I found russian article about somatic hybrid C. Limon x P. trifoliata, it has also very different seedlings, somatic hybrid seems to me similar to chimera, I think seedlings from Prague chimera may have similar percentages of seedlings with trifoliate and mandarin look..
1. distant hybrid No. 104 of Georgian lemon with trifoliata is the first in the selection practice of citrus forms with edible fruits with prevailing morphological features of the cultural component.
2. On hybrid No. 104 different shoots are observed at growth: phenotypically lemon (40%), trifoliate (1%) and intermediate shoots, i.e. self-like (59%).
Leaves on the tree of the above-mentioned hybrid are different, varying from simple one-plate to complex - two and three-plate. In winter, the shape is characterized by semi-leafiness, with most of the fallen leaves being complex.
3. According to flowering biology the named hybrid is a remontant plant, but it blooms 2-3 times in mass during the spring-summer period.
4. Hybrid No. 104 is characterized by an earlier ripening of the harvest compared to the Georgian lemon. At the same time it has good taste and biochemical indicators of pulp, although slightly inferior to the original cultural parent in size and shape of the fruit.
5. The named hybrid has relatively high frost resistance, 3-4 °C higher than lemon Georgian, which is confirmed by data obtained in the laboratory of artificial climate.
6. Plants of this hybrid also have high productivity, approximately 2.5 times higher than control. Even in frosty winters, when Georgian lemon plants were badly damaged, Hybrid No. 104 exhibited normal fruit bearing.
7. When Hybrid No. 104 multiplied by grafting bud taken from lemon-type shoots, a form phenotypically similar to a lemon is formed. In its seed offspring the following morphological groups of seedlings are formed: I - lemon type - 92.4%, P - lemon-like - 6.1%, W - intermediate 1.1% and 1U - trifoliates - 0.4%.
8. In the seed generation of hybrid No. 104 a great variety of forms is observed, from phenotypically pure lemon to phenotypically pure trifoliate, from which five groups can be distinguished by the degree of manifestation of signs of the initial components: I - morphologically of lemon type - 54,0%, P - lemon-type inclined - 43,8%, W - intermediate type - 0,8%, 1U - trifoliates inclined towards - 1,0%, U - morphologically of trifoliate type - 0,4%.
9. Frost resistance of these forms increases as they incline towards trifoliate, and decreases accordingly as they incline towards lemon. However, as the degree of trifoliate signs dominates, the quality of the fruit deteriorates, and vice versa. However, among the forms evading the cultural component, some exhibit relatively higher frost resistance, maintaining good fruit quality.
10. Variety in seed offspring and emergence of forms with predominance of features of the cultural component on a large scale gives us the right to use hybrid No. 104 for breeding purposes, which excludes laborious interbreeding works.
The closer the form is phenotypically to one of the primary source parents (lemon or trifoliate), the more individuals with predominant features of a dominant ancestor appear in its seed offspring.
12. When selecting economic forms according to the complex of correlated features, preference is given to forms mainly with one-plate leaves, which partially show signs of trifoliate but retain a pleasant lemon smell.Translated with www.DeepL.com/Translator
