Abstract

Centipedegrass (Eremochloa ophiuroides [Munro] Hack.) is an important warm-season turfgrass and pasture grass. To explore the potential use of biotechnical tools in breeding of centipedegrass, we established an efficient plant regeneration system for this species. Four basal media and 24 combinations of 2,4-dichlorophenoxyacetic acid (2,4-D) and 6-benzyladenine (BAP) were examined for their effects on callus induction from mature seed explants. Twenty combinations of naphthaleneacetic acid (NAA) and BAP were tested for their effect on plant regeneration. Results indicated that Murashige and Skoog basal medium supplemented with 4.5 mg l−1 2,4-D and 1 mg l−1 BAP was the best medium for callus induction, while the combination of 2 mg l−1 BAP and 1 mg l−1 NAA induced the highest rate of regeneration and development of shoots and roots. This work provides a basis for the breeding of centipedegrass through somaclonal variation and genetic transformation.
