Five growth regulators were evaluated for their gametocidal properties on four genotypes of pigeonpea. Among the treatments, 1.0-1.5% Maleic hydrazide (MH) and 0.25% Naphthalene acetic acid (NAA) induced sterility, Genotype P 856 was the most responsive while 89-7-16 was the least responsive to different treatments. Spray just before the flower bud initiation was found to be the most vulnerable stage of crop growth for inducing high pollen sterility but phytotoxic effects were observed with ethrel at higher concentrations.
