Eight bean lines

Eight bean lines with the perfect combination: drought resistance and high grain yield

NCB 280, NCB 226, SEN 56, SCR 2, SCR 16, SMC 141, RCB 593, and BFS 67, these are the technical names of the eight elite bean lines identified as parents to start new crossings improved for drought resistance at CIAT’s Bean Program. It has thus been reported in the recently published paper entitled Effective use of water and increased dry matter partitioned to grain contribute to yield of common bean improved for drought resistance. Resultado de dos años de trabajo…

Nigerian farmers beat high temperatures with dry-season groundnut varieties

Farmers in northern Nigeria are switching over to groundnut production in the hottest months of the year. From an initial six farmers cultivating the improved groundnut variety in the 2012 dry season, today there are over 5000 farmers in northern Nigeria involved in groundnut production. Unlike vegetables and fruits grown in the dry season, the groundnut produced during this period coincides with a peak in demand for groundnut seeds, so seed growers can tap a ready market. In addition, the…

Improving groundnut using near-isogenic lines for the first time

For the first time in groundnut crop, a Near-Isogenic Lines (NILs) evaluation trial of marker assisted backcrossing (MABC) derived lines, was constituted for national testing, under the All India Coordinated Research Project on Groundnut (AICRP-G). Constituting NIL trial under AICRP-G, is a key step towards the release of NILs for cultivation in target ecologies. AICRP-G coordinates the release of groundnut varieties in India through multi-location testing of groundnut lines across five groundnut growing agroecological zones of India. Thirteen elite NILs…

Working towards release of drought tolerant and disease resistant groundnut varieties in Nigeria

With the aim of proposing best bet groundnut varieties for release by the National Agricultural Seed Council, multi-location trials were conducted for the 2015 cropping season at Minjibir, Gumel, Zango and Zaria in northern Nigeria. The screening was for rosette tolerance, aflatoxin resistance, foliar fungal disease resistance and drought tolerance. Along with national partners, the ICRISAT groundnut breeding team has been working on developing varieties that are early maturing; climate resilient; have high pod, haulm and oil yields; tolerant to…

New common bean genotypes to confront drought

Drought affects 60% of the bean-producing regions, and is responsible for total crop failure in the worst-case scenario. But this fight is not lost as demonstrated by 13 new bean genotypes developed by scientists of CIAT’s Bean Program using interspecific crosses. The work was done in close collaboration with the Autonomous University of Barcelona (UAB), with the support of the Bill & Melinda Gates Foundation (BMGF) and CGIAR Research Program on Grain Legumes. This output resulted from several years of…

Climate-smart beans that can beat the heat

Responding to fears that bean production will take a big hit from global warming, CIAT scientists have identified about 30 “elite” lines showing tolerance to temperatures 4 degrees Centigrade above the crop’s normal “comfort zone.” Research on these beans, which is supported by the CGIAR Fund and documented in a recent CGIAR report, represents a major contribution to the CGIAR Research Programs on Grain Legumes and on Climate Change, Agriculture and Food Security. According to computer modeling conducted by Center…
