Introduction Of Anthephora Species To The Tropical Rain Forest: Implications For Grazing Propagation And Breeding Of The Species

Three species of Anthephora of derived savanna origin were introduced into the tropical rain forest environment and their adaptability to the region was determined through morphological and seed yield studies. The three species, A. ampulacea (file grass), A. nigritana and an induced autotetraploid of A. ampulaca designated as A. ampulacea (4x) maintained, to a large extent their biological description, but a more luxuriant growth was recorded compared to reports from the areas of origin. Leaf measurements (length and with), leaf and tiller numbers were greater than twice the values reported in literature at 50% heading. This implies that the species exhibit phenoplasticity. Seed production was however low in all three species and the seeds when produced were to a large extent sterile. Grasses of the genus Anthephora can therefore be used as both wet and dry season pasture in southern Nigeria. The problem of sterile seed can be overcome by breeding the species for seed production in the savanna region of the country where the grass is indigenous and seed production is not hampered, while growing it in the rain forest region purely for pasture and hay-making.

Key words: Breeding, Anthephora ampulaca 2x, A. nigritana 4x, A. ampulacea 4x, phenoplastic, pasture.
