Differences between Cajanus cajan (L.) Millspaugh and C. cajanifolius (Haines) van der Maesen, the progenitor species of pigeonpea uri icon


  • A study was undertaken to know the difference/diversity between pigeonpea and its closely related wildspecies C. cajanifolius by studying their morphology, crossability, cytology of the hybrid between the two,and molecular studies. Studies revealed that there are at least 5?6 traits that separate the two species such asflower morphology, pod color and morphology, pod constriction, seed color and strophiole, 100 seed weightthat separate C. cajan from C. cajanifolius . Molecular studies revealed that a genetic dissimilarity index valueranging from 0.81 to 0.94 exists between the two species
