Brazil nut (Bertholletia excelsa) is an emergent canopy species occurring on non-flooded lands (terra firme) in the Amazon basin. Its seeds or nuts, which are collected in the wild and sold on the international market, are an important income source for extractive families living throughout the species range. Seed collection appears to be ecologically sustainable as recent comparative studies demonstrate no negative impact on population structure. Still, technologies for improving production are needed to enhance the economic sustainability of extractive reserves. The objective of this preliminary study, executed in a 465-ha Brazil nut-rich forest within Extractive Reserve Chico Mendes, was to examine factors affecting Brazil nut productivity, focusing on effects of vine loads on adults. Only trees >- 30 cm DBH were considered adults and included in the analysis given that no tree below this cutoff produced fruit. For each tree, DBH was measured, and GPS coordinates and categorical data on vine load, nut production, and crown form and position were collected. Densities and diameter distributions were calculated for the stand. |

A genetic linkage map was constructed using a pseudo-testcross strategy based on a cross between the seedless Vitis vinifera ?Crimson Seedless? and the complex hybrid ?Villard Blanc?, resistant to downy mildew. A total of 315 DNA markers, including 262 AFLP, 48 simple sequence repeats (SSR), 2 SCARs (sequence characterized amplified region) and 3 minisatellite markers were used to generate a map for each parent. For both parents, 19 linkage groups were obtained, covering 1,111.0 cM and 926.0 cM for ?Villard Blanc? and ?Crimson Seedless?, respectively. The position of SSR loci in the obtained maps is consistent with the genomic sequence. Quantitative Trait Loci (QTLs) for seedlessness and resistance to downy mildew were investigated. Two major effect QTLs for downy mildew resistance and seedlessness were mapped on the same region of linkage group 18. These QTLs explain 25.0-55.7% and 54.0-62.,4% of the total variance, respectively. The MIKCC-Type MADS box gene VvAG3, whose orthologue is involved in Arabidopsis carpel and ovule development, and located in the confidence interval of the seedlessness QTL detected on the LG 18, could be considered as a candidate gene to control seed development in grape. Colocalizations were found in the same region, between the position of the Rpv3 locus, which is very rich in TIR-NBS-LRR genes, and the main QTL identified for downy mildew resistance. Our results demonstrate that the same region of LG 18 contains important genetic determinants for seedlessness and downy mildew resistance in grapevine. Moreover, assessing the allelic variation at these agronomically important loci provides a basis for the development of marker-assisted selection for seedlessness and downy mildew simultaneously.
