Trees on Malling-Merton were going out with what was diagnosed as Phytophthora collar rot, and whole blocks on the dwarfing Malling 9 were killed by fire blight.

Dad began his rootstock breeding program inaiming at producing a repertoire of rootstocks that could survive under fire blight and Phytophthora pressure, thrive in our climate so different from that of southeast England where the Malling and Malling-Merton stocks had originatedand provide outstanding orchard performance. He used Robusta 5 and Novole as primary sources of resistance to fire blight and relied on Malling 9 and M.

In the early 70s, pathologist Herb Alwinckle joined the team. Over the years, they produced well overhybrid seeds, emasculating and pollinating perhapsflowers. Our whole family was involved in that hybridization.

To have a longer breeding season, we went as far south as National Arboretum in Washington and north into Quebec. Then outside for testing in the stoolbed. Based on stoolbed behaviour, many hundreds of the seedlings were grafted with test varieties, all virus-free: Northern Spy, Delicious, McIntosh mostly.

Test blocks were set out across the country, from Maine to Washington, with a acre planting at USDA research station at Kearneysville. After Dad and Herb retired, Terence Robinson and Gennaro Fazio have continued evaluating the selections. Very dwarfing, between M. In the nursery, G. Some suckering; nearly no burrknots.

A terrible nursery subject -- fairly difficult to root; many spines. In some test bangkrut main forex subjected to unusually high winds, there has been union breakage of Gala trees on G. We now recommend that most varieties on G.

Already in heavy production in New Zealand. Dwarfing similar to M. Not as productive as G. Precocious sunflower market woodstock very productive.

Requires a permanent support system. Irrigation is very helpful. Resistant to crown rot. Susceptible to nematodes, woolly apple aphid, and fire blight. Because fire blight is becoming so critical throughout our area, we are no longer working with M.

Fedco Trees - Rootstock

In the orchard, the first year or two growth is very slow. Usually free standing, although coursera options trading anchorage can be a problem. Half of standard-sized tree. Moderately resistant to crown rot and to fire blight.

Rootstocks

Suckering can be a problem. We do especially like MM. A great rootstock in the right spot, but a poor choice for some sites. Not precocious -- which is one reason we don't put Northern Spy on it!! Quite prone to burrknots. We like to use MM. In some tests, Bud. In two recent trials, Bud. Not quite so brittle as Malling 9, but staking is still strongly advised. No, the "P" doesn't stand for "Polish" or "Poland", but for the Polish word for rootstock.

Slightly less vigorous than Malling Almost as winter hardy as Antonovka. Anchorage similar to M. Better anchored than M. Burrknots and suckers are rare. Red leaves, red wood, red blossoms, red fruit.

Resistant to fire blight and collar rot. Available sometime in the future as a rootstock. Reimer's strain of fire blight-tolerant seedlings. Reported to enhance fruit size on Asian pears. OHXF 97 is full standard vigor; fire blight resistant. More productive than seedling. Tolerant of soil diseases. Very resistant to fire blight. Tolerant of low temperatures.

Induces early, heavy production. Some reports that fruit size is smaller, but this may be due to excessively heavy fruit set. Fruit ripens 3 to 5 days earlier than on seedling stocks.
