Eucalypts are susceptible to a wide range of diseases. One of the most important diseases that affectEucalyptusplantations worldwide is caused by the rust fungus Puccinia psidii. Here, we provide evidence on the complex genetic control of rust resistance in Eucalyptusinter-specific hybrids, by nalyzing a number of full-sib families that display different patterns of segregation for rust resistance. These families are totally unrelated to those previ-ously used in other inheritance studies of rust resistance. By using a full genome scan with 114 genetic markers (microsatellites and expressed sequence tag derived microsatellites) we also cor-roborated the existence and segregation of a resis-tance locus, explaining 11.5% of the phenotypic variation, on linkage group 3, corresponding to Ppr1. This find represents an additional validation of this locus in totally unrelated pedigree. We have also detected significant additive9additive digenic interactions with LOD [10.0 on several linkage groups. The additive and epistatic QTLs identified explain between 29.8 and 44.8% of the phenotypic variability for rust resistance. The recognition that both additive and non-additive genetic variation (epistasis) are important contributors to rust resis-tance in eucalypts reveals the complexity of this host-pathogen interaction and helps explain the success that breeding has achieved by selecting rust-resistant clones, where all the additive and non-additive effects are readily captured. The positioning of epistatic QTLs also provides starting points to look for the underlying genes or genomic regions controlling this phenotype on the upcoming E. grandisgenome sequence.

The aim of this work was to organic fertilization, liming, and levels of soil conditioner composed by humic and fulvic acids on the characteristics and nutrition of "iceberg" lettuce. The experimental design was completely randomized in a 5x3x2 factorial scheme, in which 5 levels of soil conditioner ( 0, 20, 40, 100, 200 L ha-1), 3 fertilizers (chicken manure, organic compost and mineral), and liming (with or without). Lettuce shoot fresh and dry weight, shoot commercial fresh and dry weight, height, circumference, and number of leaves were evaluated. Lettuce grown with chicken manure rendered the greater circumference and higher shoot fresh commercial weight, which are the most important lettuce characteristics affection consumer purchase decisions. The soil conditioner did not influence on plant growth, except height and dry shoot weight on a very small scale. |
