I. Course Title
: Seed Quality Testing and Enhancement*
II. Course Code
: SST 509
III. Credit Hours
: 2 (1+1)
IV. Why this course?
Seed is the basic input in agriculture and the productivity is mainly depends on
field population of plants. By sowing quality seeds, population can be maintained.
Hence, it is necessary to know the quality parameters to be analyzed. Through
seed treatments, the performance of seed can be improved. Especially to address
the drought and climate change the knowledge on seed enhancement techniques is
much essential.
V. Aim of the course
To impart knowledge on principles, techniques and methods of seed testing and
seed quality enhancement.
VI. Theory
Unit I
Seed testing – history and development; seed testing in India; ISTA and its role
in seed testing; seed lot and size, types of seed and size, samples – sampling –
intensity and methods, sampling devices, receipt and registration of submitted
samples in the laboratory and sub sampling; purity analysis – components and
procedure – determination of other distinguishable varieties (ODV) and test weight
determination – application of heterogeneity test – method of testing coated and
pelleted seeds; seed moisture estimation – principles and methods, application of
tolerances.
Unit II
Seed germination test – requirements, media and methods – seedling evaluation,
tolerance and reporting results; viability test (TZ test) – principle, procedure and
evaluation; vigour tests – concept of seed vigour and vigour test – types of vigour
tests – direct and indirect tests – physical, physiological and biochemical tests –
principles and methods; seed health test – principles and methods.
Unit III
Genetic purity assessment – laboratory methods – physical, chemical, biochemical
and molecular tests – growth chamber and field testing (Grow Out Test) methods;
testing of GM seeds; storage of guard sample – referral test; application of tolerance
in seed testing; advanced non destructive techniques of seed quality analysis – soft
x-ray imaging – hyper spectral imaging, thermal imaging – spectroscopy – e-nose
and machine vision techniques.
