Exploitation of the leaf variants in CGMS system derived from A2 cytoplasm in pigeonpea [Cajanus cajan (L.) Millsp.]

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.
