An a:gronomically undesirable trade-off exists between yield, particularly in autumn, and winter hardiness. An understanding of the genetic control of plant growth and winter hardiness using a combination of quantitative genetics and linkage analysis could help improve both characters simultaneously (Brummer et al. 2000).
