Identifying superior feed barley genotypes using GGE biplot for diverse environments in India

Published on

Barley (Hordeum vulgare L.) is an important feed purpose
cereal grown under diverse production conditions and harsh
environments. The present investigation was carried out
to study performance of advanced breeding lines and
identify superior genotypes of feed barley using multienvironment trial data from All India Coordinated Wheat
and Barley Improvement Programme (AICW&BIP). Ninety
three experimental genotypes and five released cultivars
were tested across eleven locations during four years. Grain
yield and other agronomic traits were analyzed. Stability
and genotype superiority for grain yield and other traits
were determined using genotype and genotype ×
environment (GGE) biplot analysis. The result showed that
environment and genotype contributed 32.9 to 67.4% and
4.7 to 20.4% of the total variation, respectively. The genotype
× environment interaction contributed 27 to 44% of total
variation. The experimental genotypes showed arrays of
variation for grain yield in each year, with mean values
ranging from 2.12 to 5.36 t/ha. Twelve experimental
genotypes were identified, which were either superior or
equal performance to the best check based on their high
yield and stability across environments. The locations
Varanasi, Kanpur, Vijapur and Durgapura discriminated the
genotypes more than other sites for grain yield and
agronomic traits. The findings provided valuable
information on wide adaptation of feed barley genotypes,
which could be useful for barley improvement programmes
