Dear all,
Since Larking and Scowcroft coined the term somaclonal variation (SV) has passed a long time. Regardless it's considered a variation source, with a potential great repercussion for creation of new plant varieties, to the best of my knowledge, there's not registered varieties from SV. As likely I'm not so well informed, I would appreciate some information about it.
Thanks beforehand
Yes, somaclonal variation is the source of genetic variations but it is fully uncertain about the level and type of genetic variation.
Dear Mahipal Shekhawat thanks for your answer. The question is, is there any registered variety created from SV?

Dear Pendyala Chitralekha I'll read the paper carefully . Thanks!!!!
Dear Pendyala Chitralekha I can't find the papaer of Katiyar and Chopra 1995. If you have a copy, could you be so kindly to share it? Thanks beforehand.

In Table 3, of this attached 2016 Review paper, it gives a list of such plant varieties. Article Somaclonal variations and their applications in horticultura...
Dear Ricardo Julian Licea-Moreno,
I am sorry, I do not have a copy of the paper but I have requested my colleagues from the same lab to share the paper if they have.
Hoping that I will get a copy soon and share it with you.
Thanks very much to all the colleagues that have answered my question, specially to Yuan-Yeu Yau and Pendyala Chitralekha
Somaclonal variation provides a valuable source of genetic variation for the improvement of crops through the selection of novel variants, which may show resistance to disease, improved quality, or higher yield. https://www.intechopen.com/chapters/40179
Somaclonal variation is seen in plants that have been produced by plant tissue culture. Chromosomal rearrangements are an important source of this variation. ... Therefore, it can be defined as the variation that occurs because of genetic mutation caused by in vitro conditions or by chimeral separation. https://www.sciencedirect.com/topics/immunology-and-microbiology/somaclonal-variation
