Recent Genetic, Breeding and Biotechnology Techniques for Improving Livestock Production

Breeding and biotechnology for improving the nutritional quality of strawberry

Traditional breeding is based on the identification of the most suitable genetic resources from either cultivated or wild germplasm. Starting from wild germplasm, progeny from strawberry crosses with F. virginiana glauca as a common parent have shown significant increases in fruit quality and nutritional features. This confirms the use of the wild species to improve several characteristics of c...

Development of breeding and fingerling production techniques for endangered long-whiskered catfish Sperata aor in captivity

An experiment was undertaken to develop a suitable seed production technique for Sperata aor in captivity. Naturally produced fry of aor was reared at different densities in nine nursery ponds 0.012 ha in size with an average depth of 0.8 m each. Three stocking densities tested, each of which was triplicated. Fry of aor stocked at 100,000/ha was designated as treatment-1 (T1), 150,000/ha as tre...
