Foundation seed is produced from:

✅Explanation:
Foundation seed is the second generation in a seed multiplication system, following the breeder seed. It is produced from breeder seed under strict regulations and supervision to ensure high genetic purity and quality. Breeder seed, on the other hand, is directly derived from the nucleus seed, which is the original source of the desired plant variety and maintained by research institutions or breeding programs.

• Explanation of 📌Other Options:
-Nucleus seed: This is the initial source of the variety and not used directly for large-scale production.
-Registered seed: This is the third generation in the system, produced from foundation seed and used for further multiplication to get certified seed.
-Certified seed: This is the final generation, commercially available for farmers and growers. It is produced from registered seed and meets specific quality standards.

🔑Key Points:
Breeder Seed
-A breeder’s seed is an offspring of a nucleus seed.
-A breeder is a person (qualified plant breeder) or organization that raises plants primary for breeding purposes.
-While the nucleus seed is genetically pure; the Breeder seeds are produced by mutual multiplication of three different lines which are denoted by A line, B line, and R line.
-A line is female, while B and R lines are male sterile.
-The seeds from offsprings with the best and desired quality are selected and certified as Breeder seeds.  
-Such seeds are protected by legal rights called Breeder’s rights.
-The Breeder seed is further multiplied into the foundation and certified seeds.
-In our country, Breeder seeds are produced Indian Council of Agricultural Research, National Seeds Corporation, States Farms Corporation, and agricultural universities in India.
Additional Information
-Foundation Seed
-Foundation seed is the progeny of Breeder seed or is produced from foundation seed, which can be clearly traced to Breeder seed.
-The foundation seed can even be produced from foundation seed during the production of Foundation Seed the minimum seed certification standard shall be the same for both foundation seed stage-I and II.
-The production of foundation seed stages I and II shall be supervised and approved by the certification agency and be so handled as to maintain specific genetic identity and genetic purity and shall be required to conform to certification standards specified for the crop/variety being certified.
-Certified Seed
-A certified seed shall be the progeny of foundation seed and its products shall be so handled as to maintain specific genetic identity and purity according to the standards prescribed for the crop being certified.
-Certified seed may be the progeny of certified seed provided this reproduction does not exceed three generations beyond the foundation seed stage-I.
-Registered Seed
-A registered seed shall be the progeny of the foundation seed that is so handled as to maintain its genetic identity and purity according to the standard specified for the particular crop being certified.
-A purple color certificate is issued for this category of seed.
