| Abstract | Temperate grasses need an extended exposure to low temperature (i.e. vernalization) in order to properly regulate the transition from vegetative to reproductive growth. In barley and other cereals there are several methods to measure the sensitivity or response to the vernalization. The three most commonly used phenotypes are the double ridge stage of meristem development (Kirby and Appleyard 1987), heading date (Wehrhahn and Allard 1965), and final leaf number (FLN) (Wang et al. 1995). Heading date is the simplest to measure however maturity genes may influence the measurement. While the double ridge method is the most accurate, it is extremely time consuming and results in the loss of the plant. Therefore, final leaf number (FLN) was used to measure the phenotype on two populations: Dicktoo x OWB-D and Dicktoo x Calicuchima. Heading date was measured on the same populations (Szűcs et al. 2007) and these results were compared using a statistical correlation to show if the maturity genes had a significant effect on the data from the heading date results. |
