Bud-sports show the same degree of inheritance as seed-sports. Sexual
and asexual variability therefore seem to be one and the same process in
this instance. But the deeper meaning of this and other special features
of our genealogical tree are still awaiting further investigation. It
seems that much important evidence might [321] come from an extension of
this line of work. Perhaps it might even throw some light on the
intimate nature of the bud-variations of ever-sporting varieties in
general. Sectional variations remain to be tested as to the degree of
inheritance exhibited, and the different occurrences as to the breadth
of the streaks require similar treatment.
In ordinary horticultural practice it is desirable to give some
guarantee as to what may be expected to come from the seeds of brightly
striped flowers. Neither the pure red type, nor the nearly yellow
racemes are the object of the culture, as both of them may be had pure
from their, own separate varieties. In order to insure proper striping,
both extremes are usually rejected and should be rooted out as soon as
the flowering period begins. Similarly the broad-striped ones should be
rejected, as they give a too large amount of uniform red flowers.
Clearly, but not broadly striped individuals always yield the most
reliable seed.
