Abstract
Plant morphology and metaphase I chromosome association of six hybrids betweenC. canephora (subsectionErythrocoffea of sectionEucoffea) andC. liberica (subsectionParacoffea of sectionEucoffea) are described. Between plants, variation in the expression of parental characters was observed and attributed to heterozygosity especially in the liberica parent. Bivalent frequency was high, but comparable to that of earlier reports. Trivalents and quadrivalents, indicating structural hybridity, were observed here for the first time in such hybrids. In spite of their classification in different subsections and apparent hybridization barrier, the two species have considerable chromosomal homology.
