Biomass production potential in the Batini barley landrace from Oman

Diversity available in seven subpopulations of the Batini barley landrace was quantified for pre- and post-anthesis thermal time, filling period, biological and grain yield, number of tillers and plant height.‎ We identified grain, forage and dual-purpose types and selected elite germplasm for breeding purposes.‎ Patterns of phenotypic variation and co-variation in the phenological and agronomic traits, measured on 2,040 landrace accessions, subdivided the collection into 14 phenological classes in three (grain, dual-purpose and forage) end-use types, each with distinct phenological trait combinations.‎ The dual-purpose type was more polymorphic and significantly had higher total diversity and differentiation than the grain and forage types.‎ Directional selection, especially in the phenological traits, resulted in large, idiosyncratic changes in plant phenotypes.‎ Targeting traits that have a disproportionately large influence on differences in the mean covariance will help identify sources of variation for breeding purposes.‎
