摘要: Mutants with changes of seed protein content in rice were obtained by ethyleneimine (EI) treatment three levels concentration. In M2 generation mutation frequency and nurnber high mutants increased the increasing EI Agronomic characteristics some also observed M4 generation. The characters most them improved or at least sirnilar to those original variety. These facts seem suggest possibility breeding new varieties grain utilization induced mutants.
