Influence of selected Polish and American rootstocks on the growth and yield of 'Golden Delicious Reinders' apple trees

Abstract

This study was conducted in the period 2010-2015 to assess the influence of rootstocks on the growth and fruiting of apple trees of the 'Golden Delicious Reinders' cultivar. The experiment was conducted in an experimental orchard in Dąbrowice, Poland. The experimental material consisted of the Polish rootstocks P 66, P 67, P 68 and P 16, and the following American rootstocks of the Cornell Geneva series resistant to fire blight: CG.11, CG.41, CG.013 and CG.202. The rootstocks M.9T337, M.26, P 14 and P 60 were used as the control combination. The best-yielding trees were those from the CG.11 rootstock, while those from P 14 and P 67 were the lowest-yielding. Trees from the latter rootstocks grew most vigorously and had the lowest productivity index.
