Morphological markers with a triploid set of chromosomes by breeding of apple tree at the polyploid level

The results many years of research in the conditions of the Altai low mountains are given the assessment of hybrid apple populations from heterploid crosses according to the characteristics: resistance to scab, degree of culture, growth strength, stem thickness, leaf thickness, leaf index, morphomet...
