Abstract: The objective of this work was to evaluate the degree of compatibility and agronomic performance in clonal genotypes of canephora coffee plants (Coffea canephora ex Froehner) for cultivation in the state of Rondônia, Brazil. The study was conducted with nine genotypes with three replications of Coffea canephora Arranged in the field- UFRO-60; UFRO-31; UFRO-61; UFRO-25; UFRO-03; UFRO-08; UFRO-21; UFRO-05 and UFRO-138 In adulthood and in two years of harvest (2013/2014 and 2014/2015). We evaluated- productivity, profitability, conversion index fruit cherry/grain benefited, mass of one hundred grains benefited, average diameter of the fruits, number of rosettes per branch, average distance between rosettes and number of fruits per rosette. Additionally, the degree of compatibility between the clones of clonal. The genotypes of Coffea canephora with the best agronomic performances evaluated for the edafoclimatic conditions of the State of Rondônia in this study were UFRO-08, UFRO-25, UFRO-03 and UFRO-138. According to the compatibility tests, the sequence of correct disposition in the field of Coffea canephora among the genotypes studied in this study are- UFRO-138; UFRO-31; UFRO-25; UFRO-08; UFRO-60; UFRO-21; UFRO-61; UFRO-03 and; UFRO-05. Close to 74% of the tests Were and self-pollination tests resulted in low fruiting, evidencing the characteristic of self-incompatibility.
