Variation and best linear unbiased predictors in a novel source of orchardgrass germplasm with increased winter hardiness

Variation and best linear unbiased predictors in a novel source of orchardgrass germplasm with increased winter hardiness

Evaluation of orchardgrass families at two Utah locations identified significant genetic variation for winter injury but not for flowering or biomass production. Repeatability estimates ranged from 0.06 (biomass production) to 0.65 (winter hardiness). This population has utility for the development...

Zusammenfassung:Evaluation of orchardgrass families at two Utah locations identified significant genetic variation for winter injury but not for flowering or biomass production. Repeatability estimates ranged from 0.06 (biomass production) to 0.65 (winter hardiness). This population has utility for the development of cultivars with increased winter hardiness.
