Summary

The interspecific (C. arabica × tetraploid C. canephora) F1 hybrid showed a low but highly variable fertility. An almost complete restoration to normal fertility was observed in individual trees of BC1 and BC2 generations with C. arabica as recurrent parent. From a comparison of various tests of fertility, it was found that pollen viability is a satisfactory measure of fertility.
