The fertile C.G. White halfbreds that burst on the scene in the late 40s and early 50s are widely considered the foundation stock of our modern arilbreds. Like most folklore, this story has grown from a kernel of truth – but it also includes its share of myth. 

Truth:  the availability of this fertile family revolutionized the world of arilbred hybridizing.  When White's creations were distributed, suddenly anyone could intercross them and get fully fertile halfbreds in the first generation.

Myth:  there were no fertile arilbreds before White's time.  There were indeed earlier amphidiploids, but they had been too few and far between to constitute a viable gene pool.  White accumulated the needed stock and, by making thousands of crosses, produced the requisite gene pool  

The following list includes some of C.G. White's own creations and some produced by others using his foundation stock.  All had been reported fertile in ASI Newsletters and Yearbooks of the period, subsequently counted as 44- or 45-chromosome amphidiploidlike hybrids, and defined as OGBs by the 1976 committee even when pedigrees were not available.

Some have contributed a major part of the modern gene pool and can indeed be considered the progenitors of today's fertile family of halfbreds. Others had few registered descendants and thus contributed little or nothing to the modern gene pool. 

The links are to lists are from a book I compiled in the late 1970s, for early hybridizing experiments.  They were based on the 1976 ASI Checklist thus should include all applicable earlier introductions.  I updated the book sporadically, as I found newer cultivars of interest, so some descendant lists do include later introductions but most identify recent lines rather than present an exhaustive list of cultivars.

In each list, descendants that are also members of this same fertile family are shown with this light green background.

Ahmed Aga (Clarence G. White, 1953). Blend of violet, lavender, buff, and chamois. Notes: Parentage unknown., but counted as a 44-chromosome amphidiploid. Limited number of registered offspring, all fully fertile but little used.

Arjuna Aga (Clarence G. White, 1953). Blend of lilac, old gold, and olive-ochre. Notes: Parentage unknown, but counted as a 44-chromosome amphidiploid. Minor contributor to the modern gene pool, as most of its registered offspring are infertile.

Asoka of Nepal (Clarence G. White by Lena Lothrop, R. 1950). Lavender, olive-ochre, purple blend. Counted as a 44-chromosome amphidiploid; from an analysis of White's records, Tom Wilkes reported the pedigree as Joppa Parrot X B-46. A significant contributor to the modern gene pool, with registered, fertile offspring from a number of hybridizers.

Bali Aga (Clarence G. White, 1952). Purple, cream-buff, and dahlia-carmine blend. Parentage unknown, but counted as a 44-chromosome. Significant contributor to the modern gene pool, with registered, fertile offspring from a number of hybridizers.

Beisan Aga (Clarence G. White, 1954). S port wine veined darker; F buff heavily veined dark purple-black. Black signal. Parentage unknown, but counted as a 45-chromosome amphidiploid. A major contributor to the modern gene pool, with registered, fertile offspring from a number of hybridizers.

Black Joppa (Clarence G. White, 1954). S aster heavily veined prune-purple; F straw veined Spanish raisin. Craig, 1954. Notes: Parentage unknown, but counted as a 44-chromosome amphidiploid. Made no contribution to the modern gene pool, as it had only one registered, fertile offspring and that in turn had no registered offspring..

Citrine (Clarence G. White selected by Eckels, R. 1953). Citrine yellow and deeper yellow, veined. Parentage unknown, but reportedly fertile and counted as a 45-chromosome amphidiploid. No registered offspring.

Imam Adib (Clarence G. White, 1956). Blended bi-color of pale lilac veined light lobelia; F old gold dusted gold; beard old gold. Parentage unknown, but counted as a 44-chromosome amphidiploid. No contribution to the modern gene pool, as GATES AJAR was its only registered offspring and it in turn had no registered offspring. 

Imam Ahmid (Clarence G. White, 1956). Blend of buffs and purples; beard dark tawny olive. Parentage unknown, but counted as a 44-chromosome amphidiploid. One of the most important of C.G. Whit'es breeders, a major contributor to the modern gene pool through the introductions of a number of hybridizers.

Imam Jaban  (Clarence G. White, 1956). S oyster white, cream lines; F primuline yellow edged lighter; beard straw yellow. Parentage unknown, but counted as a 44-chromosome amphidiploid. Minor contributor to the modern gene pool, through the introductions of Henry Danielson.

Imam Salah (Clarence G. White, 1956). Blend of grey, violet, mulberry and brown; coral-red signal surrounded brown. Parentage unknown, but counted as a 44-chromosome amphidiploid. Major contributor to the modern gene pool, though the introductions of a number of hybridizers.

Jabal Kerak (Clarence G. White, 1955). White and pale lemon yellow; primuline yellow beard; dahlia purple signal patch. Parentage unknown, but counted as a 44-chromosome amphidiploid. Minor contributor to the modern gene pool, through its fertile offspring introduced by Danielson.

Jallah Ad-din (Clarence G. White, 1955). Cinnamon drab, olive, and yellow blend. Joppa Parrot X B-46, counted as a 44-chromosome amphidiploid. 

Jallah Effendi (Clarence G. White, 1952). Yellow-green, red and mahogany blend, purple splashed. Parentage unknown, but counted as a 44-chromosome amphidiploid. Major contributor to the modern gene pool, with fertile offspring registered by a number of different hybridizers.

Joppa Parrot (Clarence G. White, 1948). S light mauve, streaked mulberry; F bronzy gold, patterned cinnamon-red and yellow, and streaked mulberry black; golden-bronze beard. Parentage unknown, but counted as a 44-chromosome amphidiploid. Analysis of White's records suggests that Joppa Parrot as the most likely progenitor of the original set of registered amphidiploidlike hybrids, even though exact pedigrees are not available. As it was introduced at a time when there were few other fertile arilbreds available, most of its registered offspring were 1/4 aril or less.

Kalifa Baltis (Clarence G. White, 1955). Blend of olive buff and bordeaux splashed lavender and purple. Parentage unknown, but counted as a 44-chromosome Major contributions to the modern gene pool, used by a number of hybridizers.

Kalifa Gulnare (Clarence G. White, 1955). S pale orchid-lavender; F same, heavily overlaid apricot-buff. Parentage unknown, but counted as a 44-chromosome amphidiploid. The most widely used of all of C.G. White's fertile halfbreds, with more registered descendants than any other of White's cultivars – many attributable to its offspring, Esther the Queen.

Kalifa Hirfa (Clarence G. White, 1955). Violet toned blend flecked amethyst; beard dahlia-purple; speckled signal. Parentage unknown, but counted as a 44-chromosome amphidiploid. Major contributor to the modern gene pool, used heavily by both Flanagan and Rich.

Kalifa Kabul (Clarence G. White, 1956). Blend of chartreuse, Indian buff, and absinthe yellow splashed greyed purple. Parentage unknown, but counted as a 44-chromosome. Relatively minor contribution to the modern gene pool, with only two registered, fertile offspring and one other registered, fertile descendants.

Tatai Pasha (Clarence G. White, 1955). S primuline yellow; F stippled and penciled russet, shading to primuline yellow; liver-brown signal. Parentage unknown, but counted as a 44-chromosome amphidiploid. Relatively minor contribution to the modern gene pool, with only three registered, fertile offspring and three other registered, fertile descendants.

Vinaya of Shankara (White-Lothrop, 1951).. Grey, yellow, and brown blend. Craig, 1951. Parentage unknown, but counted as a 44-chromosome amphidiploid. No registered offspring. 

Yussuf AB (Clarence G. White, R. 1942).  No information on introduction found in AIS Checklists. Parentage unknown, but counted as a 44-chromosome amphidiploid. It apparently has not contributed to the modern gene pool because it had only one registered offspring, JADE, which not only had no registered offspring but was disenrolled when the quantum system was adopted.
