     The aim of present study was to determine the relationship between grain yield and important agricultural characteristics for six lines of rice and Shiroodi cultivar as control in rice research station (Tonekabon) in west of Mazandaran Province in 2015. The experiment was conducted in a randomized complete block design with three replicates. Analysis of variance showed that there was a significant difference between genotypes for all studied traits except flag leaf width, which indicates the appropriate variation among the studied genotypes. Results of mean comparison test showed that the highest and the lowest grain yield were belong to line No. 5 (7831.7 kg.ha-1) and No. 204 (6884.3 kg.ha-1) respectively. Results showed that there were positive and significant correlation between grain yield and number of tiller, 1000-grain weight, filled grain number and number of total grains per panicle. Using stepwise regression method showed that 1000-grain weight, filled grain number and number a tillers had the maximum effect on grain yield. Results of path analysis showed that 1000-grain weight an important and effective trait can be used for selection of high yielding rice lines in breeding programs.
