So how can we correctly breed for the colored magnolia?

I. 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.

Second, the choice of female parent.

Based on the previous experience, the female parent first chooses 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 better the other conditions are in line with the standard of Magnolia.

Third, the choice of paternal parents

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.
