“…Similarly, Shepard et al (1980) suggested that field evaluation of large populations of 60,000-80,000 seedlings was necessary for the identification of one promising seedling-based clone (0.000012%-0.000016%). In contrast, Thieme and Griess (2005) estimated that 5,000-10,000 somaclones are required to obtain one new variety (0.0001%-0.0002%). Our results from field evaluation of somaclones suggest that the extreme numbers used for seedlings may not be essential to obtain improved clones but the effort and expense remain considerable.…”

“…From 2% to 10% of calliclones were superior to control genotypes for haulm growth, earliness, and tuber yield. Only 0.1%-1.4% of calliclones were better than control genotypes for a range of tuber characters (Thieme and Griess 2005). A variant of 'Russet Burbank' with resistance to potato leafroll virus was selected from a population of calliclones and released in Canada in 2002 as 'AC LR Russet Burbank' (Plant Breeders' Rights Office 1997;CFIA 2008).…”

Russet Burbank' has limited fertility and has not parented improved cultivars through traditional breeding efforts. This study showed that 'Russet Burbank' (NB clone) could be improved through selection of intraclones (somatic embryos derived from specific tuber tissues) based on field performance and/or processing characteristics. In 2005 and 2006, approx. 800 intraclones were regenerated from field-grown tubers or microtubers. Intraclones were micropropagated, acclimatized, and field-tested to identify the highest yielding lines. Each season, following storage, tubers of selected lines were tested for glucose content and French fry-processing quality. In 2007, the best intraclones from earlier seasons were increased through micropropagation and retested for yield and processing features. Approx. 2-9% of intraclones had similar yield to controls but superior processing features. Neither tuber source nor explant tissue type affected intraclone tuber yield, type, or processing characters. We recommend the incorporation of somatic embryogenesis into potato improvement programs for processing quality traits.Resumen "Russet Burbank" tiene fertilidad limitada y no ha sido progenitor que haya mejorado variedades a través de esfuerzos de mejoramiento tradicional. Este estudio demostró que "Ruset Burbank" (clon NB) pudo mejorarse por selección de intraclones (embriones somáticos derivados de tejidos específicos de tubérculo) con base en el comportamiento en el campo y/o en características de procesamiento. En 2005 y 2006, se regeneraron aproximadamente 800 intraclones de tubérculos cultivados en el campo o de microtubérculos. Los intraclones se micropropagaron, se aclimataron, y se probaron en el campo para identificar las líneas de rendimiento más alto. En cada ciclo de cultivo, después del almacenamiento, se probaron tubérculos de líneas selectas para el contenido de glucosa y de calidad de fritura para papas a la francesa. En 2007, los mejores intraclones de siembras previas se incrementaron por micropropagación y se volvieron a probar para rendimiento y características de procesamiento. Aproximadamente el 2-9% de intraclones tuvieron rendimiento similar al de los testigos pero mejores características de procesamiento. Ni la fuente del tubér-culo ni el tipo de tejido del explante (inóculo) afectaron el rendimiento de tubérculo de los intraclones, o el tipo o características del procesamiento. Recomendamos la incorporación de embriogénesis somática en los programas de mejoramiento de papa para las características de calidad en el procesamiento.

“…As a result, some of the resultant somaclones can possess desirable traits that remain stable and are heritable by progenies (Rietveld et al 1993;Roy and Mandal 2005). In addition, induction of somaclonal variation has been successful at identifying potential new varieties in different crops such as potato (Arihara et al 1995;Thieme and Griess 2005;Wang et al 2007) and millet (Baer et al 2007). Most importantly, tissue culture increases the efficiency of mutagenic treatments for variation induction, allows handling of large populations and rapid cloning of selected variants under high phytosanitary conditions (Predieri 2001).…”

Plant tissue culture has become one of the fundamental tools of plant science research. It is extensively employed in the production, conservation and improvement of plant resources. The presence of somaclonal variation in populations derived from tissue culture is affecting the use of tissue culture negatively and has remained a major problem. Conversely, it is a source of new desirable clones/variants with better agronomic traits. In this review, we summarize the possible causes, detection methods and desirability of variants. Somaclonal variation is one of the most researched and reviewed topics. Hence, we restricted ourselves to outlining various examples which may be used as important references for researchers who intend to identify and/or characterize somaclonal variants while using tissue culture for research and production. Emphasis is placed on the negative effects of somaclonal variation. However, this review also includes examples of some useful variants generated as a result of somaclonal variation.

The advancements made in tissue culture techniques has made it possible to regenerate various horticultural species in vitro as micropropagation protocols for commercial scale multiplication are available for a wide range of crops. Clonal propagation and preservation of elite genotypes, selected for their superior characteristics, require high degree of genetic uniformity amongst the regenerated plants. However, plant tissue culture may generate genetic variability, i.e., somaclonal variations as a result of gene mutation or changes in epigenetic marks. The occurrence of subtle somaclonal variation is a drawback for both in vitro cloning as well as germplasm preservation. Therefore, it is of immense significance to assure the genetic uniformity of in vitro raised plants at an early stage. Several strategies have been followed to ascertain the genetic fidelity of the in vitro raised progenies comprising morpho-physiological, biochemical, cytological and DNA-based molecular markers approaches. Somaclonal variation can pose a serious problem in any micropropagation program, where it is highly desirable to produce true-to-type plant material. On the other hand, somaclonal variation has provided a new and alternative tool to the breeders for obtaining genetic variability relatively rapidly and without sophisticated technology in horticultural crops, which are either difficult to breed or have narrow genetic base. In the present paper, sources of variations induced during tissue culture cycle and strategies to ascertain and confirm genetic fidelity in a variety of in vitro raised plantlets and potential application of variants in horticultural crop improvement are reviewed.
