Using AMMI approach to delineate genotype by environment interaction and stability of barley (Hordeum vulgare L.) genotypes under northern Indian Shivalik hill conditions

Published on

Genotype by environment interaction (GEI) of 18 barley
varieties was assessed during two successive
rabi crop
seasons so as to identify high yielding and stable barley
varieties. AMMI analysis showed that genotypes (G),
environment (E) and GEI accounted for 1672.35, 78.25 and
20.51 of total variance, respectively. Partitioning of sum of
squares due to GEI revealed significance of interaction
principal component axis IPCA1 only On the basis of AMMI
biplot analysis DWRB 137 (41.03qha
–1), RD 2715
(32.54qha
–1), BH 902 (37.53qha–1) and RD 2907 (33.29qha–1)
exhibited grain yield superiority of 64.45, 30.42, 50.42 and
33.42 per cent, respectively over farmers’ recycled variety
(24.43qha
–1).
