摘要：

Seeds of Medicago truncatula cv. Jemalong line J5 were treated by gamma-rays to create mutations affecting Rhizobium symbiosis. Putative mutants were selected in M(2) and true mutant phenotypes were confirmed in M(3), M(4), M(5) and M(6) generations. Fixed nodulation mutant lines were then screened for their endomycorrhizal characters. Eighteen mutant lines are now available. They consist of 2 non-nodulating and non-mycorrhizal (Nod(-), Myc(-)), 4 low-nodulating and mycorrhizal (Nod(+/-), Myc(+)), 9 nodulating, non-fixing and mycorrhizal (Nod(+)Fix(-), Myc(+)) and 3 supernodulating, nitrate tolerant nodulation and mycorrhizal (Nod(++)Nts, Myc(+)) mutant lines.
