Stable variability of agronomic traits in the protoclones of two locally adapted indica rice cultivars, IR50 and CO 45, was observed across three generations. Protoplasts regeneration was achieved using seed calli of CO 45 and cell suspension cultures of IR50. Regeneration of proliferated microcalli occurred in MS basal medium in IR50 and in MS + kinetin in CO 45. The Pt1, Pt2, and Pt3 generations of the protoplast-derived plants were evaluated in the field for plant height, tiller number, productive tiller number, panicle length, spikelet fertility, and grain weight per plant. The extent of the stable variability for these traits expressed in the protoclones during the field tests indicates useful genetic diversity and the utility of the protoclones in rice breeding programs.
