BIOXII09: STRATEGIES FOR ENHANCEMENT IN FOOD PRODUCTION

343564 Which one of the following pairs is correctly matched?

1 Hybrid vigour : Lost due to inbreeding depression
2 Inbreeding: Cross pollination
3 Male sterility: Self pollination
4 Jaya and Ratna : Sugarcane
BIOXII09: STRATEGIES FOR ENHANCEMENT IN FOOD PRODUCTION

343565 In high yielding hybrid crop varieties, to exploit hybrid vigour, the farmers need to purchase fresh hybrid seed every year because

1 They are not allowed to grow their own seeds
2 The hybrid vigour is lost due to inbreeding depression
3 Plants with hybrid vigour do not produce seeds
4 It is cheaper to purchase fresh seed
