摘要：
The chromosome number of Globodera rostochiensis was determined by investigating: i) bivalent configurations at metaphase I, ii) meiotically reduced cells during oogenesis and iii) somatic mitosis at early embryronic cleavage divisions. A diploid chromosome number of 2n = 18 was found. Chromosome numbers were readily determined in polar bodies using the fluorochrome Hoechst 33258. An improved squashing method enabled observations at early cleavage divisions.
