Technical Abstract: Guar [Cyamposis tetragonoloba (L.) Taub.] seed is the source of guar gum that is used as an emulsifier, thickener and stabilizer in a wide range of foods and is part of the dietary fiber in the seed. This study examined the content of total and soluble dietary fiber as well as protein in the seeds of guar. It was found that total, soluble dietary fiber and protein in the seed were significantly variable among guar genotypes. In addition, total dietary fiber content is inversely related to protein content. Differences in total, soluble dietary fiber and protein among guar genotypes were identified. Those genotypes such as PI 263879, PI 212987, PI 263876 were extremely high in total dietary fiber and could be used as fiber supplements or used as parents in a breeding program to enhance such traits.
