An evaluation of the field performance of the progeny of plants regenerated from embryos of Hordeum vulgare cv. Golden Promise

The study was designed to compare the agronomic performance of progenies of barley plants (cv. Golden Promise) regenerated from immature zygotic embryos (IE) with these originating from embryos produced after chromosome elimination (Hordeum bulbosum technique). Conventionally derived seed material was used as control. In a randomized complete block design with two replicates, plants were scored for mildew reaction (Erysiphe graminis f.sp. hordei), number of days to awn emergence, height and yield. Data showed no evidence of variation for mildew reaction and although significant differences between lines for the other three characters were observed in the IE-derived sample these were not significantly greater than that observed in the control samples
