Report on Breeding Columnar Apple Varieties
Abstract：An apple breeding program started at Laiyang Agricultural College in 1994, aiming at combining columnar growthhabit and other desirable characteristics in a new variety. Preliminary observation on the performance of the crossed progeniesshowed that the growth vigor; precocity; resistances to mildew,ring spot and woolly aphid varied greatly. The fruit size andshape, flesh firmness,eating quality, flowering date and fruit ripening date were apparently polygenic characters. An AFLPmarker of Co gene was selected and converted into SCAR marker, which could be employed to detect columnar genotype withhigher efficiency. Further trials of several promising selections are under way.
