Registration of ‘Babile-4’ and ‘Babile-5’ Groundnut Varieties
Background: In Ethiopia, groundnut (Arachis hypogaea) is widely grown for food, cash income and animal feed. Aspergillus species infections and aflatoxin contamination in groundnut along the production chains have become the major problems in the country. Over thirty groundnut varieties have been released in Ethiopia. However, none of them were bred or evaluated for resistance against Aspergillus flavus and aflatoxin contamination.
Objectives: The objectives of this study were to identify groundnut genotypes with resistance to Aspergillus flavus and aflatoxin contamination, and to identify high yielding genotypes with desirable agronomic traits.
Materials and Methods: Two independent experiments (experiment-I and experiment-II) were conducted at Pawe, Babile and Werer during the 2015 and 2016 main cropping seasons. Sixteen and 19 groundnut genotypes, including standard checks in experiment-I and experiment-II, respectively, were laid out as a randomized complete block design with three replications.
Results: Genotypes with accessions code ICGV 95469 and ICG 67 x BIGSEED were released with local names ‘Babile-4’ and ‘Babile-5’, respectively to be cultivated in Ethiopia. Babile-4 and Babil-5 had significantly higher average seed yields of 1.86 t ha–1 and 2.12 t ha–1 and yield advantages of 41% and 16% over the standard checks, Were-961 and BaHa-Jidu in that order. Besides, Babile 4 and Babile 5 were stable in seed yield across the test environments. Furthermore, Babile-4 was found to be resistant to Aspergillus flavus while
Babile-5 has good seed features (large seed size, preferable seed color and ease of blanching) for confectionery purposes. Thus, the National Variety Release Committee evaluated these two varieties through commonly used procedures and approved them for release in 2019.
Conclusion: Two groundnut varieties, Babile-4 and Babile-5, have been approved for release and recommended for production in Babile, Pawe, Werer and other agro-ecologically similar areas in Ethiopia.
