Abstract

Dry seed samples of the upland rice variety IRAT109 were treated with γray irradiation. Mixed seed bulk was collected from M2 plants. Mutated individuals were collected at seedling, tillering and heading stages from M3 population under dry cultivation and traditional cultivation for several seasons. The mutant population had 260 lines with stablyinherited mutations identified in M5 generation. A proportion of the mutants were described including mutants in leaves, culms, panicles, grains, and drought tolerancerelated traits. The segregation ratios of F2 population were observed for a couple of mutants. In addtion, the problems on screening mutations for drought tolerance and the utility of this mutant population were discussed.

Key words： upland rice; irradiation induced mutation; mutants; morphological characteristics; drought tolerance
