“…The presence of tolerance to Zymoseptoria tritici could be only established among our cultivars when the linear regression between GLAD -GY was analyzed. These findings are supported by several studies which have confirmed that measurements of canopy size, and in particular, the effect of disease on GLAI, correlate more closely to yield loss than estimates of the percentage of disease severity alone (Lim and Gaunt, 1981;Waggoner and Berger, 1987;Whelan and Gaunt, 1990;Bryson et al, 1995;Parker et al, 2004;Foulkes et al, 2006). In our study the model including Table 2 Mean squares (MS) from the combined analysis of variance for green leaf area index (GLAI), non-green leaf area index (NGLAI) at GS 39, 60, 82, green leaf area duration (GLAD) and non green leaf area duration (NGLAD) on ten wheat cultivars under three inoculation treatments with Zymoseptoria tritici in two years.…”

“…For example, the beta zone in rice leaves infected with Pyricularia oryzae (a hemibiotroph) was significantly larger than that in wheat leaves infected with powdery mildew (an obligate biotroph) ( Bastiaans, 1991 ). Consequently, the disruption of photosynthesis in the AGR may reduce plant functionality and negatively impacting crop yield ( Whelan and Gaunt, 1990 ; Serrago, 2009 ).…”

“…Sin embargo, este enfoque no proporciona información sobre el tamaño del canopeo del cultivo, que puede variar entre años y sitios, y por lo tanto, diferir en el área verde funcional remanente. Dado que, la duración del área foliar verde (DAFV) está más correlacionada con las pérdidas de rendimiento que la severidad o el ABCPE por sí sola (Waggoner & Berger 1987;Whelan & Gaunt 1990;Bryson et al 1997;Foulkes et al 2006), es que autores como y sugieren que dicha variable es la más se ajusta en los modelos de cuantificación de tolerancia. En el capítulo 2 se abordará con mayor detalle estos temas.…”
