Abstract

Like most Citrus species and varieties, the Puerto Rican chironja has nine pairs of short chromosomes. Although micronuclei are formed sporadically, generally the PMC meiosis is normal, and the pollen looks fertile. The chromosome relations do not help us to decide whether the chironja is a hybrid between orange and grapefruit or not.
