I think that Randy has a good point here. My experience with iris
breeding was published last year on the back of a postage stamp
but I have had some experience with lily breeding. It has always
seemed to be much simpler to produce a good flower than it is to
breed out disease susceptibility. As a consequence I look very
closely at the stems and foliage of new seedlings and if they show
any botrytis in particular, I trash them before I ever see the bloom.
That eliminates the temptation to coddle a pretty wimp. If it shows
virus symptoms unless it very heavy, I will leave it in place. The
reason for this is to try and find virus tolerance which seems to be
easier to get than total resistance (if such exists.) Another reason
is to make sure that there is lots of virus pressure in the seedling
beds. This will ensure that the seedlings are exposed to disease.
Now while I practice tough love with the yearlings, I do pamper the
new seedlings. I am not convinced that a slow weaker seedling will
necessarily develop into a wimpy plant. I find that some of the good
ones are slow starters and I do not want them to succumb to the
law of the jungle too early in life. There is one exception, and that
involves a close examination of the bulblets when they are
transplanted or planted out to the field. The slightest sign of bulb
rot is sufficient to get that bulb chucked out.
In summary, after trying to give them all a fair start, I become a
predator in the seedling beds. I am sure that I compost many
unseen and beautiful flowers but bringing the healthy ones along is
enough work for me without trying to keep losers alive.
Michael Greenfield expressed some worry that we were going to be
producing plants with good foliage with ugly flowers. The flower is
still the ultimate decider but for me at least, it is the last
characteristic which I evaluate. These are methods which I feel
