ABSTRACT:       This  study  aim  was  to  evaluate  the  agronomic  performance  and  the  postharvest  of  small-sized  Coffea  arabicacultivars and to indicate the best agronomic variable for indirect selecting genotypes for cultivation in high-temperature regions. The  experiment  was  conducted  during  the  2014/15  harvest,  employing  the  randomized  blocks  experimental  design,  with  four  replicates. The treatments consisted of 17 small-sized coffee cultivars. The evaluated attributes were growth, yield and postharvest of the coffee cultivars. Considering their morphological attributes, the cultivars Obatã IAC 1669-20, Catuaí Amarelo IAC 62, Obatã Amarelo IAC 4739 and IPR 99 were superior to the others. As for yield, the cultivars Obatã IAC 1669-20 (51.90 bags ha-1), Catuaí Amarelo IAC 62 (48.05 bags ha-1) and Catuaí Vermelho IAC 99 (47.63 bags ha-1) were superior. In the post-harvest evaluations, the cultivar Tupi IAC 125 (Tupi RN) had the best results. Due to their better agronomic performance, the cultivars Obatã IAC 1669-20 and Catuaí Amarelo IAC 62 are thus recommended for high-temperature regions. Plant height tends to be the best agronomic variable for indirect selecting more adapted cultivars for high-temperature regions.

RESUMO:      Objetivou-se  avaliar  o  desempenho  agronômico  e  a  pós-colheita  de  cultivares  de  café  arábica  de  porte  baixo  e  indicar a melhor variável agronômica para seleção indireta de genótipos para cultivo em regiões de temperaturas elevadas. O experimento foi realizado na safra 2014/15, utilizando-se o delineamento experimental de blocos casualizados, com quatro repetições. Os tratamentos foram constituídos por 17 cultivares de café de porte baixo. Avaliou-se os atributos de crescimento, rendimento e pós colheita das cultivares de café. Considerando os atributos morfológicos, as cultivares Obatã IAC 1669-20, Catuaí Amarelo IAC 62, Obatã Amarelo IAC 4739 e IPR 99 apresentaram-se superior às demais. Quanto à produtividade, as cultivares Obatã IAC 1669-20 (51,90 sc ha-1), Catuaí Amarelo IAC 62 (48,05 sc ha-1) e Catuaí Vermelho IAC 99 (47,63 sc ha-1) foram superiores. Nas avaliações de pós-colheita a cultivar Tupi IAC 125 (Tupi RN) obteve os melhores resultados. Devido ao melhor desempenho agronômico, recomenda-se as cultivares Obatã IAC 1669-20 e Catuaí Amarelo IAC 62 para regiões de temperaturas elevadas. A altura de planta tende a ser a melhor variável agronômica para a seleção indireta de cultivares mais adaptadas em regiões de temperaturas elevadas.
