p. 409: La France  Chromosome number 21  [Provenance: Guillot] 

p. 412: The triploid level is generally considered to generate seed sterility; however for the roses systems, that is falsed since the first known triploid cv. 'La France' is quite fertile.... our hybridization programme demonstrated the successful behaviours of those triploid genotypes; when they are used in the female way, they led to a fructification and germination percentage around 20%. This fertility is probably the results of a high performing regulation process working during the chromosome migration in the meiosis.

p. 409: Laure Charton Chromosome number 14  [Provenance: Guillot]

p. 412: About the hybridization program, the crossing 2x X 2x with 4 females and 6 males led to a mean value of the fructification percentage 11%. The particular case of the 'Laure Charton' cv. was point about this pollen which was able according to the female partner to give a fructification success with a range of 0% ('Robin Hood' and 'New Dawn') to 23% ('Ferdinand de Lesseps'); the pollen seemed inefficient everytime its partner is belonging to the polyantha group.
