The colors of such a race may
repeat for themselves the peculiarities of the ever-sporting characters.
It often happens that one color is more or less strictly allied to the
doubles, and another to the singles. This sometimes makes it difficult
to keep the various colors true. There are certain sorts, which
invariably exhibit a difference in color between the single and the
double flowers. The sulphur-yellow varieties may be adduced as
illustrative examples, because in them the single flowers always come
white. Hence in saving seed, it is impossible so to select the plant,
that an occasional white does not also appear among the double flowers,
agreeing in this deviation with the general rule of the eversporting
varieties.
I commend all the above instances to those [334] who wish to make
pedigree-cultures. The cooperation of many is needed to bring about any
notable advancement, since the best way to secure isolation is to
restrict one's self to the culture of one strain, so as to avoid the
intermixture of others. So many facts remain doubtful and open to
investigation, that almost any lot of purchased seed may become the
starting point for interesting researches. Among these the
sulphur-yellow varieties should be considered in the first place.
In respect to the great questions of heredity, the stocks offer many
points of interest.
