Performance of Andinet Soybean [Glycine max (L.) Merrill] Variety

Abstract

Several soybean genotypes that have been introduced in 2015 from the Institute of International Tropical Agriculture (IITA), Nigeria, by the Pawe Agricultural Research Center of the Ethiopian Institute of Agricultural Research were evaluated for yield and other desirable agronomic traits, aiming to identify genotypes that have better yields than the existing varieties cultivated in the country. The combined mean square of genotype plus genotype × environment interaction (GEI) analysis showed highly significant (P < 0.01) difference for grain yield among the tested genotypes. Genotype Tgx-1989-75F has showed best performance for grain yield, hundred seed weight, number of branches per plant and number of seed per pod based on the combined mean results. In addition, the genotype exceeded the standard check (Pawe-03) and local check (Gishama) varieties by 35.6% and 19.7%, respectively. And also, it has showed additional merits such as; resistance to frog eye leaf spot and tolerance to bacterial blight, brown leaf spot, red leaf blotch, and rust, and has been shown to be stable across test locations and seasons. Genotype Tgx-1989-75F has released as a variety with name “Andinet” and can be widely used for commercial farming in Pawe, Asosa, Bako, Sirinka, Areka, Jimma, Gonder, and similar areas, resulting in increased revenue for smallholder farmers.
