA PCR amplification using a specific primer set and then selected for their virulence and ability to produce mycotoxins. The susceptibility to FHB was rated on the basis of the disease severity, disease incidence and FHB index. Almost all of the tested cultivars were susceptible or very susceptible to FHB with the only exception of “Duprì”, “Tiziana” and “Dylan” which proved to be moderately susceptible. The susceptibility to FHB was inversely correlated with the plant height and flowering biology, the tall and the late heading cultivars being less susceptible.

Artificial Inoculations

Fusarium head blight (FHB), caused by Fusarium spp., has become one of the most destructive diseases in the world’s wheat growing areas , especially in the humid and semihumid regions (Paillard et al. 2004, Mesterhazy 1978, Stack & Mullen 1985; Kiecana 1987; Kiecana et al. 1988). Six winter wheat cultivars, recently released and widely grown in Trasylvania, have been evaluated for FHB resistance during 2006. The evaluation was made by means of artificial inoculations with Fusarium graminearum and assesment of symptom intensity by computing AUDPC index (Area Under Developmental Progress Curve). Based on these data, two cultivars (Dumbrava and Turda 195) were considered as resistant, two cultivars (Ardeal and Arieşan) as medium resistant and other two cultivars (Fundulea 4 and GK Öthalom) as susceptible to FHB. The reaction to FHB of the six tested cultivars, based on the postharvest indices, showed significant differences among these cultivars as far as the yield elements and the total grain yield were considered. Actually, in the resistant cultivars, both the total grain yield and some of the yield elements (spike wight, grain weght/spike and 1000 kernel weigt) were significantly less affected by FHB than in medium resistant and susceptible cultivars.
