Microsporogenesis of two interspecific allotetraploid somatic hybrids, i.e. 'Hamlin' sweet orange + 'Rough Lemon' (HR) and 'Key' lime + 'Valencia' sweet orange (KV), was examined and compared with their corresponding diploid fusion parents. Meiotic analysis revealed that only 13.2 and 18.0% of the meiocytes exhibited normal tetrad formation in HR and KV somatic hybrid plants, respectively, and irregular chromosome behaviour with univalent or multivalent pairing occurred. Moreover, meiotic… CONTINUE READING
