Chromosomal associations were studied in three F1 hybrids from the cross Brassica nigra X B. oleracea var. alboglabra. Differences were observed in the extent of chromosome pairing in the three hybrids. Trivalents were observed at a high frequency, indicating allosyndetic pairing and a higher possibility of gene transfer between B and C genomes.
