Strategies for Enhancement in Food Production Test - 12

The entire collections of plants, seeds, plant parts having all diverse alleles for all the genes of a crop is called germplasm collections. Different parts of plants are kept at different temperature.

The capacity to generate a whole plant form any cell or ex-plant is called totipotency. Plants are totipotent and from small part of plant new whole plant can be grown.

The differentiated mass of cells is called callus. During tissue culture, callus is formed when small part of plant is kept in nutrient medium. Callus cells divide rapidly.

Polyploidy is a condition in which multiple sets of chromosome is present in same cell in place of usual two sets (diploid). Bread wheat is generally hexaploid.

Wheat plants are generally not infected by leaf and stripe rust. Common disease of wheat includes rust and smut disease. Wheat plants are not develop resistance for leaf and stripe rust.

National Seed Corporation is responsible for maintaining purity of seeds of crop plants. This organization checks the purity of gene from pathogens as well as harmful effect of the contents present in it.

Lysine is a type of amino acids present in the proteins. Maize variety Shakti is rich in lysine amino acids.

If a person get food that do not contain all micronutrient, protein and vitamins in required amount as per age, sex, working condition, this condition is called hidden hunger.

Gene banks are part of ex situ conservation of plants or plant parts. In ex situ conservation, plants parts are maintained in laboratory condition. In in situ conservation, plants are kept in natural condition with protection.

Cultivated plants are mostly allopolyploids that contain multiple sets of genetic material in their cells. Bread wheat is generally hexaploid. Allopolyploids occurs due to faulty karyokinesis.
