Abstract
Reducing the number of interspersed staminate flowers (ISF) in female line is an important breeding objectivein castor. An experiment was carried out to investigate the effect of ethrel spray on the level of ISF induction inpistilate linesin castor. Male line (SKI-215) and pistillate line (SKP-84) were grown in 4:1 ratio. Ethrel wassprayedat 0.1 per cent in pistillate line. Ethrel treated pistillate line exhibited significantly less number of the ISF in primary spikes.In addition, ethrelspray lead to reduced length of primaryspike, increased spike compactness, early induction of flowering, early spike development, stunted stigma growth and reduced plant canopy.
