In the present study, cytoplasmic male sterility derived from A2 cytoplasm of pigeonpea was combined with four leaf type agronomic backgrounds by using backcrossing programme These four leaf shapes were recessive in the expression against lanceolatus leaf shape. These naked eye polymorphic (NEP) markers will be useful for maintaining purity of hybrid seeds if coupled with cytoplasmic male sterility hence present investigation was conducted. In flower structure, keel petals were found open in Obcordifoliate leaf parent similar trait was transferred into respective CMS line, this trait will help in enhancing hybrid seed production and reduces its cost. Different hybrid combinations were made using new leaf type CMS and hybrids made by using obcordifoliate leaf showed highest seed yield over standard checks. Restorer lines used in the present study effectively restored the fertility new CMS lines. Performance of leaf type CMS in different hybrid combinations showed wide scope for utilizing these naked eye polymorphic (NEP) markers in future pigeonpea hybrid breeding program that will certainly help to maintain the genetic purity of CMS lines and quality of hybrid seed.
