Dwarf close planting cultivation is widely adopted in developed countries of the apple industry, dwarf stocks are basically and completely applied to newly built orchards of major apple producing countries in the world at present, most countries account for more than 90% of the total area of apples, and dwarf close planting cultivation is adopted in 100% of European apple production.
The apple seedling stock is widely applied in China, the seedling seedlings are almost used as the stock even if the dwarf interstock is dwarfed, and the apple stock seeds are not considered to transmit viruses in the past. In recent years, the rates of apple rust viruses detected by the seedlings of the Malus micromalus, the Malus spectabilis and the Malus hupehensis are respectively 30%, 26.7% and 100%; the toxicity rate of the catalpa bungei seedlings is 73.3 percent, and the complex infection rate of apple stem pox virus, apple chlorotic leaf spot virus and apple rust virus is 53.3 percent. The main way of culturing virus-free nursery stocks is to breed without seeds.
The breeding of the apple stock excellent variety is mainly carried out by asexual propagation through methods such as layering, grafting, tissue culture, cuttage and the like. The developed national apple rootstocks in the foreign apple industry generally adopt layering propagation. Cuttage is a rapid and simple stock rapid propagation method.
