With 1 figure and 2 tablesAbstract A gene that confers double‐podding in chickpea is considered to be important for breeding higher yielding cultivars. Double‐podded mutants were produced from five desi‐ and four kabuli‐type chickpea genotypes through induced mutations and stabilty was checked up to M 13 generation. Desi‐type produced higher number of mutants as compared with kabuli‐type. The inheritance studies in induced mutants of six genotypes showed that the double‐podded trait was governed by single recessive gene. Different genotypes and their double‐podded mutants were also characterized through sequence‐tagged microsatellite site marker, TA‐80. Allelic variations were found in single‐podded genotypes and eight different alleles were identified, while for double‐poddedness no allelic variants were found in all the analysed mutants. Addition of bases in the double‐podded mutants showed that there might be involvement of transposable elements in the production of double‐podded mutants through mutagens.
