Abstract: OOGENESIS AND MODE OF REPRODUCTION IN THE SOYBEAN CYST NEMATODE, HETERODERA GLYCINES1) BY A. C. TRIANTAPHYLLOU and HEDWIG HIRSCHMANN Departments of Genetics and Plant Pathology, North Carolina State College, Raleigh, North Carolina, U.S.A. Oögenesis and mode of reproduction were studied in four populations of the soybean cyst nematode, Heterodera glycines. Oögonial divisions occurred before and during the fourth molt. Maturation of oöcytes proceeded only in inseminated females and was normal, consisting of two meiotic divisions and the formation of two polar nuclei. Nine bivalents were present at metaphase I in all populations. Sperm entered the oöcytes at late prophase or
