p. 409: Parador  Chromosome number 27  [Provenance: Guillot]

p. 412: s. All the ploidy levels described an polyploid series 2n = 2x, 3x, 4x and 5x; all but one 'Parador' cv. 2n = 27 chromosomes may be a monosomic, are euploids; in the 'Parador' case, the chromosome number is probably the result of an aneuploid mecanism ( 4x-1).

p. 409: Sonia Rykiel  Chromosome number 35  [Provenance: Guillot]

p. 412: A similar situation may exists with the pentaploid cytotype. This mecanism of the unequal separation, responsible for the fertility of the impair cytotype, has been before observed during the meiose of pentaploid species Rosa canina (2n = 35) by Täckholm ( 1922) and is confirmed by the variety 'Sonia Rykiel' which showed a pentaploid level and a fertility.
