Abstract
DRY dormant seeds of Bonus barley have been irradiated with 160-MeV. protons in the scattered beam of the Uppsala synchrocyclotron. The following biological effects were studied: (a) retardation of seedling growth under greenhouse conditions, at 20° C.; (b) germination and (c) survival at maturity under field conditions; (d) sterility (per cent sterile flowers per spike); and (e) mutation frequency estimated from the frequency of spikes giving rise to recessive chlorophyll-aberrant types (cf. Gustafsson1).
