Development and comparative assessment of regenerated lines of cucumber

Application of such biotechnological method as a callus culture, allowed developing the somaclonal variants of cucumber, six of which were selected as a regenerated lines for the breeding program. New forms are characterized by early-ripeness, percent of parthenocarpy, good quality, yield and fruit weight. These lines can be used as an initial material for heterosis breeding and for improvement of donor cultivars of cucumber.
