Web1 de mar. de 2003 · A high proportion of spontaneous DH plants is particularly beneficial in breeding, as there is no need to use colchicine to double haploid chromosomes. In barley, DH plants can be induced through either IMC or AC. By using the IMC method, spontaneous DH frequencies ranged from 59 to 85% [3], [6], [16], [17], [18].
