| Abstract/Contents: | "Tetraploid apomictic bahiagrass (Paspalum notatum Flugge) cultivar "Argentine" is a prime low-input and drought tolerant turf and forage species. However, the turf quality of bahiagrass is limited by its open growth habit, light green color and prolific production of tall seedheads. Genetic improvement by conventional breeding is very di cult due to its apomictic mode of reproduction. Our objective was to explore the potential of in vitro chemical mutagenesis for generation of uniform mutagenized seed progeny with improved turf quality. Scarified and surface sterilized bahiagrass seeds were treated with different concentrations of the mutagen sodium azide. Callus was induced from these seeds and regenerated via somatic embryogenesis to obtain uniformly mutagenized plants. 2,000 of the 20,000 regenerated seedlings were selected based on their morphological characteristics and transferred to soil. 46 independently mutagenized lines (M1 lines) with reduced stem length, higher tiller density or reduced or delayed seedhead formation were established under field conditions in 1.2m x 1.2m plots in a randomized block design with 4 replications for further evaluation of density, leaf texture, tiller length, color, growth pattern, biomass, seedhead and seed production, as well as seedling vigor. Mutagenized lines with improved characteristics and production of viable seed were identified and their apomictic M2 progeny was evaluated in 3m x 3m plots. The superior line displayed higher density, finer leaves, an upright growth habit, dark green color, reduced seedhead formation and uniform seed progeny. This line also retained the superior drought tolerance and persistence of bahiagrass." |
