Timeline of United States discoveries
The Red Delicious is a clone of apple cultigen, now comprising more than 50 cultivars. The Red Delicious apple was discovered in 1875 by Jesse Hiatt on his farm in Peru, Iowa. Believing that the seedling was nothing more than nuisance. After chopping down the tree three times, Hiatt decided to let the tree grow and eventually, it produced an unknown and new harvest of red apples. Hiatt would eventually sell the rights to this type of apple to the Stark Brothers Nurseries and Orchards who renamed it the Red Delicious.
Delicata squash
Indigenous to North and Central America, squash were introduced to early European settlers by Native Americans. "'Delicata' was first introduced by a seedsman in the USA in 1894 (Tapley et al. 1937), but a fruit very much like those of this cultivar was illustrated by Naudin (1856)." (Paris 1989). As a cultivar, is "more or less unique and is not readily classifiable in any one modern group" (Paris 1989). The standard delicata is vinous; however, bush varieties have arisen including 'Bush Delicata', and seed sellers offer varieties with more sweetness as 'Sugar Loaf' and 'Honey Boat'. Delicata squash almost disappeared after the Great Depression, and wasn't widely grown due to its susceptibility to mildew diseases. This was changed in the early 2000s, when a group at Cornell University's Department of Plant Breeding, led by Molly Jahn, bred a non-hybrid open pollinated variety, Cornell's Bush Delicata that was resistant to most known squash diseases, and won the 2002 All-America Selection (AAS), a seed-industry award and is now the primary commercial cultivar.
