Current status of groundnut improvement in uganda

Groundnut is the second most important legume in Uganda, cultivated on about 260,000 ha, but suffers from low yields averaging 800 kg/ha. Research has released 24 varieties to address various production constraints, but challenges remain due to agroecologies, land tenure, and market preferences. Current efforts focus on breeding for improved traits, employing advanced selection methods, and maintaining an active breeding pipeline to enhance crop performance and support smallholder farmers.

- 1. Current status of groundnut improvement in Uganda ABSTRACT: In Uganda, groundnut (Arachis hypogaea L) is the second most important legume after beans. Groundnut 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 resource-poor smallholder farmers. The yield gaps are attributed to a combination of biotic, abiotic, cultural and social-political factors. Since the 1920s, research has released 24 varieties, the most recent commercial ones being the Serenut 1-14 series. These varieties have helped to alleviate 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, leafminerresistance,confectionery,aflatoxintolerance,droughttolerance,earlytomediummaturingvarietieswithhighyieldinggroundnutrosettediseaseresistant backgrounds. A combined approach including Marker Assisted Selection, agroecological testing using Breeding Management Systems (BMS) software shows some promising perspectives and efficacy to resolve the current constraints challenging the crop performance. A recently developed regeneration protocol is also another opportunity to aid in introgressing additional traits across taxa. The bimodal rainfall pattern and active hybridization programme increases our breeding cycles.
