Abstract:

Regenerated calli of two landrace (Lawi and Siam) and three modern rice varieties (MR219, MR232 and UKMRC9) were exposed 2 to 7 Gy of gamma rays to determine their effects on callus growth and plant regeneration capability. Both callus growth and regeneration capacity were found to be decreased with increasing levels of exposure to gamma rays. Plant regeneration capacity was found more sensitive to gamma rays than callus growth. However, local landrace varieties showed comparatively less sensitive to gamma radiation of these characters as compared to modern varieties. The doses 5 and 4 Gy of gamma radiation were found to be the 50% inhibition dose for callus growth and plant regeneration in Lawi and Siam, respectively; whereas, the 50% inhibition dose for MR219, MR232 and UKMRC9 was 3 Gy. These results indicate that sensitivity of gamma radiation on rice callus depend on genotype of a genus.
