The influence of rootstock on the yield of standard apple seedlings in theb Chui valley of Kyrgyzstan

On the basis of KNAU educational farm, studies were carried out to identify the effect of clonal rootstocks on the yield of standard apple seedlings. The objects of study were clonal rootstocks of apple trees MM106, M26, M9, ARM18, JETSU5. Apple varieties Golden Delicious, Kandil Sinap, Rashida, Renet Burchardt were tested as a scion. Kyrgyz winter. Kyrgyz winter variety, the is author Garev E.Z., was bred in the Botanical Garden of the National Academy of Sciences of Kyrgyzstan from crossing varieties Aport and "King David", of late winter ripening. The trees are vigorous, varietal, bears fruit in the sixth year, bears fruit annually, the yield is high. Resistant to powdery mildew. Branches with an average angle of departure, brown shoots, medium pubescent. Variety with a mixed type of fruiting, enters fruiting early, yielding. Variety Rashida obtained in the Botanical Garden of the National Academy of Sciences of Kyrgyzstan from crossing the varieties Aport Alexander ½ Jonathan, the author is E.Z. Gareev.
