Phenotypic Variability in the Induction of Alpha Acids in Hops (Humulus lupulus L.) in Brazil

Hops (Humulus lupulus L.) is a key ingredient in beer, with great significance for the Brazilian industry. The economically viable production of hops Brazil depends on genetic variability available to be used selection and development high-as performance photo-neutral cultivars their interaction environment. objective this research was evaluate phenotypic alpha-effective character relation environmental variation different regions. Alpha-acids tests were performed through American Society Brewing Chemists (ASBC-HOPS 6. B-Conductometric titration methodology). Phenotypic assessment showed that 30% occurred among clones, while 47% attributed components cultivation. repeatability coefficient (t) below 0.25, demonstrating between genotype environment inflicted alpha-acid levels. Results contents depending growing According results, clones 9 (8.22%), 26 (12.95%) 27 (9.94%) added highest levels alpha-acids. Therefore, there improvement culture its effects must evaluated each microclimate
