Also, mutagenic treatment had stimulatory effect on plant height at 200Gy gamma-rays in both genotypes and at 0.01 percent concentration of Colchicine. Results also revealed that, two types of chlorophyll mutants were observed in flowering stages. Also results indicated that significant differences were recorded among the mutants for all characters studied in YG0016 and YG40054 mutant groups. Results obtained of composition analysis of fenugreek mutants revealed of existing variability among fenugreek mutants for chemical composition.<\/span><\/p>\n Key Words<\/strong>:\u00a0 Gama-rays, Colchicine, Hydroxyl-Amin , Breeding, mutation, Fenugreek.<\/span><\/p>\n Full paper in Arabic: pdf<\/a><\/strong><\/span><\/p>","protected":false},"excerpt":{"rendered":" Naji M.
