An on-farm study was carried out under rain-fed condition in
2003 - 2004 and 2004 - 2005 growing seasons in five sites
namely Ntchenachena and Ngong’a in Rumphi district, Chipuka
in Ntchisi district, Thondwe and Matapwata in Zomba and
Thyolo districts respectively representing three bean
agro-ecological zones of Malawi. Seven dwarf bean entries;
DC 96-95, PC 490-D8, BCMV-B2, SDDT-54-C5, APN 130, F6BC (19)
and DOR 715 were evaluated for their yield stability across
sites and two seasons under Researcher Designed Farmer
Managed (RDFM) system. Yield stability of the entries across
years varied significantly. Entries SDDT-54-C5, PC490-D8 and
DOR 715 were stable across all sites and between the two
seasons.
DOR 715 was also high yielding entry in Thondwe and
Ntchenachena sites followed by BCMV B2 though the latter was
unstable. Among sites, Thondwe was the best because yields
of most of the bean entries were stable at this site.
