If it could be shown that our domestic varieties manifested a strong tendency to reversion,--that is, to lose their acquired characters, whilst kept under unchanged conditions, and whilst kept in a considerable body, so that free intercrossing
might check, by blending together, any slight deviations of structure, in such case, I grant that we could deduce nothing from domestic varieties in regard to species.
The chestnut seedlings planted at Flight 93 National Memorial are about 94 percent American chestnut, the result of generations of backcrossing and intercrossing
with other hybrid offspring.
Neo-Tuberosum refers to cultivated potato adapted to long-day tuberization and a syndrome of related morphological and physiological traits developed by intercrossing
and selection of short-day adapted potatoes of the Andigenum group.
No less than Leonardo da Vinci mused in his notebook, "The air is full of infinite lines, straight and radiating, intercrossing
and interweaving without ever coinciding one with another; and they represent for every object the true form of their reason (or their explanation).
water channels go throughout the cubic phase and they are separated by MO bilayers, and the diameters are 5-7 nm (5-7).
They have crossed the orange-flesh diploids into the tetraploid population and, beginning in January, will be intercrossing
these tetraploid-diploid hybrids.
In Raleigh, North Carolina, ARS maize geneticist James Holland is working to design a breeding scheme to develop perennial corn, exploring the possibilities of intercrossing
domesticated corn and its perennial relative wild teosinte.
Pmax] was mapping one by one with each injection time and injection quantity, both of them did not exist intercrossing
2] population resulted from intercrossing
