Conference paper


A prominent feature of plant tissue cultures is that genetic variations are frequently induced by spontaneous or mutagen-induced mutations or chromosomal abnormalities (Evans et al., 1983; Sunderland, 1977). These callus tissues are genetically chimeric with respect to newly induced characters and therefore could be useful gene sources for effectively isolating variant cells. Such a variation induced in callus tissues has been designated as somaclonal variation and has provided us with a new tool for improving crop plants (Larkin et al., 1981).
