Abstract:
1. Genetic analysis of male sterility induced in the progeny of fertile graft components grafted with cytoplasmic male-sterile components of Petunia showed induction of two types of male sterility: one exhibiting inheritance, as did the original trait in the male-sterile graft component; the other exhibiting monogenic recessive Mendelian male sterility. 2. Both gametes have to be produced on symbionts grafted with malesterile components to realise induction of cytoplasmic male sterility in the progeny of the fertile graft component. The induction of genic male sterility was found with either one of the gametes produced on a fertile symbiont grafted with a male-sterile component. 3. Latency of the induction phenomenon was found in a cutting of a graft symbiont giving genic male-sterile progeny. In contrast to this, induction was lost in a cutting of a graft symbiont giving cytoplasmic male-sterile progeny. 4. In the "induction phase" (graft generation) the genic type of male sterility, if induced, prevails. On the other hand, no restoring effect on the cytoplasmic trait by the monogenic sterility factor has been found in later generations. 5. The genetical evidence indicates asexual transmission of a cytoplasmic factor in Petunia, chromosomal integration of a cytoplasmic factor in a higher plant, and mutual exclusive cytoplasmic and chromosomal genetic alternatives for male sterility in Petunia. © 1971 The Genetical Society of Great Britain.
