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]. WebIn order to obtain beneficial viable mutations in C 164 barley [Hordeum sativum Jess), dry dormant seeds were treated with different doses of EMS, gamma rays, 32P and 35S. Twenty two of the 147 viable mutant types scored in the M2 and confirmed in M3 generation, viz., Dwarf, Erectoides, Stiff straw, Very early, Early, Profuse tillering, Synchronous …
