Gamma ray induced significant phenotypic and metabolite changes in sugarcane variants derived through in vitro mutagenesis.

Sugarcane is an economically important polyploid crop whose genetic complexity and limited fertility poses a challenge for crop improvement programs. Gamma radiation-induced mutagenesis is an alternate approach for generating a diverse array of agronomically useful mutants, accelerating varietal development in a long-duration crop like sugarcane. To develop agronomically useful mutants of a commercial sugarcane genotype Co 99004, gamma ray induced in vitro mutagenesis was carried out.
