 In: Joint FAO/IAEA Div. of Isotope and Radiation Applications of Atomic Energy for Food and Agricultural Development, Vienna (Austria). Semi-dwarf cereal mutants and their use in cross-breeding. Proceedings of a research co-ordination meeting organized by the Joint FAO/IAEA Division of Isotope and Radiation Applications of Atomic Energy for Food and Agricultural Development and held in Vienna, 2-6 March 1981. Jul 1982. p. 65-7283-919808Summary: The durum wheat breeding programme aims at improving the local cold tolerant varieties for lodging resistance, higher yield and good grain quality. The Bulgarian durum wheat cv. 233 has been submitted to mutagenic treatment of gametophytes (1,2,3,4 krad, 60Co gamma-rays), seed (10 krad, 60Co gamma-rays; 1 krad, fast neutrons; EMS, 1,5 for 20 hrs at 20 deg. and both gametophytes and seeds (2 krad + 10 krad, gamma-rays); 2 krad gamma-rays + 1 krad, fast neutron; 2 krad -gamma rays + EMS, 1.5). 2264 M1 plants were harvested and it each plant the spike of the main culm was kept separate from those produced on the later tillers.
