- Physical quality- The seeds should remain free from any undesired element like- diseased seed, dirt and dust along with proper processing i.e, grading.
- Physiological quality- This includes seed germination and vigor. The ability of seeds to produce seedlings under normal condition with normal root and shoot is known as germ inability. While seed vigor determines the performance of seed during seedling emergence.

- Hybrid seeds- They are formed from the cross pollination b/w two type of similar plants. They generally offer good growth and higher yield. Hybrid seeds are unstable and cannot be used in following years.
- GMO seeds- Genetically modified seeds are developed in lab using modern technologies. The main objective is to create a pest resistant plants, in this process crosses are made between a bacteria and plant. They are used extensively in organic farming.
