Note 132 — A DEFENCE OF MENDEL’S PRINCIPLES OF HEREDITY. (continued 2)

One of the peculiarities of most double “sulphur” races is that the singles they throw are white. See Vilmorin, Fleurs de pleine Terre, 1866, p. 354, note. In Wien. Ill. Gartenztg. 1891, p. 74, mention is made of a new race with singles also “sulphur,” cp. Gartenztg. 1884, p. 46. Messrs Haage and Schmidt have kindly written to me that this new race has the alleged property, but that six other yellow races (two distinct colours) throw their singles white.
