Agronomic description of new improved climbing bean varieties

Abstract

Eleven genotypes including one local check (Kanyamunyu) were grown In a trial at Kachwekano and Namulonge in
1996a, 1996b and 1997b. The trial was arranged in a randomized complete block design rCJ)Iicated three times.
Staking was carried out at v• stage and description was made for the following agronomic characters: disease
infection, days to flowering, days to maturity, seed yield, seed size and cooking time. Genotypes U mubano, Ngwinurare,
RWV 296 and Vuninkingi were identified for release as new bean cultivars in Uganda. Both genotypes are climbers
and mature within 81-115 days. Depending on the growing conditions, the seed yield was 700 to 3800 kg/ha. Cooking
time varied from 40-70 minutes depending on variety. Varieties with most preffered seed characteristics were
Ngwinurarc and RWV 296. Variety Ngwinurare was repor1ed by lDEA project to posses attributes suitable for export
market Varieties Umubano and Vuninkingi performed well in both low and high altitude environments.
