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 early metaphase I. Following the second maturation division, sperm and egg pronuclei fused to form the zygote nucleus. Six females obtained from 200 larval inoculations of soybean seedlings failed to produce embryonated eggs and showed marked retardation in growth. In conclusion, H. glycines has a normal meiotic cycle and reproduces by cross fertilization.
