Abstract

A comparative histological study of GAKA·423 male sterile and fertile anthers of desi cotton (Gossypium arboreum L.) revealed shriveling of microspores leading to deformed microspores without the complete development of pollen wall. The Genetically Male Sterile (GMS) anther sacs were completely appressed towards center enclosing the deformed microspores, which appeared as thick black undifferentiated band. The tapetum persisted during premeiotic and meiotic stages and disintegrated after release of microspores.
