| Abstract/Contents: | "Cynodon transvaalensis is important as all interspecific hybrid bermudagrass cultivars (e.g., Tifway, Latitude 36, etc.) extensively used in the turf industry were created by crossing it by common bermudagrass (C. dactylon). Improvement in the winter hardiness and drought resistance of bermudagrass will significantly benefit the turfgrass industry. However, the genetic basis for the important traits of this species is unknown. Accordingly, the objectives of this study were to estimate heritability and identify quantitative trait loci (QTL) associated with morphological and adaptive traits. A first-generation self-pollinated population of 109 individuals was evaluated for plant height, leaf blade width and length, stem internode length and diameter, spring greenup, winterkill, and leaf firing in a replicated field trial over three seasons (2017-2019). Significant genetic variances were found for all traits, and the broad-sense heritability estimates ranged from 0.32 to 0.81. Totally, 27 QTLs were identified for the traits, and 11 of them were recurrent QTLs. Co-localizations were found among QTLs associated with different traits, partially explained significant correlations between them. The results provide important genetic information and resources towards understanding the genetic basis of the traits of interest as well as marker-assisted selection for breeding new turf bermudagrass cultivars." |
