Abstract: | Summary The effect of pre-vernalisation growth (pre-growth) period on time of flowering was examined in four lines of swedes. No effect was found with the line from cv. Marian. The lines from cvs. Ruta Øtofte and Bangholm Wilby showed increases in time to flowering with increased pre-growth period; maximum delay occurred with 4 wk and 6 wk pre-growth, respectively. Most plants from a line of cv. Criffel showed no effects, but a small proportion did show long delays with pre-growth. |
