Hybrid Chinese Chestnut
Burbank developed hybrid chestnuts from European, Japanese and Chinese species to increase their resistance to chestnut blight. This tree produces abundant crops of tasty, burr-covered nuts that are prized both by squirrels and humans.
All the items on the Farm were being developed for their resistance to disease as well as tasty and abundant fruit. Please see also #24.
This is a chestnut of the Chinese variety (Castanea mollissima). All the hybrids on the Farm were being developed for their resistance to blight. Chinese Chestnuts are resistant, but when they were introduced into America, they brought with them the fungus, Endothia parasitica which was fatal to our own native Chestnuts, especially Castanea dentata.
The natives, however, produced the sweetest tasting nut, so attempts at hybridization were attempts to combine a blight-resistant tree with a sweet-tasting chestnut.
