Genome doubling and chromosome elimination with fragment recombination leading to the formation of Brassica rapa-type plants with genomic alterations in crosses with Orychophragmus violaceus.

Abstract excerpt

In distant hybridization of plants, nonclassical hybrids with unexpected chromosome complements, chromosome elimination, and genetic introgression have been well documented. We obtained intergeneric hybrids between Brassica rapa, B. rapa var. chinensis, and another cruciferous species, Orychophragmus violaceus, following embryo rescue. Hybrids mainly displayed phenotypes of B. rapa, although certain O. violaceus...
