Genetic variability among guarana (Paullinia cupana var. sorbilis (Mart.) Ducke) provenances to support breeding strategies.

Abstract excerpt

Guarana, an economically valuable species due to its high caffeine content, requires phenotypic evaluation of genetic resources to identify promising accessions. This study assessed variability among 21 guarana genotypes from southern Bahia, Brazil, analyzing 12 fruit/seed traits (e.g., mass, dimensions, water content) and qualitative descriptors (fruit shape/surface). Positive correlations (e.g., fruit mass with...
