[0003] Pyracantha belongs to cross-pollinated plants. Planting the same species of Pyracantha in the same plantation will easily lead to confusion of Pyracantha species, such as the whole Pyracantha fruit with red and yellow, and the Pyracantha with small crenulate yellow and red. Cause the non-existence of a single species of Pyracantha, and the ornamental value declines

Embodiment 1
[0028] In the present embodiment, Pyracantha scutellaria, which grows luxuriantly, has plump and plump fruits, and is completely orange in color, is selected as the female parent for the first breeding.
[0029] The specific purification and breeding steps of the present embodiment are as follows:
[0030] Step 1. Select a 2-3-year-old single-variety Pyracantha sinensis with lush growth, plump and plump fruit, complete orange color, as the female parent, and cut the lignified branches of the female parent in late January to make cutting ears. Cut the bottom end into a horse-ear shape, apply yellow soil on the incision, and soak in the growth liquid for 12 hours. When soaking, the growth liquid is immersed in the place 2 cm above the bottom of the cutting ear;
[0031] Step 2: In the frame greenhouse, a seedbed of 3 × 1m is set in the shed, a strong light irradiation device is arranged at a distance of 3m from the seedbed above the seedbed, and a 15cm thick cultivation matrix i...
Embodiment 2
[0049] In the present embodiment, Pyracantha japonicus Pyracantha entire margin with lush growth, plump and plump fruit, and bright red national color is selected as the female parent for the first breeding.
[0050] Adopt the same method of purification and breeding of Pyracantha species as in Example 1, this implements 1000 plants of Pyracantha chinensis with cuttings and seedlings, 948 plants of cuttings survive, and 948 plants of surviving cutting ears are completely transplanted to black plastic flower pots; the second female parent During the cultivation, the female parent L group contained 713 plants of Pyracantha entire margin, and 713 plants of Pyracantha entire margin were transplanted into wooden flowerpots, and 713 plants survived; There were 568 plants of Pyracantha full-margin with lush, plump and plump fruits, and the fruit color was completely bright red.

Abstract
The invention provides a purifying propagation method for single-variety pyracantha fortuneana. According to the method, 2-3-year-old single-variety pyracantha fortuneana with flourishing growth vigor, full and obese fruits and single fruit color is selected as maternal plants for first-time culture, and the first-time maternal plants are cultured in a cuttage seedling propagation manner; second-time maternal plants L with flourishing growth vigor are transplanted with lignified flowerpots; and maternal plants P with flourishing growth vigor, full and obese fruits and single fruit color are transplanted with ceramic flowerpots. By 3-time maternal plant selecting and 3-time tissue culture, the propagation purity of the single-variety pyracantha fortuneana is efficiently improved; through carrying out routinized pyracantha fortuneana pruned culturing after last-time maternal plant selecting, large-sized pure-variety pyracantha fortuneana with good growth vigor, full and obese fruits andsingle fruit color is successfully cultured; and the purified single-variety pyracantha fortuneana is stable in traits and is not prone to current situations that the single-variety pyracantha fortuneana is mutated into pyracantha fortuneana of other varieties or multiple varieties of pyracantha fortuneana occur in a mixed manner.
