Use of AMMI and GGE Analyses to Identify Stable and Resistant Soyabean (Glycine max L. Merrill) Genotypes Infected with Cucumber mosaic virus | Chapter 11 | New Perspectives in Agriculture and Crop Science Vol. 1
Soyabean is an important source of
protein for millions of people in developing countries. However, infection by
Cucumber mosaic virus (CMV) causes devastating losses. Cultivation of resistant
varieties has been identified as the best management strategy in many crops.
The present study was, therefore, conducted to identify soyabean genotypes with
high stability for growth and seed weight under CMV and disease-free
conditions. Thus, eight soyabean genotypes were evaluated as CMV-infected and
uninfected, using completely randomised design replicated five times and set up
in the screenhouse at the School of Agriculture and Agricultural Technology,
Federal University of Minna, (lat.9°40֬ N;long
6°30֬ E at an altitude of 220
m.a.s.l), Nigeria in 2018. Soyabean seedlings were
infected with the virus by sap transmission at 10 days after sowing (DAS).
Additive Main Effects and Multiplicative (AMMI) analyses of the evaluated
parameters for growth and seed weight of the test genotypes showed that
environments’ effects -infected and uninfected- were significant (p<0.05).
They accounted for 100% Genotype × Environment (G×E) interaction. Disease-free
soyabean plants enhanced significantly higher growth and seed weight than the
CMV-infected plants. The AMMI and Genotype main effects (G) plus Genotype×Environment (GGE) analyses showed that TGX 1993-4FN was the genotype
with the greatest stability for leaf diameter, leaf length, number of leaves
per plant, number of days to flowering and seed weight. It is recommended that,
the soyabean genotype TGX 1993-4FN, can be exploited for breeding purposes and
strategies that will prevent CMV infection in soyabean fields should so be
adopted by farmers pending the development of new soyabean varieties
incorporated with durable resistant traits for CMV.
