A tobacco plant that developed from a false broomrape tumor on a primary lateral root of tobacco (cultivar NC 73) was grown to sexual maturity. It was reciprocally crossed to a NC 73 plant grown from seed and the F₁ and F₂ progeny were studied. Both parental plants were also selfed. None of the progeny differed in general morphological characters or chromosomal counts. It was concluded that no obvious genetic or heritable cytoplasmic changes had occurred during the development of the tumor from lateral root tissues or in the subsequent development of shoot and reproductive tissues.
