Breeding Techniques of Colored Clivia

Color channel distribution is uniform: White and green, there should be a certain proportion.

The color channel has a good contrast: green and white, bright and charming, exquisitely carved, with a sense of three-dimensional, transparency and freshness.

The stability of the color channel is good: the color channel distribution of chimera orchid is more uniform on each leaf, and the closer each leaf is, the better.

The color of Cailan is roughly divided into five types: wheel Road, Yuanyang Road, Caidao, Golden Road, and there are national orchid, Japanese orchid, Henglan, sparrow orchid and other strains. In breeding, color requirements and variety characteristics must be considered, and parents must be selected carefully. Some breeding experiences of our predecessors are summarized as follows.

Selection of parents

Since the emergence of colored orchids in the 1980s, the hybrid emergence rate has been 15%-20%. Only when plants with fairly uniform color stripes are selected as female parents, the emergence rate can reach 70%. Therefore, in the selection of parents, it is necessary to comprehensively consider the characters between the father and the mother, so that the characters complement each other, so that it is possible to get excellent orchid seedlings.

The choice of female parent

According to the previous experience, the female parent should first choose the silk orchid which is very transparent, which can penetrate through the front and back, and requires uniform distribution of color channels and high color purity; the larger the contrast between porcelain white and dark green, the better. Secondly, other characters are considered, such as leaf length, width, ratio of length to width, leaf vein, head shape, seat type, brightness, thickness, stiffness and so on. In the case of ensuring the emergence rate of offspring and the higher the ratio of Cymbidium, the more other conditions meet the standard of Cymbidium, the better.

The choice of male parent

Choose the male parent, first choose the more thorough silk orchid. Secondly, it is considered that the defects of the female parent characters can be compensated, reformed and enhanced. In the production practice, it will be found that the quality of some male parents is very good, but the offspring obtained from different female parents are different. Therefore, the choice of good paternal parents can only be determined after long-term practice, recording, observation and summary.

Hybrid technology

The magnolia does not bear fruit by itself and needs artificial pollination. After the selection of parents, the implementation of correct pollination techniques in order to obtain a large number of fruits.

Make preparations before pollination

Before pollination, prepare the necessary pollination tools: toothpicks, writing brushes, glass dishes, tweezers, labels, pencils or ballpoint pens. It is necessary to prepare more pollination tools when blooming, and be sure to make sure that a male parent uses a set of pollination tools. Determine the best pollination time

The stigma of the pistil began to secrete mucus 2-3 days after the perianth of the female parent was dehiscent, and the pistil matured, which was the best time for pollination. The best time of day for pollination is from 9 am to 10:00 or from 13:00 to 14:00 in the afternoon.

Collect pollen in time

When the stamens of the male parent emerge from the perianth, the anthers crack and the pollen begins to disperse, remove the stamens of the male parent with tweezers, pop the yellow pollen into a glass dish and cover it for use. It is not too late to collect pollen, and it is easy to lose pollen too late.
