Meiosis in anthers and mitosis in somatic cells were studied in reciprocal F-1 hybrids of the accession VIR320, which belonged to wild Pisum sativum ssp. elatius (Bieb.) Schmal., and the laboratory line Sprint-1. When VIR320 was used as a maternal form, the hybrids displayed nuclear-cytoplasmic conflict, which caused chlorophyll defects and meiotic abnormalities. One or two chromosomes lagged in the equatorial region during chromosome segregation to the poles, distorting cytokinesis and yielding abnormal microspores. Chlorophyll defects were not observed, and meiotic abnormalities were far less frequent in reciprocal hybrids and in the case of an abnormal paternal inheritance of plastids from Sprint-1. Mitosis lacked overt abnormalities in all of the hybrids.
