Abstract/Contents:"Weak cold-resistance of centipedegrass is one of the major factors limiting its wide application. This study aimed to obtain cold-resistant somatic mutants from the seed of eminent Chinese native centipedegrass selection E-126 by induction and screening at low temperature. The callus induced by seeds of centipedegrass was cultivated at 0°C for 26 d during the process of subculture and two pieces of survival callus tissues were obtained. Strain 1 and strain 2 were obtained after survival callus subculture proliferation, differentiation, rhizogenesis and transplantation. No significant differences were found in leaf color, lamellar hair, leaf length and leaf width between strains 1 and 2 and the control. LT50 of strains 1 and 2 were -6.646 and -6.546 °C, respectively, which was significantly lower than that o control plants (-5.351°C) and there was no significant difference between the LT50 of strains 1 and 2. The results of sequence related amplified polymorphism (SRAP) markers demonstrated that there were identical characteristic bands at 110, 230 and 240 bp of centipedegrass strains 1 and 2 obtained through low temperature induction. However, no characteristic bands at 110, 230 and 240 bp were found in control plants, indicating that the somatic mutants of centipedegrass were genetically stable compared with that of control plants at a molecular level. Strains 1 and 2 could be utilized as identical strains."
