Seed Technology MCQ Quiz in தமிழ் - Objective Question with Answer for Seed Technology - இலவச PDF ஐப் பதிவிறக்கவும்

The correct answer is Groundnut.

• It is the percentage of area sown out of total area of crop planted in the season by using certified/quality seeds other than the farm saved seed.
• It also denotes actual quality seed distributed to farmers to actual seed required for cultivation of crops.
• A better seed replacement rate shows a better utilization of the Certified / Quality Seeds.
• Thus, higher the Seed Replacement Ratio, higher is production as well as productivity and higher are chances of achieving nutritional security, food security and containing food price inflation.

• Seed replacement rate of some crops:

The correct answer is Breeder Seed.

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.

The correct answer is Golden yellow.

• ​Breeder seed comes with a golden yellow tag.
• Breeder seed: This is the seed of a new variety that has the highest purity and is produced, developed, controlled, and provided directly by breeders or their institutions for further multiplication.
• Breeder seed is the progeny of the nucleus seed.
• The breeder seed tag is golden yellow in color which is stitched to each bag.
• Relevant information and quality norms for the breeder seed are indicated in the tag attached to the seed bag

The correct answer is Genetic purity.

• Seed should be viable.
• Should have maximum genetic and physical purity.
• Should be compulsorily certified or truthful labelled.
• Should satisfy all quality norms.

The correct answer is Breeder Seed.

The correct answer is Heading Back.

Key Points 

• Heading Back: When the terminal portion of a branch or a shoot is removed partially, leaving the basal portion intact.

Additional Information 

• Pruning is the art and science of cutting away of a portion of a plant to improve its shape, influence its growth, flowering and fruitfulness, and improve the quality of the product.
• Pruning is done to divert a part of plat energy from one part to another.
• If a small portion of a terminal of a branch or shoot is removed, it is called ‘light pruning’.
• When a longer terminal portion is removed, it is called ‘medium pruning’, and
• If the pruning is severe it is called as Bulk or Heavy pruning.
• For good fruit production only judicious heading back or thinning out should be preferred.

Additional Information

• Dehorning refers to cutting away the main limbs or thick major branches.

• Staking is a practice to support the plants and keep the plants and fruits off the ground.
• Staking is especially practiced in the Tomato crop.
• Staking helps in maintaining the health of the plant.
• There are lesser chances of plants getting infested with pests and diseases by staking.

The correct answer is B. R. Barwale.

• Badrinarayan Ramulal Barwale is known as the father of Indian seed technology.
• He is known for his pioneering work on producing cheaper and better quality seeds in the Marathwada region of Maharashtra.
• He started the Maharashtra Hybrid Seeds Company, also known as Mahyco, where he cultivated the higher efficiency seeds and began selling them to farmers at an affordable price
• Barwale was awarded the 12^th World Food Prize in 1998 for his work in providing affordable, high-yield seed varieties and agronomic training to farmers across India.
• He died on 24 July 2017 in Mumbai.

The correct answer is the Tetrazolium test.

• The tetrazolium test was given by Lakon in 1942.
• It is a quick, easy, and popular method of testing seed viability.
• Also known as biological test.
• Seeds are soaked in 0.5 - 2% solution of 2, 3, 5 triphenyl tetrazolium chloride.
• The viable or living seeds take bright red coloration and the color becomes more intense in the embryo.
• This test should not be applied to any sample containing dry germinated seeds.
