High quality seed can be defined as the ability of seed to germinate
vigorously and provide normal seedling and uniform crop establishment
under wide range of environmental conditions. This complex trait results
from a sound genetic background, good practice during seed production,
favorable environment during development on the mother plant, optimal time
of harvest, appropriate processing and storage. To identify seed quality
marker(s) which will predict the seed quality has been a challenging task for
seed researchers for a long time which has not been successfully
accomplished yet. Therefore, testing germination and other traits in seed
testing laboratories is still the only reliable source of information on seed
quality. For commercial testing are developed standard methods aiming to
provide good prediction of seedling establishment in the field. Very often,
there are several standard methods developed for testing seed germination of
one plant species. The...y can differ in germination substrate or temperature
applied during the testing. In most cases, irrespective on testing conditions,
seed quality will not differ significantly; however, at seed lots with declining
quality testing conditions applied can be highly discriminative. Since the
seed quality depends on more than one factor, it is understandable that it is
not targeted in the breeding programs, however, efforts should be constant in
identifying the impact of genetics on this trait and be focused on varieties
which have potential in providing high seed quality.
