A population consisting of 184 recombinant inbred lines (RILs) from a cross between durum wheat (Triticum durum Desf.) cvs. “Meridiano” (highly resistant) and “Claudio” (moderately susceptible) was grown during the 2006-07 season in a field with natural inoculum sources of SBCMV near Bologna, and evaluated for SBCMV-symptom severity expression and ELISA absorbance in extracts from leaves. Comparative analysis of symptom severity and ELISA absorbance values in time showed the presence of a sizeable temporal change in the relative degree of resistance of the lines in terms of symptom expression and virus concentration in leaves, responsible for marked changes in resistance ranking order among lines.

Abstract
A population consisting of 184 recombinant inbred lines (RILs) from a cross between durum wheat (Triticum durum Desf.) cvs. “Meridiano” (highly resistant) and “Claudio” (moderately susceptible) was grown during the 2006-07 season in a field with natural inoculum sources of SBCMV near Bologna, and evaluated for SBCMV-symptom severity expression and ELISA absorbance in extracts from leaves. Comparative analysis of symptom severity and ELISA absorbance values in time showed the presence of a sizeable temporal change in the relative degree of resistance of the lines in terms of symptom expression and virus concentration in leaves, responsible for marked changes in resistance ranking order among lines.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
