This document outlines the importance of selecting high-quality seeds for agricultural success, particularly in rice cultivation, detailing characteristics of good seeds, such as high germination rates and genetic purity. It classifies seeds into four categories: breeder, foundation, registered, and certified, emphasizing that pure and disease-free seeds yield better crop results. Additionally, it highlights the necessity of seed viability testing to ensure effective germination before planting.

INTRODUCTION
Using high quality seeds of a recommended rice variety
will result in a considerable increase in the yield.
Seeds of improved variety should be certified by the
National Seed Quality Control Services (NSQCS). It could
be proven through a blue card attached to the sack.

High Germination Rate
Seeds should have the ability to sprout
and grow into healthy plants.
The percentage of seeds that germinate
is crucial. High-quality seeds will have a
higher germination rate, usually above
80%. This ensures most of the seeds
planted will develop into plants.

Purity
Seeds must be free from other seeds,
weeds, or foreign materials.
A good seed should be pure, containing
only the seeds of the desired crop without
contamination. This helps in ensuring that
only the intended crop grows and
prevents competition with weeds.

High Genetic Purity
The seed should belong to the desired
variety or hybrid.
Genetic purity ensures the seed will
produce the exact type of plant with the
expected qualities, such as size, yield,
and resistance to certain pests or
diseases.

Hybridization means that a

during the reproductive stage,
it is crossed with another plant.

Seeds should have a consistent size and

Uniform seeds generally have better
germination and growth rates. It ensures
that seeds will be planted at the same
depth and sprout at similar times, leading
to uniform crop growth.

Viability
The ability of a seed to grow into a plant
after a period of storage.
High-quality seeds can remain viable for
long periods under proper storage
conditions, meaning they retain their ability
to germinate even after being stored for
some time.

VIABILITY
Before sowing it is highly
recommended that a test be
conducted to determine the viability
of the seeds. Many seeds fail to
germinate because they have been
kept too long under bad conditions.
Every plant grower should determine
the germinating power of seeds by
testing them to ensure high
percentage of germination, less
expenses, time and effort.

Moisture Content
Seeds should have the right level of
moisture.
High moisture content can lead to fungal
growth, while too little moisture can
reduce seed viability. Properly dried seeds
(usually 10-12% moisture content) are ideal
for storage and planting.
