| Abstract: | • In order to elucidate the genetic control of resistance toMelampsora larici-populinaleaf rust in hybrid poplars, aPopulus deltoides × P. trichocarpa F1 progeny was analysed for qualitative and quantitative rust resistances.• This progeny was evaluated for three components of quantitative resistance (latent period, uredinia number and uredinia size) to sevenM. larici-populinastrains in controlled conditions, and for one component of field susceptibility (rust colonization on the most infected leaf).• One qualitative resistance locus inherited fromP. deltoides,R1, was localized on the genetic map. It segregates 1 : 1 in theF1 progeny and is effective against four of the studied strains. QTL analysis was performed separately onR1 andr1 genotype subsets. An additional detection was conducted on the entireF1 progeny for the three strains able to overcomeR1 and for MAX2. A total of nine QTLs were detected. Two had large, broad-spectrum effects. One (RUS) is inherited from theP. trichocarpaparent; the other is inherited fromP. deltoides andcolocalized withR1. Seven QTLs had only limited and specific effects. Significant interaction effects were detected mainly between the two major QTLs.• Implications of these results for durable resistance breeding strategies, and possible benefits from thePopulusgenome sequence, are discussed.New Phytologist(2005)doi: 10.1111/j.1469-8137.2005.01424.x© New Phytologist(2005) [ABSTRACT FROM AUTHOR] |
