“…The controls T23 Obatã IAC1669-20 1, T24 Acauã and T25 Tupi showed higher beverage quality scores and lower stability. The cultivar Obatã IAC 1669-20 of late maturation cycle and the cultivar Acauã resistant to water deficit showed higher beverage quality compared to cultivar Tupi, usually recommended for cultivation in regions fertile soils and mild climate (Carvalho, 2008;Fazuoli et al, 2018). The control T22 Catucaí Amarelo 2SL of high productivity in regions of high temperatures had higher beverage quality grade in the Alta Floresta D´Oeste -RO (A1) environment (Carvalho et al, 2012;Souza et al, 2019).…”

“…Acauã is a cultivar with high resistance to water deficit and good beverage quality (Carvalho, 2008), Catucaí Amarelo 2SL stands out for good resistance to rust, high yield and good beverage quality (Carvalho et al, 2012). Obatã IAC 1669-20 is a cultivar resistant to rust that has late maturity and good beverage quality (Fazuoli et al, 2018), and the Tupi cultivar has short height, resistance to rust, and medium beverage quality, being recommended for growing in regions of fertile soil and mild climate (Carvalho, 2008).…”
