Problems solved by technology

[0002] Pansy is a perennial herb of the Viola family Viola genus. It is also known as pansy flower, cat face, and grimace flower. It is native to southern Europe. The flower color is bright and colorful, and it is often cultivated as one or two years. It is widely used in flower beds, flower borders, and cut flowers. It grows well under the conditions of ℃~25℃ and night temperature 3℃~5℃. It has been widely cultivated as an ornamental plant in the world. With the improvement of science and technology, the breeding technology of pansy is also constantly improving. Because the pansy belongs to the ornamental plant, the conventional breeding method can not bring out the unique effect of the color, and the current hybrid seed production cycle is long, which seriously affects the need for its multiplication.

Embodiment 1

[0024] A kind of breeding method of pansy, comprises the steps:

[0025] (1) Manual removal of male petals: From the side of the semicircular arc of the flag petal, use tweezers to clamp the top of the flag petal and the connection between the flag petal and the flower statue. The angle between the tweezers and the flower back line is 40-50 degrees. Then clamp the petals and pull them all out. The direction of force when pulling out is consistent with the direction in which the pansy flower grows;

[0026] (2) Measure pollen viability of artificially emasculated flowers, stain with TTC solution, take samples from the field every 3 hours from 8:00 in the morning, mix pollen from 3 flowers each time, and dye for 1 hour at room temperature After microscopic examination, it was dyed deep red and considered to be viable, counted 5 visual fields, and calculated the average value. The percentage of viability of pollen is represented by staining rate;

[0027] After measuring, the p...

[0050] A kind of breeding method of pansy, comprises the steps:

[0051] (1) Manual removal of male petals: From the side of the semicircular arc of the flag petal, use tweezers to clamp the top of the flag petal and the connection between the flag petal and the flower statue. The angle between the tweezers and the flower back line is 40-50 degrees. Then clamp the petals and pull them all out. The direction of force when pulling out is consistent with the direction in which the pansy flower grows;

[0052] (2) Measure pollen viability of artificially emasculated flowers, stain with TTC solution, take samples from the field every 3 hours from 8:00 in the morning, mix pollen from 3 flowers each time, and dye for 1 hour at room temperature After microscopic examination, it was dyed deep red and considered to be viable, counted 5 visual fields, and calculated the average value.

Abstract

The invention discloses a breeding method for pansy. According to the method, manual castration is performed on pansy flowers and then hand pollination is performed, pansy breeding is quickened through a tissue culture technique, one-time pulling out of petals is achieved and the castration success rate is high by a reasonable castration method, the condition of ovary damage is absent, and thereby, working efficiency and hybridization burliness success rate are high. The working efficiency is over 2 times higher than that of traditional methods, and the hybridization burliness success rate is nearly one time higher than that of traditional methods. Bagged isolation is not required, manpower can be saved, the breeding process is accelerated through tissue culture and rapid propagation methods, and economic benefits are greatly improved.

Description

technical field [0001] The invention belongs to the field of plant breeding, and in particular relates to a pansy breeding method. Background technique [0002] Pansy is a perennial herb of the Viola family Viola genus. It is also known as pansy flower, cat face, and grimace flower. It is native to southern Europe. The flower color is bright and colorful, and it is often cultivated as one or two years. It is widely used in flower beds, flower borders, and cut flowers. It grows well under the conditions of ℃~25℃ and night temperature 3℃~5℃. It has been widely cultivated as an ornamental plant in the world. With the improvement of science and technology, the breeding technology of pansy is also constantly improving. Because pansies belong to ornamental plants, conventional breeding methods can not bring out the unique effect of color, and the current hybrid seed production cycle is long, which seriously affects the needs of its proliferation.
