Next to variety-testing and hybridizing it is the great source of the steady progression of agricultural crops. From a practical standpoint the method is clear and as perfect as might be expected, but this is not the side of the problem with which we are concerned here.
Phaius it is often spelt Phajus is so closely allied with Calanthe that for hybridizing purposes at least there is no distinction. Dominy raised Ph. irroratus from Ph. grandifolius × Cal. vestita; Seden made the same cross, but, using the variety Cal. v. rubro-occulata, he obtained Ph. purpureus. The success is more interesting because one parent is evergreen, the other, Calanthe, deciduous.
Those who are originating new kinds of potatoes still use seed from the balls, either taking their chances by natural variation or, by hybridizing the blossoms, increasing the chances for variation from which desirable varieties are taken by selection, to be afterward multiplied by growth from the tubers. Seed-Ends of Potatoes. Is it bad practice to plant the seed-ends of potatoes?
What may be accomplished by breeding and hybridizing is beyond imagination. Every seedling of the pomological apples is a new variety. Some of these seedlings are so good that they are named and introduced into cultivation. They are grafted on other stocks, and become part of the great inheritance of desirable apples.
Again he adds: "I believe from observations communicated to me by Mr. Hewitt, who has had great experience in hybridizing pheasants and fowls, that the early death of the embryo is a very frequent cause of sterility in first crosses. Mr. Salter has recently given the results of an examination of about 500 eggs produced from various crosses between three species of Gallus and their hybrids.
Veitch made this cross about the same time, but the seedlings of the former flowered in 1889, of the latter, in 1891. Here we see an illustration of the advantage which French horticulturists enjoy, even so far north as Paris; a clear sky and abundant sunshine made a difference of more than twelve months. When Italians begin hybridizing, we shall see marvels and Greeks and Egyptians!
Some years before he had conceived the idea of hybridizing buffalo with black Galloway cattle; and with the characteristic determination and energy of the man, he at once set about finding a suitable range. This was difficult, and took years of searching. At last the wild north rim of the Grand Canyon, a section unknown except to a few Indians and mustang hunters, was settled upon.
But it seems likely to me that when hybridizing becomes a common pursuit with those who grow orchids and the time approaches fast a very strange revolution may follow. It will appear, as I think, that the enormous list of pure species even genera recognized at this date may be thinned in a surprising fashion.
Moreover it may easily be effected by any one who cares for experimental studies, but has not the means required for cultures on a larger scale. And lastly, there are a number of questions about heredity, periodicity, dependency on nourishment and other life conditions, and even about hybridizing, which may be answered by this new method.
