Information on the combining ability, heterotic patterns and genetic diversity of maize (Zea mays L.) inbreds is crucial for the success of a hybrid program targeting the stress environments of West Africa (WA). Studies were conducted in 2011 at four locations in Nigeria to (i) determine the comb...

Los cruzamientos dialelos de 12 padres contrastantes en la toma y uso de fósforo se evaluaron en dos niveles de fósforo (4 y 15 ppm) usando un dise o experimental de alpha lattice con tres repeticiones. Se usó el dise o genético propuesto por Hallauer y Miranda. En bajo y alto fósforo se encontra...

The genetics of resistance to bean golden mosaic virus (BGMV) was studied in an 8×8 complete diallel cross of common bean, Phaseolus vulgaris L. The 28F1 hybrids, their reciprocals, and eight parents were artificially inoculated with BGMV under glasshouse conditions. Data were recorded and analyz...

Although cassava is a major food crop, its scientific breeding began only recently compared with other crops. Significant progress has been achieved, particularly in Asia where cassava is used mainly for industrial processes and no major biotic constraints affect its productivity. Cassava breedin...

Little is known about the inheritance of agronomic traits in cassava, or on the relative importance of epistasis for most crops. A group of 10 clones, adapted to the acid-soils environment was used as parents in a diallel study. Thirty genotypes were obtained from each F1 cross and cloned. Each c...

Genetic diversity that can be profitably exploited is a major desire of several maize (Zea mays L.) breeding programs. The objective of this study was to identify maize populations that could be used in reciprocal recurrent selection programs for combined resistance to two stem borers, Sesamia ca...
