Resistance of advanced bread wheat lines to nematodes and Hessian fly - progress update. [p. 161-162]

Resistance to H. avenae. Heterodera avenae-resistance gene Cre2, transferred from Aegilops ventricosa AP-1, has been introduced to advanced bread wheat lines with suitable agronomic traits of interest (quality and/or production) via backcrossing. The resistance gene Cre2 has shown to confer a high level of resistance to the Spanish pathotype Ha71 (Montes et al. 2003). The hexaploid H-93-derived lines from the cross 'T. turgidum subsp. turgidum cv. Rubroatrum, H-1-1/Ae. ventricosa AP-1//T. aestivum subsp. aestivum cv. Almatense, H-10-15' previously described by Delibes et al. (1993), hereafter the selected line H-93-8, was employed as a donors in a hexaploid wheat background. Different commercial wheat cultivars such as Anza, Rinconada, Cajeme, Cartaya, Betres, Marius, and Osona were used as recurrent parents. All crosses were carried out in a greenhouse using standard manual procedures, obtaining two generations/year. Following successive backcrossing (BC4) and selfing, the resulting desirable lines were evaluated for favorable agronomic traits and cereal cyst nematode (CCN) resistance under field conditions in four locations in Spain (Toledo, La Poveda, Gimenells, and Foradada).

Thus, selected lines were consistently tested for CCN resistance, yield and other agronomic traits from 1999 through 2002. Based on 2 years of data at several locations, the cross 'H-93-8/4*Rinconada', under the designation ID-2150, was found to exhibited excellent agronomic characteristics, grain yield, and adequate resistance to CCN under growers conditions (Figure 1). In the autumn of 2003, the line ID-2150 was advanced to be evaluated in the national cultivar testing and registration yield trial at the Spanish Office of Vegetable Variety (OEVV).

Resistance to M. destructor. Mayetiola destructor-resistance gene H27, transferred from Ae. ventricosa, has been introduced to advanced bread wheat lines with suitable agronomic traits of interest via backcrossing. The resistance gene H27 has shown to confer resistance to M. destructor to the Spanish biotype (Martín-Sánchez et al. 2003). The 4D/4Mv wheat/Ae. ventricosa substitution line H-93-33, from the cross 'T. turgidum subsp. turgidum cultivar Rubroatrum, H-1-1/Ae. ventricosa AP-1//T. aestivum subsp. aestivum cultivar Almatense, H-10-15' previously described by Mena et al. (1989, 1993) and Delibes et al. (1993), hereafter H-93-33/H-10-15, were employed as a donors in a hexaploid wheat background. Different commercial wheat varieties such as Anza, Rinconada, Cajeme, Cartaya, Betres, Marius, Adalid, Astral, Recital, Alcotan, and Osona were used as recurrent parents. All crosses were carried out in a greenhouse using standard manual procedures, obtaining two generations/year. Following successive backcrossing (BC4 and BC5) and selfing, the resulting lines were evaluated for favorable agronomic traits and Hessian fly resistance under field conditions in Azuaga (Badajoz) Spain.

Thus, selected lines were consistently tested for Hessian fly resistance, yield and other agronomic traits from 2000 through 2003. Based on 2 years of data at several locations, the cross H-93-33 / H-10-15 / 5* ADALID, under the designation ID-2151 was found to exhibited excellent agronomic characteristics, yield grain and moderate resistance to Hessian fly under growers conditions (Figure 1). In the autumn of 2003, the line ID-2151 was advance to be evaluated in the national cultivar testing and registration yield trial at the Spanish Office of Vegetable Variety (OEVV).
