HYBRIDIZING: Age of Flower Used
It can be in bloom for only one day or when fully opened as long as the stigmatic fluid is sticky. ODA76-22; flowers not more than' two days old are best, before the stigmatic surface becomes contaminated. 0DA76(4)-26

HYBRIDIZING: Barriers Within a Genus
They exist, but the chromosome numbers are important; chances are increased of achieving fine crosses if tetraploids are used, they lessen with triploids or aneuploids. ODA76(4)-25

HYBRIDIZING: Between Two Bigeneric Species
Breeding can proceed in seven ways without the usual male or female position in crossing; example: Miltonia and Oncidium: MxO, OxM, MOxO, MOxM, OxMO, MxMO, MOxMO. 0DA76(4)-25

HYBRIDIZING: Early or Late Flowers
Flowers coming out after half the flowering season is over are more likely to take than the early ones. ODA76(4)-24

HYBRIDIZING: Information on Breeding
The time of year in which to do a cross varies with circumstances but mainly whether the two flowers are available or whether the pollen has been properly stored; consideration should be directed to too many factors for summarizing; claim: pollination is best done during the second and fourth quarters of the moon when tides are rising higher and no leaves fall from the trees; sounds like the way the Druids did it.

HYBRIDIZING: Reciprocal Crosses
These can make a difference because in yellow and orange colored flowers, spotting and some other traits, desirable or not, are transmitted through other parts of the cell besides the genes, oddly enough, so are particularly inherited from the mother plant. OIE87Jy-14

HYBRIDIZING: Response to Flowers in Crossing
There is great variation in the same spray; some set only on one side of the peduncle; some only set on the last flower, or on the first flower of the main peduncle, or on the third flowering on a single spray. ODA76(4)-24

HYBRIDIZING: Sib Crossing
Sib crossing of new clones of species with old clones of the same plant may develop fine qualities as an improvement over both parents; more sib crossing to achieve superior forms advised. ODA76(4)-26

HYBRIDIZING: Species
Species kept too long in captivity become poor breeders. ODA76(4)-26

HYBRIDS: Aspects
The female (pod, or capsule, parent) is always the first name in writing the cross, which is the. opposite for animals; reciprocal crosses make a difference in certain traits such as yellow and orange coloring, and spotting is transmitted through other elements in the cell not the genes, so are particularly inherited from the mother.

HYBRIDS: Primary Crosses
In their characteristics they tend to be midway between the two parents; it is in the subsequent generations that "improvements" begin to show up in a breeding programme'. OR87-187

HYBRIDS: Registration At the Grex Level
A proposal for publication of the name of the actual cultivar parents for the identification of exact strains (repeats) of particular hybrids, because there is such variation in the quality and characteristics in hybridizing; refer to OR87-338
