Abstract:
Aimed to characterize and evaluate the genetic diversity of Cerrado's Cashew in the 2016 harvest, three studies were conducted. These were conducted in the "ex situ" biological collection by Anacardium humile A. St.-Hil. and at the Laboratory of Genetics and Molecular Biology, both at the Federal University of Goiás - Jataí Regional. For the first study, flowering characteristics of the accessions of the collection were evaluated. The results were submitted to descriptive and multivariate analysis. For the second and third studies were evaluated physical and chemical characteristics of pseudofruits and fruits (from 5 to 15 per access). In the second, the results were submitted to descriptive analysis for each access and Pearson correlation between the measured variables. In the third study, besides the descriptive analysis for the variables, the results were submitted to multivariate analysis. Diversity was observed based on flowering and fruiting attributes, where the UPGMA dendrogram and Tocher Optimization Method were efficient to demonstrate this diversity. The accessions coming from Serranópolis presented high values of flowers number and percentage of flowered accessions. Access 1 presented higher values for fruit size and higher access 3 and pseudofruit vitamin C content, with vitamin C significantly correlating with skin and flesh tone, soluble solids content and fruit length.
