Field experiments were conducted two consecutive years, in order to investigate runner bean (Phaseolus coccineus L.) cultivated in pure crop system and in intercropping system. To achieve the desired aim, we set the following objectives: study of runner bean plant phenology, study of assimilating pigments content in the runner bean leaves, agro productivity study of runner bean crop, yield of runner bean crop, study of chemical composition of runner bean dry seeds. The studied experimental factor was the trellis system with six variants: (V1) - trellis, with double rows, on individual string, (V2) - trellis, with a single row, on individual string, (V3) - trellis, in a single row, on synthetic net (17 cm mesh), (V4) - intercropping with common maize plants, (V5) - intercropping with sunflower plants, (V6) - intercropping with Jerusalem artichoke plants. Runner bean yield ranged from 3,610 kg ha-1 (V2) to 1,684 kg ha-1 (V6) (first year) and from 3,170 kg ha-1 (V2) to 1,189 kg ha-1 (V6) (second year). Runner bean dry seeds contain: crude protein 22.65% (V6) - 25.47% (V3), crude fat 1.91% (V6) - 2.16% (V4), crude fibre 5.41% (V4) - 5.81% (V5) and nitrogen free extractive substances 62.11% (V3) - 64.92% (V4). The best variant of trellis for runner bean crop was the single row trellis system on individual string and the best intercropping system was intercropping with sunflower.

Runner bean (Phaseolus coccineus L.) offers a great potential as a grain legume in Africa. However, its productivity is low because no improved short-day varieties are available. The aim of this study was to evaluate advanced short-day runner bean lines for high grain yield, resistance to diseases and suitable for cultivation under tropical conditions. F6.8 recombinant inbred lines developed from crosses between local landraces and high yielding imported variety (White Emergo) were evaluated in 2013 and 2014 in a randomized complete block design with three replicates at Kabete (1860 m.a.s.l.) and Ol Joro-Orok (2300 m.a.s.l.) in Kenya. Four local runner bean landraces were used as checks. Analysis of variance showed that there were significant differences for days to flowering, response to diseases and grain yield among the evaluated lines. Improved lines flowered within 49 to 52 days in 2013 and 34 to 58 days in 2014.The improved lines flowered earlier at Kabete than Ol Joro-Orok and showed a higher degree of resistance (scores 1-3) to the major diseases rust, bean common mosaic virus (BCMV) and powdery mildew. The mean grain yield at Kabete was 4,426 kg ha-1 compared to 6,523 kg ha-1 at Ol Joro-Orok giving an average yield advantage of up to 67% compared with local short-day landraces. The results indicated that new high yielding short-day runner bean varieties with resistance to major diseases and tropical adaptation can be obtained from these lines.

Colletotrichum lindemuthianum, the causal pathogen of common bean (Phaseolus vulgaris) anthracnose, is highly variable. Therefore, understanding its race structure and identification of new sources of resistance is necessary for the development of varieties with durable resistance. The objectives of this study were (i) to characterize isolates of C. lindemuthianum collected from three major bean-growing regions in Zambia, and (ii) evaluate the CIAT Phaseolus core collection for resistance to C. lindemuthianum races 37, 73, and 566, and a blend of 20 races. Isolates collected from three major bean-growing districts in Zambia, namely Mporokoso, Mpika, and Mbala, were characterized as race 37, 73, and 566, respectively. A subset of the CIAT core collection comprised of 885 accessions of common bean, 13 accessions of scarlet runner bean (P. coccineus), and 11 accessions of year bean (P. dumosus) were evaluated for resistance to races 37, 73 and 566, and a blend of 20 races in a greenhouse at University of Zambia, Lusaka, Zambia. A total of 72%, 66%, 48% and 9% of P. vulgaris accessions evaluated were highly resistant to races 37, 73, 566 and a blend of 20 races, respectively. Also, accessions of P. coccineus and P. dumosus, highly resistant to races 37, 73 and 566, were identified. Only eight of the 331 P. vulgaris accessions were highly resistant to all three individual races (37, 73, and 566) and to a blend of 20 races. These eight accessions constitute a valuable breeding resource for developing varieties with durable resistance to C. lindemuthianum.
