Abstract
The effect of gamma-ray radiation treatment on wheat x triticale cross ability and the frequency of F1 embryo necrosis and regeneration was s tudied. The triticale pollen was irradiated at 1kR, 2kR, and 4kR using a Co-60 source. The number of seed set significantly decreased with i ncrease in radiation dosage. The 1kR and 2kR dose treatment resulted i n significant reduction of the frequency of embryo necrosis wich is a limiting factor of embryo regeneration in vitro. No embryo was obtaine d with 4kR radiation.
