The complex trait of seed vigour is a key component of crop seed performance. The term "seed vigour (triebkraft)" was coined by Nobbe in 1876 and ISTA (2001) defines it as "the sum of those properties that determine the activity and performance of seed lots of acceptable germination in a wide range of environments".

Vigour is a concept that includes characteristics associated the rate and uniformity of seed germination and seedling growth, emergence ability of seeds under unfavourable environmental conditions and performance after storage, particularly the retention of the ability to germinate (ISTA 2001). Vigour can therefore influence both crop yield and its marketable quality. While our knowledge about the mechanisms of seed germination and dormancy has greatly advanced, our understanding of the mechanisms of seed vigour remains limited.
