Abstract

The invention provides a method for purifying and breeding a single variety of Pyracantha, selecting 2 to 3-year-old single-variety Pyracantha as the female parent for the first breeding, and growing seedlings through cuttings. The first female parent was cultivated; the second female parent L with lush growth was transplanted into lignified flowerpots; the female parent P with lush growth, plump fruit and single fruit color was selected for ceramic flowerpot transplantation. 3 times of female parent selection and 3 times of tissue culture can effectively improve the breeding purity of a single variety of Pyracantha. After the last female parent selection, routine Pyracantha pruning and cultivation are carried out to successfully breed Pyracantha with good growth, plump and plump fruits, and single fruit color. Large-scale pure-bred Pyracantha; and the purified single-variety Pyracantha has stable properties, and is not easy to mutate into other types of Pyracantha or appear mixed with multiple varieties of Pyracantha.
