ABSTRACT.
Apple scab caused by Venturia inaequalis is the most important disease of apple in Uruguay. Under conventional management an average of 14?16 fungicide sprays are used each season to control this disease. In this work, the elimination of fungicide sprays for apple scab control after mid-December was evaluated during two seasons in three commercial apple orchards planted with cultivars of Red Delicious, the main apple produced in Uruguay. This finding was based on the ontogenic resistance which implies that the susceptibility to apple scab of leaves and fruits decreases with the ageing of the tissues. Increments of scabbed leaves happened during the summer and fall in all orchards evaluated, but this increase happened in both treatments, with or without fungicide applications during the summer. Instead, none of the orchards evaluated showed increases of apple scab lesions on fruit after December 15th. This finding suggests that it is feasible to reduce up to 30% of fungicide sprays to control apple scab in apple fruit that are harvested from January (like cultivars of Gala) to March (like cultivars of Red Delicious) in Uruguay.

ABSTRACT:Genomic regions infl uencing resistance to powdery mildew [Blumeria graminis (DC.) E.O.Speer f. sp. hordei Ém. Marchal] were detected in a doubled haploid (DH) barley (Hordeum vulgare L.) population derived from a cross between the breeding line ND24260 and cultivar Flagship when evaluated across four fi eld environments in Australia and Uruguay. Signifi cant quantitative trait loci (QTL) for resistance to B. graminis were detected on six of the seven chromosomes (1H,
2H, 3H, 4H, 5H, and 7H). A QTL with large effect donated by ND24260 mapped to the short arm of chromosome 1H (1HS) conferring near immunity to B. graminis in Australia but was ineffective in Uruguay. Three QTL donated by Flagship contributed partial resistance to B. graminis and were detected in at least two environments. These QTL were mapped to chromosomes 3H, 4H,and 5H (5HS) accounting for up to 18.6, 3.4, and 8.8% phenotypic variation, respectively. The 5HS
QTL contributed partial resistance to B. graminis in all fi eld environments in both Australia and Uruguay and aligned with the genomic region of Rph20, a gene conferring adult plant resistance (APR) to leaf rust (Puccinia hordei Otth), which is found in some cultivars having ?Vada? or ?Emir? in their parentage. Selection for favorable marker haplotypes within the 3H, 4H, and 5H QTL regions can be performed even in the presence of single (major) gene resistance. Pyramiding such QTL
may provide an effective and potentially durable form of resistance to B. graminis. MenosABSTRACT:Genomic regions infl uencing resistance to powdery mildew [Blumeria graminis (DC.)
