Delta Giant, a triploid (3x = 24) shallot cultivar with two genomes of A. cepa var. ascalonicum [A. ascalonicum] and one of A. fistulosum, was selfed or backcrossed to diploid A. cepa var. ascalonicum. Among 135 progeny analysed, 119 were normal diploids (2n = 16), ten were trisomics and six had more than 17 chromosomes.
