Answer:
little available genetic variation
Potential for exploiting hybrid vigor in wheat is limited wheat is predominantly outcrossing
Explanation:
Pure lines are varieties with little genetic variation. Pure lines are generated from crops that have undergone selection to the point of uniformity this is done to reduce variation that may occur genetically and to get varieties that are the same genetically.
Pure lines are they are the same genetically with no segregating genes. variation or changes in pure lines is mostly associated with the environment. wheat is an outcrossing crop generating a pure line will help have good vigour as selection would have been done to generate varieties that are strong and high yielding.
