Question

Dee-geo-woo-gen is a dwarfing gene of
(a)Rice
(b)Barley
(c)Oat
(d)Maize

Answer 1

IR8 was a crossbred variety developed by the crossing of a variety with a high production rate, Peta from Indonesia, and a dwarf variety Dee-geo-woo-gen from Taiwan in 1962 by the IRRI research team.

Complete answer:
Dee-geo-woo-gen is a dwarfing gene of rice (mutant gene) that is differentiated by dwarf plant features. The plants will be half the size of the tall conventional species along with strong and stiff leaves to guarantee complete revelation to sunlight, light insensitivity, and absence of dormancy of the seeds.

Additional Information: -The seed of the grass variety, Oryza glaberrima commonly known as African rice or Oryza sativa, common name Asian rice is called as rice.
-Rice is a cereal grain and is the most commonly used staple food for a major portion of the human population of the world, mostly in Asian and African countries.
-It is also an agricultural crop which is the third-highest produced crop in the world with an average of 741.5 million tonnes, after the top two crops, sugarcane with 1.10 billion tonnes and maize of 1.1 billion tonnes of production.
So, the correct answer is Rice.

Note: -Taichung Native-1 is the first semi-dwarf rice variety that is produced by a cross among Dee-geo-woo-gen and tall species that have properties like drought-resistant and disease resistance.
-Rice is a monocot that is normally cultivated as an annual plant, but in tropical regions, it is grown as a perennial and can be cultivated for 25-30 years.
-Weeds, pathogenic organisms, insects, small rodents, and several birds are common pests that threaten rice cultivation. The overuse of fertilizers and pesticides along with climatic changes affects rice cultivation.
