Abstract

The majority of the population in Burundi grow and consume maize. Inhabitants of high altitude areas also produce peas. The objective of this project is to continue research on high yield and disease resistant varieties of these crops for maximum production under growing conditions. A further objective is to train researchers to continue studies on crop varieties and cultivation practices.

Post-Project Summary

In trials and on-farm research, over 200 varieties of maize from CIMMYT (Centro Internacional de Majoramiento de Maiz y Trigo) and IITA (International Institute of Tropical Agriculture) were introduced and evaluated along with local maize lines at seven sites in three climatic zones. PHA (population haute altitude) and Pool 9 were identified as improved maize populations, and were popular among farmers. Sources of streak disease resistance (SR) were evaluated and gene transfers were achieved in the superior varieties Pool 9, PHA, and A cross 7843. In medium and high altitudes PHA.SR was developed as a local streak resistant variety by using the half-sib family selection method. Other results showed that using peat, limestone, and phosphate increased maize yields in high and medium altitudes. In 45 farmers' trials maize was intercropped with rice, cowpeas, or beans, and produced promising results. Numerous pea varieties from England, Ethiopia, Syria, the Andes, North America, and Europe were introduced and evaluated. Results indicated the introductions were not well adapted to Burundian conditions, and local pea germ plasm had more promise of achieving improved yield and disease resistance.
