Obtained from the «Old Home» x «Farmingdale» cross in the USA. Suited to fertile, permeable, neutral or basic soils. Resistant to bacterial fire blight (Erwinia amylovora) and tolerant of pear decline and the cold. A very important rootstock for the new pear cultivation, suited to medium and high density plantations. Creates slightly less vigour than the BA29 and is compatible with European pear cultivars.
