GENOTYPE X ENVIRONMENT INTERACTION FOR GRAIN YIELD IN LOWLAND RICE CULTlVARS

Published on

Genotype x environment interaction was studied for grain yield in 24 genotypes of
lowland rice under five different environments in eastern India. Significant genotype
(G) and environment (E) interaction was observed. Both linear and non- linear
components of G x E interaction were significant, linear component being the
predominant. On the basis of stability parameters two genotypes, RAU 79-2-14 and
RAU 617-59-14-1 were found to be most stable with high grain yield over different
environments. The selection from Raipur (lET6286/Bd.83)-29 was identified as suitable
genotype for favourable environments.
