The study of the genetic effects in generation of pea plants cultivated during the whole cycle of ontogenesis on the board of RS ISS

Results of studies on growth and development of offspring of two genetically marked dwarf pea lines planted during the whole ontogenesis cycle in the Lada space greenhouse on board of Russian Segment of International Space Station (RS ISS) are presented. The offspring of M1 and M2 plants grown from seeds formed during space flight was examined under conditions of Earth-based cultivation. It had been shown that growth and developmental characteristics, frequency of chromosome aberrations in primary root meristem and level of molecular polymorphism revealed in individual plants via RAPD method show no significant differences between offspring of 'space-grown' and control seeds.
