STABLE GENOTYPES OF RICE FOR SODIC SOILS

Published on

Stability parameters based on 24 promising rice genotypes were estimated under
sodic soil for various traits. The genotypes were severely influenced by the varying
levels of sodicity and the G x E interaction was highly significant for all the
characters indicating the differential response of the rice genotypes in different sodic
environments. Both linear and non- linear components of variation were significant
for day. to 50% flowering, height and grain yield, while only non-linear component
of variation was found to be significant for ear bearing tillers. The salt tolerant
rice variety CSR 18 appeared to be the most stable and ideally adaptable cultivar
in all the varying stress enviomments. Other rice genotypes like CSR 11 and
CSR 10 proved to be the best adaptable genotypes in highly deteriorated sodie
soils. Hence these genotypes could judiciously be used in breeding programme for
improving the productivity of rice in sodie soils.
