Head cabbage androgenic genotypes of R1 and R2 generations derived from Jaguar F1 donor hybrid were evaluated according to their agroeconomical characters, ability for generative propagation, self-incompatibility, intraline uniformity and stability of morphological characters. Most of R1 and R2 genotypes had desired morphological characters. However, in R1 generation 21 lines showed lack of int...

Somaclonal variation that possibly occurs during the process of plant tissue culture is considered to provide a source of new germplasm. Polyploidy is one of the most frequent incidents among the somaclonal variations. In the present study, we performed cytological and morphological characterization of tetraploid plants that were obtained from long-term subcultured callus culture of Lilium long...

While genotype-environment interaction is increasingly receiving attention by ecologists and evolutionary biologists, such studies need genetically homogeneous replicates-a challenging hurdle in outcrossing plants. This could be potentially overcome by using tissue culture techniques. However, plants regenerated from tissue culture may show aberrant phenotypes and "somaclonal" variation. Here, ...

Mantled fruits as a result of somaclonal variation are often observed from the oil palm plantlets regenerated via tissue culture. The mantling of fruits with finger-like and thick outer coating phenotypes significantly reduces the seed size and oil content, posing a threat to oil palm planters, and may jeopardize the economic growth of countries that depend particularly on oil palm plantation. ...
