abstract: Cajanus platycarpus, a distantly related
wild species, was successfully crossed with cultivated
pigeonpea using embryo rescue and tissue
culture techniques. Advance generation lines showed
a range of desirable characters including cytoplasmic
male sterility. A range of pigeonpea cultivars
restored fertility and was maintained by a few lines
including cultivar ICPL 85010. Clasmogamous flowers
were observed in the male sterile lines. In such
flowers anthers did not form di-adlephous bundle.
Cytological analysis revealed that meiosis proceeded
normally till the tetrad stage in those anthers with
pollen grains. After which many of the pollen grains
turned sterile. In the anthers with pollen grains,
dehiscence was not observed, thus creating functional
sterility. In many other anthers, pollen mother cells
(PMCs) were not formed at all, giving rise to
sepalous anthers. In conclusion two mechanisms of
male sterility existed, one was premeiotic, where
PMCs did not form and in the second, although
PMCs gave rise to pollen grains, they were either
partially or totally sterile accompanied by nondehiscence
of anther wall.
