Strategies for enhancement in food production practice · Hard

Option B (A-low, B-seed) is correct because germplasm collections are usually maintained at a low temperature in the form of seeds.

Option D (I, II and III) is correct because mutation breeding involves inducing mutations, screening for resistance, and selecting desirable plants for multiplication.

Option C (If Assertion is true but Reason is false) is correct because hydrated artificial seeds must be planted soon after production, but this is due to their vulnerability to desiccation and microbial contamination, not moisture absorption from the air.

Option B (Laminar air flow chamber) is correct because it provides a sterile environment to prevent contamination during inoculation of explants.

Option B (Antheraea mylitta) is correct because Tasar silk is specifically obtained from the Antheraea mylitta silkworm species.

Option D (Both 2. and 3.) is correct because both Antheraea paphia and Antheraea assama are species of silkworms found in India.

Option D (Pomato) is correct because "Pomato" is the common name for a plant produced by grafting or somatic hybridization between a tomato and a potato.

Option D (Stem sawfly) is correct because solid stem in wheat provides resistance against the stem sawfly.

Option C (Quantitative trait mutations) is correct because mutations in quantitative traits, such as plant height and flowering time, contributed significantly to the Green Revolution in wheat.

Option B (If both Assertion and Reason are true but Reason is not the correct explanation of Assertion) is correct because while both statements are true, protoplast fusion isn't the primary advantage of tissue culture.
