Field and biochemical evaluation of glyphosate tolerant chickpea (Cicer arietinum L.) mutants developed through induced mutagenesis.

ABSTRACT: Weed control in chickpea (Cicer arietinum L.) is challenging due to narrow genetic base of available germplasm and limited herbicide options. In this view, present research was focused on induced mutagenesis in chickpea for development of herbicide (glyphosate) tolerant mutants and subsequent screening under field conditions. Further, objective was to analyze the defence response and biochemical adjustments in selected glyphosate tolerant chickpea mutants. Initially, 376 chickpea mutants (M₆ populations developed through EMS and gamma rays) were screened for glyphosate tolerance under filed conditions and scored on a 1 to 5 scale based on plant injury related traits. Among tested mutants, 40 were found highly tolerant (score = 5), 32 as tolerant (score = 4) and 20 as highly sens
