Mutation induction is a method to increase genetic diversity associated with selection, recombination, or a combination of these approaches in plant breeding. The present research was aimed to compare efficacy of different doses of Gamma rays (150, 200, 250, 300 and 350 Gy and zero dose control) on the sesame morphological traits. Results of cluster analysis of single branch Naz variety to M1 showed that mutations were classified into 8 groups of genotypic and single branch Naz variety exhibited more variation as a result of mutation. The maximum scatter in the measure traits is related to yield per plant, number of capsules and capsule length with coefficients of variation of the 55.29, 47.64 and 39.61 respectively. Thus, these study can introduce a new source of germplasm in breeding programs to classical methods to be evaluated and exploited subsequent generations UR - https://www.ijabbr.com/article_7931.html L1 - https://www.ijabbr.com/article_7931_b944305e09e555a9d52a1a381508339e.pdf ER -
