Description The in vitro pollen germination study was carried out by using pollens of six genotypes which included two popular hybrids, two female and two male parents viz, DCH-177, ICH-66, DPC-9, SKP-84, DCS-9 and ICS-164 to know the competitiveness of interspersed staminate flowers (ISF). The standardized medium containing 15% sucrose, 0.01% H3BO3, 0.3% Ca(NO3).4H2O, 0.0214% Mg (SO4) 7H2O and 0.01% KNO3 were used in the study. The results revealed that highest % of pollen germination observed with ISF pollens of female parents (DPC- 9: 57.35% and SKP- 84: 44.51%) in both the hybrids compared to their respective male parents (DCS-9: 47.24% and ICS-164: 27.27%). It indicated the importance of rouging of ISFs in order to maintain the high genetic purity in castor hybrid and parental seed production.
