Influence of Increased Salt Stress on Correlations between Different Attributes of Rice

Abstract

Twenty four rice genotypes were grown under salt stress conditions, in the artificially salinized cemented field basins. The correlations between different attributes were computed separately for each salt stress. Different inevitable correlations were observed, but increased salt stress affected the magnitude of these correlations. The attributes of number of grains per panicle, total florets per panicle and panicle fertility showed very highly significant positive correlations with yeild per plant under the highest salt stress. Such attributes may be utilized as the selection indices for salt tolerance.
