Description
The genetic variability within two adapted populations of tall wheatgrass (Thinopyrum ponticum) was evaluated in Argentina, as an introductory part of a breeding programme in progress at our Institute. The final aim of this programme is to provide new cultivars of tall wheatgrass, adapted to different management systems. Two hundred fifty plants per population were grown from seeds, clonally propagated and transplanted as a spaced-plant trial in a randomized design with three replicates. The results indicated large differences between genotypes within the two populations for most attributes measured, though there were no significant differences between populations. Attributes related with forage yield, forage quality and seed production had high to medium broad-sense heritability values, suggesting the importance of including the adapted germoplasm in the breeding programme in progress at INTA.
