Q1. A wheat breeder wants a new variety that ripens early so a second crop can be sown the same season; which agronomic trait is she directly selecting for?
- A.A shorter duration from sowing to harvest
- B.More leaves to increase photosynthesis
- C.A taller stem to catch more sunlight
- D.Larger roots for deeper anchorage
Answer: A. A shorter duration from sowing to harvest
Fitting a second crop in the same season needs a fast-maturing variety. Short duration (fewer days from sowing to harvest) is the trait that allows multiple cropping.
Q2. On a windy plateau, a maize grower keeps losing tall plants that snap and fall flat before harvest; breeding for which characteristic would best solve this?
- A.Broader leaves for more shade
- B.A longer growing season
- C.Brighter flower colour
- D.Dwarf, sturdy stems resistant to lodging
Answer: D. Dwarf, sturdy stems resistant to lodging
Plants falling flat before harvest is lodging. A dwarf variety with a short, strong stem resists wind and does not lodge, protecting the yield.
Q3. A farmer in a region with very short, light rains needs a crop that survives on little water; which variety property should he look for?
- A.Tolerance to waterlogging
- B.Tallness
- C.Brighter grain colour
- D.Drought tolerance
Answer: D. Drought tolerance
Light, scanty rain means water scarcity. A drought-tolerant variety can complete its life cycle with little water, so it is the correct choice.
