Abstract

The associations among sodic tolerant physiological traits and their direct and indirect influence on yield of rice were investigated. For this purpose 45 hybrids and their nine parents were  tested in randomised block design. Grain yield per plant had significant positive correlation with  sodic tolerant traits viz., productive tillers per plant, filled grains per panicle, spikelet fertility, harvest, total chlorophyll, chlorophyll a/b ratio, chlorophyll stability index, catalase and peroxidase activity. Hence, improvement in any one of the sodicity tolerant physiological characters might improve the sodicity tolerance as well as yield in rice.  The days to 50 % flowering had non-significant positive association with grain yield hence making any improvement on this character would not highly influence on sodicity tolerance in rice. The sodicity tolerant traits viz., productive tillers per plant, filled grains per panicle, spikelet fertility, harvest index, total chlorophyll, chlorophyll stability index, peroxidase and catalase activity were mutually correlated with each other.

Keywords
