Studies on microsporogenesis in genetic male sterile and fertile lines of desi cotton (Gossypium arboreum L.)

Published on

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.
