Physicochemical properties of Four New Genotypes of Guar Seeds (Cyamopsis tetragonoloba L.).
الملخص
The objectives of this work was to study the physicochemical properties of four new guar genotypes (GM5, GM6, GM9 and GM34) collected from the experimental farm of University of Khartoum- Shambat. Proximate composition, Tannin content. One thousand Kernel weight, Hectoliter weight, seed components and hard seeds percentage were carried out for the guar seeds. Result obtained showed that genotypes GM5 and GM34 had significantly (P≤0.05) higher values of 1000-kernel weight compared to the genotypes GM6 and GM9. Genotype GM5 gave the significant (P≤0.05) lowest percentage for hard seeds (11.67%) fallowed by GM34 (17.67%) and GM6 (20.67%) while GM9 gave the highest value (24.33%). Proximate analysis of guar seeds showed that the GM6 had significant (P≤0.05) highest protein content (42.8%) while GM34 gave the lowest value, Genotype GM34 gave significant (P≤0.05) highest value for ash content (5.54%), for carbohydrate (gum content) GM5 gave significant (P≤0.05) highest value (38.58%) fallowed by GM9 and GM34 but the genotype GM6 gave significant (P≤0.05) lowest value of gum content (30.26%). Tannin content was significantly(P≤0.05) lower in GM5 (0.030%).
