Summary: Molecular markers (RAPD, AFLP and microsatellites) were used to generate a linkage map and to identify QTLs associated to witches broom (Crinipellis perniciosa) resistance in cacao (Theobroma cacao), using 82 individuals of an F2 population derived from the clones ICS-1 (susceptible) and Scavina-6 (resistant). Fifteen evaluations of the number of brooms have been carried out in six years (1997-2000). In order to increase the precision and accuracy in the measures of resistance, each F2 plant was cloned in three replications in randomized block desing with single-tree plots and evaluated over 2 years. Three hundred and forty-two markers were obtained, being 33 microsatellites, 77 AFLPs and 323 RAPDs. The distribution of the number of brooms in the F2 population was skewed to resistance, suggesting the involvement of major genes controlling resistance and the repeatability estimated for resistance was 44%. A strong piutative QTL was detected as being related to witches' broom resistance. Associated to this QTL, the microsatellite mTcCIR35 explained 35.5% of the phenotypic variation in resistance. This marker is being used for marker-assisted selection in Scavina-6 progenies, including those selected in private plantations, as an auxiliary tool to the phenotypic selection. |

The introduction of N2-fixing species in fast-growing eucalypt plantations is a strategy where eucalypt growth is limited by N availability. The objective of this chapter is to gather some results obtained in the last decade regarding above- and belowground mixed forests of Eucalyptus and Acacia mangium growth in Brazil and to give insights into the main drivers influencing their development, as well as soil and climatic conditions, silvicultural management, and species interactions. Elevated temperature and humidity are ideal for the aboveground biomass production. Nitrogen fixed by A. mangium contributes to the superior performance of the mixed-stand rotation when compared to eucalypt monoculture, avoiding the use of mineral N. Arrangements and spacing (design of planting) between trees and interactions as competition and facilitation processes have strong influence on the development. Canopy stratification may increase light interception and make them more productive than monocultures. They may also exploit soil site resources more completely through the development of fine root systems. Mixed plantations can also result in long-term sustainability, such as increasing soil C sequestration and soil N concentrations, favoring the dynamics of nutrient cycling, and protecting against pests and diseases, as well as diversifying of timber and non-timber forest products. |
