Abstract

Through in vitro culture studies, suitable explant and combination of phytohormones
were standardized for maximum frequency of callus induction and regeneration in
fodder sorghum variety CO (FS) 29. The in vitro derived plants were forwarded to
the field as SC2 generation (somaclones) by selfing the SC1 generation for the evaluation
of somaclonal variations in quantitative characters. The somaclone (SC2) lines
recorded extensive variations for quantitative traits viz., plant height, days to 50%
flowering, number of tillers plant-1, number of leaves plant-1, leaf length, leaf breadth,
panicle length, grain yield plant-1 and green fodder yield plant-1. Somaclone lines were
critically analysed for genetic parameters and scope for improvement of green fodder
yield plant-1 is discussed.
