Burnham and his team focused on introducing the blight-resistance properties from the Chinese chestnut
The Chinese chestnuts
kind of look more like apple trees.
(Castanea mollissma Blume) is an economically important cultivated species being low in fat and good eating quality with generally medium in size (Wang et al.
There were eighteen empty shells at the base of the taller tree, and the squirrels who were still ransacking the nearby Chinese chestnut
trees had long since closed the inventory on this fellow.
Dunstan saw an opportunity to save the American chestnut by grafting it to a Chinese chestnut
trees have naturally good form, so not much pruning is needed to get the growth described here.
Castanea mollissima, the Chinese chestnut
, closely resembles its European counterpart, and is used in much the same way, while the Japanese chestnut, Castanea crenata, bears a larger, starchier nut that is more often served intact than ground into flour or meal.
The blight seems to have originated in Asia, and some trees of the Chinese chestnut
species don't even develop cankers when they encounter the fungus.
And in recent decades a program to hybridize American chestnuts by back-crossing them with the blight-resistant Chinese chestnut
has finally found a degree of success.
based foundation, said since 1983, the group has crossed the American chestnut with the Chinese chestnut
, which is resistant to the blight.
He understood that on his slow march toward his heavenly reward, he would spend as many years as possible growing and backcrossing the American with the Chinese chestnut
The site is also a working demonstration of edible landscape and permaculture design, featuring everything from heritage red raspberries and heirloom apples you can pick yourself to their own creation: a blend of the American chestnut and Chinese chestnut
The recently identified 40-year-old pure Chinese chestnut
trees started to drop their nuts yesterday.
The Chinese chestnut
and the blight evolved together in Asia, so the Chinese chestnut
is blight-resistant, and can contain the spread of the fungus.
Upper grades study forest ecology, perform DNA experiments, and study the genetics of backcrossing Chinese chestnut
hybrids to surviving native chestnuts, aiming for a tree that incorporates the desirable characteristics of the native with just enough Chinese to resist blight.
