Department of Agriculture Plant Introductions have played an important role in the horticultural, economic, and cultural development of the United States.
For example, Florida's mango industry was founded on early introductions. 'Mulgoba', which had been introduced from India by USDA pomologist H.E. Van Deman in 1889, was the parent of 'Haden', which in turn produced 'Springfels', 'Zill', 'Edward', 'Lippens', and other named varieties.
'Sandersha', introduced from India in 1901, gave rise to 'Brooks', and from this cultivar have come 'Fascell' and 'Kent'.
A recent computer-based study applied techniques of numerical taxonomy to mango cultivars and uncovered a group designated the "Sandersha-Haden complex." Among the ten cultivars placed in this group were 'Irwin', 'Tommy Atkins', 'Keitt', and 'Palmer' (5).
The Saigon type derived from 'Cambodiana', introduced in 1902 by Lathrop and Fairchild, is a parent of 'Florigon' and of station experimental selections MIA 4329 and MIA 13269; seedling populations from these selections and their offspring are being planted for the evaluation and selection of new varieties.
Thus, mango germplasm introduced by USDA obviously entered into the genetic make-up of all commercially important Florida cultivars.
