abstract: In Uganda, groundnut (Arachis hypogaea L) is the second most
important legume after beans. Groundnuts is cultivated on
nearly 260,000 ha, representing 24.6% of the total arable
land. On-farm pod yields are low, averaging 800 kg/ha of dry
pods, compared to on-station potential yields of 3,000kg/ha.
Sales from current production could potentially generate $344
million to the producers who are largely small-scale farmers.
The yield gaps are attributed to a combination of biotic, abiotic,
cultural and political factors. Since the 1920s, research efforts
have released 24 varieties, the most recent commercial varieties
being the Serenut 1-14 series. These varieties have overcome
some of the mentioned production constraints. However,
varied growing agroecologies, land tenure systems, diverse
market preferences, and emerging stresses call for continuous
research. Current research agenda includes breeding for high
oleic, leafminer resistance, confectionery, aflatoxin tolerance,
drought tolerance, early to medium maturing varieties, high
yielding, and rosette disease resistant varieties. We have initiated
Marker Assisted Selection for high oleic breeding and
adopted BMS for Digitalization of data capture, management,
analyses and storage. Recently developed regeneration protocol
will aid in introgressing additional traits across taxa. The
bimodal rainfall pattern and active hybridization programme
increases our breeding cycles. To date, the groundnut breeding
program has an active breeding pipeline frequently releasing
varieties and lines which have already been shared with National
Programs across Africa, Haiti and the USA with many
additional National Programs making requests. We have strong
partnerships in Research and Development among the African
Countries, USAID, ICRISAT, and BMGF.
