Maize hybrids have been developed for higher amount of

  1. Lysine

  2. Leucine

  3. Methionine

  4. Cysteine
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Maize hybrids with higher lysine content were developed to improve the protein in corn.
  • This hybrid maize provides substantially higher levels of two essential amino acids - Lysine and tryptophan.
  • So the correct answer is 'Lysine'

  3. Gram

  4. Sugarcane
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  • Wheat is a  cereal grain which is a worldwide staple food. Wheat is an important source of carbohydrates and has a protein content of about 13%, which is relatively high compared to other major cereals.
  • RR-21 (Sonalika) is a high yielding variety of wheat which is an early maturing single dwarf wheat with wide adaptation and good attractive amber grains. The variety is very suitable for late sowings. It is resistant to rusts.
  • Other varieties of wheat are kalyansona and girija.
So, the correct answer is 'Wheat'

Which of the following is not a genetically modified crop plant? 

  1. Golden rice

  2. Basmati rice

  3. Bt-corn

  4. Flavr savr tomato
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Golden rice is produced by genetic engineering to biosynthesize beta-carotene. Genetically modified corn is a genetically modified crop. Maize strains have been genetically engineered to acquired traits, including resistance to pests and to herbicides. Flavr Savr a genetically modified tomato was the first commercially grown genetically engineered food for human consumption.  Basmati rice GM crops have increased the reliance of farmers on herbicides and leading to new weed problems as well as to many legal problems.  

So the correct answer is'Basmati rice'.
