Abstract

Preliminary observations of microsporogenesis of a genetic-cytoplasmic male sterile line showed that the development of sporogenous tissue and the progression into PMCs was normal. The tapetum showed signs of disintegration, suggesting that the development of the PMCs had progressed; the PMC developed into tetrads. Signs of meiotic failure appeared later when cytoplasm was seen to separate from the wall of the newly formed pollen grain; vacuolation then occurred and the pollen eventually became clear and unstained. Meiotic failure of the genetic-cytoplasmic male-sterile line occurred at a later stage than that reported for genetic male-sterile sources.
