Question

How can disease resistance be incorporated in crops?

• A. By crossing disease resistant wild relative with the crop variety
• B. By domestication of the crops
• C. By removing the R genes from the crops
• D. None of the above

Answer 1

The correct option is A By crossing disease resistant wild relative with the crop variety

The wild varieties of crops retain their disease resistance capability. If we want to introduce disease resistance in our crop varieties, we cross-pollinate the domesticated high yielding varieties with the disease resistant wild relatives, this confers the progenies with resistance against many of the pathogens attacking the crops.
