Cowpea is the most important product in African dryland agriculture. Its protein-rich grains are the main product of the crop, which are commonly eaten in different forms by rural and urban peoples. African farmers growing cowpea in their fields often harvest low yields because many biotic and ab...

Several primary tetraploids with desirable attributes have been selected by Musa breeding programs. Diploid parental stocks have become available for further genetic improvement of the Musa genome. Hence, new genome manipulations should be tested before they become routine in breeding programs. T...

Autor: Ortiz, R. Vuylsteke, D.R.

Plantain and banana (Musa spp. L.) polyploid hybrids have been obtained after interspecific hybridisation and ploidy manipulations (i.e., interploidy crosses). The identification of promising hybrids for cultivar release requires their field testing to assess agronomic performance. The potential ...

Accurate assessments of genetic gains ensuing from plant breeding for the most important agronomic characteristics in Nordic spring barley (Hordeum vulgare L.) are not available. Hence this research was aimed to determine the rate of genetic improvement in the Nordic barley breeding pool. This st...

Sorghum (Sorghum bicolor(L.) Moench) is the fifth important cereal crop after wheat (Triticum aestivumL.), maize (Zea maysL.), rice (Oryza sativaL.), and barley (Hordeum vulgareL.) in the world. It is cultivated in about 46 million ha with a total production of 62 million t (FAO 1998). Asia and A...

Scientific strategies for crop improvement ensue from genetic knowledge gain from the relevant breeding populations. Few genetic studies were undertaken in Musa before the 1990s, despite the importance of the crop in human diet in the tropics. It was believed that genetic studies of most cultivat...

The triploid plantain landrace Obino l Ewai (Musa spp., AAB genome) has been crossed with a wild diploid banana (M. acuminata subsp. burmannica var. Calcutta 4 , AA genome) to generate full-sib diploid and tetraploid hybrids combining good agronomic performance and disease resistance. Microsatell...
