Genomics project on groundnut aflatoxin research launched

            To identify the genomic regions and genes associated with aflatoxin resistance in groundnut using a combination of genomics approaches, a new research project was launched. Aflatoxins are among the most potent mycotoxins, carcinogenic and teratogenic compounds.  Groundnut and maize are the most susceptible to aflatoxin contamination. One of the main objectives of the new project is to validate the identified genes and develop diagnostic markers so that they can be deployed in molecular breeding…

Seed fairs to promote climate resilient varieties in West Africa

Aiming to increase awareness of farmers on climate-resilient varieties of groundnut and maize and create opportunities to network with diverse players along the value chain, two seed fair programs were organized at Sikasso and Kayes regions of Mali recently. The objectives were to: Strengthen and stimulate linkages and information sharing among farmers on high yielding, drought and disease tolerant varieties; Distribute small package of seeds of the improved varieties to farmers; Create awareness of alternative seed sources and varieties; Create…

Global team cracks ancestor genome of groundnut

A scientific breakthrough on the DNA sequencing of groundnut promises the development of improved groundnut varieties with enhanced traits such as increased pod and oil yield; drought and heat tolerance and greater disease resistance. Other significant traits this could help develop include aflatoxin-free, nutrition-rich and allergen-free varieties. The breakthrough also provides insights into geocarpy – a unique reproductive process of the groundnut, oil biosynthesis and allergens. A team of 51 scientists from 9 institutes from China, India, USA and Australia,…

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…

Small farmers don’t give up on Pendo groundnut in Tanzania

Blog by Emmanuel Monyo. This blog first appeared on ICRISAT’s Agri-buzz Annual groundnut production in Tanzania doubled from 340,770 tons in 2008 to 810,000 tons in 2012, and smallholder farmers as part of the Tropical Legumes II project largely contributed to this growth. Smallholder farmers hold the key to agriculture all over the world, and it is no different in Tanzania. Here, the Jipe Moyo group (which means ‘don’t give up’) formed in 2011 as a savings and loans group,…

Aflatoxin detection gets a boost in Nigeria: Laboratories installed at two NARS centers

Creating awareness about aflatoxin, its prevention and detection is a priority target in the groundnut and sorghum value chain programme of the Federal Government of Nigeria. In a step towards strengthening this, ICRISAT helped set up two aflatoxin detection and quantification laboratories at the NARS centers in Nigeria. The two laboratories set up at the Institute for Agricultural Research (IAR)/Ahmadu Bello University (ABU) Zaria, and the Federal University of Agriculture (FUAM), Makurdi, are expected to serve as aflatoxin detection centers…

Devi variety popular with groundnut seed farmers in Odisha, India

Farmers are taking up seed production of Devi (ICGV 91114), the early-maturing and drought tolerant variety of groundnut in a big way. The foundation seed and certified seed production of this variety was taken up in 564 ha during the 2015-16 postrainy season. The seed production program involved over 1000 farmers across four districts (Nuapada, Bolangir, Kalahandi and Ganjam). The farmers get an additional income of Rs 8000 (US$119) per ha, considering an average yield of 800 kg per ha.…

Technologies developed in Malawi reduce drudgery and labor in groundnut

The most labor intensive operations in groundnut production – harvesting, stripping and shelling – have now been mechanized to ease the drudgery and labor of smallholder farmers. Through a consortium which included Compatible Technology International (CTI), Minnesota; Department of Agriculture Research Services (DARS), Malawi; and ICRISAT, the equipment that can lift (harvest), strip (remove pods from plants) and shell groundnuts faster and more efficiently than manual processes, was designed and adapted. The lifter can harvest four times faster than manual…

Genome code of cultivated groundnut cracked

In a scientific breakthrough that promises accelerated gene discovery and development of improved cultivars, researchers have completed high quality sequencing of the ancestral genomes of groundnut. This will lead to better groundnut varieties with enhanced pod and oil yield, greater resistance to diseases, tolerance to drought and heat, and better oil quality. The groundnut grown today is the result of hybridization between two wild species, Arachis duranensis (V14167, A-genome ancestor) and A. ipaensis (K30076, B-genome ancestor). The hybrid was cultivated…

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…
