Additive, dominant, and epistatic effects for maize grain yield in acid and non-acid soils

Autor: Ceballos, H. Pandey, S. Narro Leon, LA Pérez Velásquez, Juan Carlos

Acid soils severely reduce maize (Zea mays L.) yield in the tropics. Breeding for tolerance to soil acidity provides a permanent, environmentally friendly, and inexpensive solution to the problem. This study was carried out to determine the relative importance of additive, dominant, and epistatic...

Cassava breeding II: phenotypic correlations through the different stages of selection

Autor: Barandica, Orlando Joaqui Lenis, Jorge I. Calle, Fernando Morante, Nelson Pérez, Juan C. Hershey, Clair H. Ceballos, H.

Breeding cassava relies on a phenotypic recurrent selection that takes advantage of the vegetative propagation of this crop. Successive stages of selection (single row trial- SRT; preliminary yield trial – PYT; advanced yield trial – AYT; and uniform yield trials UYT), gradually reduce the number...

High-throughput phenotyping and improvements in breeding cassava for increased carotenoids in the roots

Autor: Belalcázar, John Dufour, D.L. Andersson, Meike S. Pizarro, Mónica Luna, Jorge Londoño, Luis Fernando Morante, Nelson Jaramillo Valencia, Angélica M. Pino, Lizbeth Becerra López Lavelle, Luis Augusto Davrieux, Fabrice Talsma, Elise F. Ceballos, H.

Past research developed reliable equations to base selections for high β-carotene on near-infrared spectroscopy (NIR) predictions (100 genotypes d−1) rather than with high-performance liquid chromatography (HPLC) (<10 samples d−1). During recent harvest, CIAT made selections based on NIR predicti...

Autor: Njoku, DN Vernon, G Egesi, Chiedozie N. Asante, I.K. Offei, SK Okogbenin, Emmanuel Kulakow, P.A. Eke-Okoro, O.N. Ceballos, H.

This review presents an overview of the importance, constraints, and prospects on different aspects of cassava (Manihot esculenta crantz) breeding for enhanced micronutrient level, including carotenoids (precursors for provitamin-A) and especially beta-carotene. Early cassava-breeding efforts con...

Autor: Pérez, J.C. Lenis, Jorge I. Calle, F Morante, N Sánchez, T. Debouck, Daniel G. Ceballos, H.

Cassava roots are the most important commercial product from this crop. Roots have two major components: the starchy parenchyma and the peel with higher amount of fibre and cyanogenic glucosides. In this study, a sample of 64 clones grown in replicated trials in five locations were evaluated for ...

Cassava Breeding I: The value of breeding value

Autor: Ceballos, H. Pérez, Juan C. Barandica, Orlando Joaqui Lenis, Jorge I. Morante, Nelson Calle, Fernando Pino, Lizbeth Hershey, Clair H.

Breeding cassava relies on several selection stages (single row trial-SRT; preliminary; advanced; and uniform yield trials—UYT). This study uses data from 14 years of evaluations. From more than 20,000 genotypes initially evaluated only 114 reached the last stage. The objective was to assess how ...
