Abstract

Ten promising varieties of forage sorghum were evaluated for stability of performance for plent height, stem girth, tillers/plant, leaves/plant, lest langth in 5 environments in two cuts at Anand (Gujarat) during 1980-81. Genotypes and evironments were highly signili cant in both cuts for all the characters studied. Characters like clant height tillers/plant. leaves/plant and leaf breadth were unstable in all the varieties studied, However, varieties like M. P. Chari in First cut for stem girth and leal length and 15 3211 in second cut for stem girth showed average stability. Genotype IS 3201 showed the maximum plant height, stem girth and leaf length and wes generally stable, SSG 59-3 possessed higher tillers and the highest leaves/plant. Stability parameters showed association between X and b for plant height.. and Sd for leaves/plant and X and b for leaf breadth, All three parameters were significantly associated for tillers/plant.
