A sexual hybrid between Brassica juncea and Diplotaxis muralis
An intergeneric sexual hybrid, B. juncea X D. muraus, was produced. Morphological and cytological studies confirmed the hybrid nature of the plant. Pollen stainability was 52% and the hybrid plant was partially fertile. The PMCs showed 34 to 39 chromosomes. Mean chromosome associations were 5.9 I, 9.9 II (mostly ring), 1.6 III and 1.8 IV per meiocyte.
