Two intergeneric hybrids involving wild species Erucastrum cardaminoides (2 n=18, E(cd) E(cd)) and two crop brassica species, Brassica rapa (2 n=20, AA) and B. nigra (2 n=16, BB), were synthesized through in vitro sequential ovary culture. Morphological, molecular and cytological studies were
Three intergeneric hybrids were produced between a cold-tolerant wild species, Erucastrum abyssinicum and three cultivated species of Brassica, B. juncea, B. carinata and B. oleracea, through ovary culture. The hybrids were characterized by morphology, cytology and DNA analysis. Amphiploidy was
