Abstract

The experimental material used in the present study included 36 genotypes of rice. The material was obtained from the plant breeding farm, Faculty of Agriculture, Annamalai University, Annamalainager, during June-Sept., 2004. The experimental field was under saline condition with pH of 7.9 and EC of 4.8 dSm-1. These genotypes were grown with all the recommended cultural practices. The experiment was laid out in Randomized Block Design, consisting of three replications. The crop was spaced at row-to-row 20 cm and plant-to-plant 15 cm. On the basis of heritability estimates and expected genetic advance as percent of mean for different characters studied in the present study, selection criteria based on number of branches/panicle, straw yield/plant, number of fertile florets/plant, total biological yield/plant and grain yield/plant would be useful in further improvement of rice
