| Abstract: | This study was undertaken to explore the possibilities of using in vitro techniques for selection of sheath rot-resistant soma clones of rice cv Co43. Oryza nivara and O. longistaminata possessing sheath rot-resistance were included in the study, with a view to comparing the reaction of the susceptible somaclones of O. Sativa cv Co43 to a crude toxin preparation from culture filtrate of the pathogenic fungus, Sarocladium oryzae. A few somaclones of Co43, selecfed on the crude toxin preparation, regenerated into plantlets and their reaction to the toxin was reconfirmed up to R1 generation. |
