USPP36111P2 - Apple tree named ‘J. Lincoln’ - Google Patents

Abstract

‘J. Lincoln’ is a new apple tree distinguished by its resistance to the disease fire blight, and its flavorful fruit, which is well-suited for hard cider production.

Description

Latin name: The Latin name of the genus and species of the plant claimed is Malus domestica.

Variety denomination: Variety denomination: ‘J. Lincoln’.

BACKGROUND OF THE VARIETY

‘J. Lincoln’ is a unique and distinct variety that grew as a chance seedling along the edge of the forest on private family property in Cornish, Maine. The parentage of the ‘J. Lincoln’ variety is unknown. There is an abandoned orchard nearby where the ‘J. Lincoln’ variety was discovered, but none of the apples from the abandoned orchard resemble the ‘J. Lincoln’ variety. Red Astrachan and Duchess of Oldenburg are old varieties that used to be planted in the abandoned orchard, but these varieties lack the tannins that fruit from the claimed ‘J. Lincoln’ variety possesses. The ‘J. Lincoln’ apple tree produces fruit that does not resemble fruit from either Red Astrachan or Duchess of Oldenburg varieties. Additionally, fruit from the claimed ‘J. Lincoln’ variety has tannins that fruit from the Red Astrachan and Duchess of Oldenburg varieties lack. The ‘J. Lincoln’ apple tree variety was discovered in 2015. ‘J. Lincoln’ was first asexually propagated by grafting in Cornish, Maine. Since grafting, ‘J. Lincoln’ has been observed to remain true to type through asexual propagation. The ‘J. Lincoln’ variety has, over a period of several years, consistently exhibited excellent tree growth habit, precocity, superior fruit quality, and disease resistance.

BRIEF DESCRIPTION OF THE VARIETY

The ‘J. Lincoln’ apple tree is distinguished by its resistance to the disease fire blight. Fire blight is a contagious disease affecting apples and some other types of fruiting trees. Fire blight is caused by the bacterium Erwinia amylovora. The disease is a serious concern to apple producers, as under some conditions fire blight can destroy an entire orchard in a single growing season. The ‘J. Lincoln’ variety exhibits resistance to fire blight, making it more preferable than other non-resistant varieties. Additionally, the fruit of the ‘J. Lincoln’ apple tree variety is quite flavorful and well-suited to the production of hard cider. The productivity, storability, and pollination requirements of the ‘J. Lincoln’ variety are unknown.

Apples from the variety ‘J. Lincoln’ are also distinguished by attractive flushes of deep red striping overlay on a lighter red-orange base color with caramel colored russet that distends from the stem. ‘J. Lincoln’ has a growth habit that produces many lateral branches with lots of fruiting spurs. ‘J. Lincoln’ naturally has a semi-dwarfing growth habit.
