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.

“…Somaclonal variation is in general a potentially useful source of genetic variability for plant improvement and could result in new genotypes. Several cases of somaclonal variation for disease resistance traits have been reported in temperate fruit species (Hammerschlag, 1992): apple rootstocks resistant to Phytophthora cactorum (Rosati et al, 1990), apple cultivar 'Greensleeves' to fire blight resistance (Donovan et al, 1993), peach seedlings resistant to Pseudomonas syringae pv. syringae (Hammerschlag, 1992) or to Xanthomonas campestris pv.…”

Decreasing the application of agrochemicals, especially pesticides, in fruit growing practices is one of the most important problems placed by the European Commission of Agriculture with the aim of preserving human health and protecting the environment. The problem is a matter of urgency in the apple crop, which occupies a leading position by the number of pesticide treatments. Solving the problem necessitates the establishment of cultivars resistant or tolerant to the major diseases and pests. The aim of the present study is to test the resistance of in vitro obtained apple regenerants 'Čadel' ® , to the most widely distributed phytopathogens in apple-scab (Venturia inaequalis), powdery mildew (Podosphaera leucotricha) and fire blight (Erwinia amylovora). Varying concentrations of monospore cultures of the respective fungal pathogens isolated from naturally infected leaves and most aggressive bacterial strain from Bulgaria are used in the investigation. The acclimatized in vitro somaclones, 8-10 cm in height or at the 4 th-5 th true leaf development stage, are inoculated with the respective phytopathogens following standard or improved methods. It is established that 3 out of the studied clones demonstrated a complex resistance to scab and powdery mildew diseases and low susceptibility/ tolerance to the dangerous bacterial disease fire blight.

“…The development of an efficient system for adventitious shoot regeneration from somatic plant tissues is an important prerequisite for the successful application of plant genetic manipulation methods such as mutation breeding (3,4,17), somaclonal variation (9,24) or genetic transformation (8,11,13,15). The utilization of root explants may be advantageous with respect to the production ofhomohistont plants (2,3), less oxidation after excision and ease of manipulation (27) and in cases when other explants can not be used with success (25).…”
