Extract

The problem of drought presents a challenge to plant breeders as breeding is a major method by which yield improvement can be obtained in drought-prone areas. The plant responses to drought and the nature of drought resistance have received the attention of several workers (Kozlowski, 1968; Kramer, 1969; Levitt, 1972). There are reports in the literature which show that yield and drought resistance are controlled by separate genetic entities. Breeding thus requires identification of definite drought resistance attributes and their transfer to high-yielding and agronomically acceptable cultivars.
