| Abstract | ||
| A field experiment was carried out at field of Gamass during 2010 groaning season to study path coefficient analysis for many rice genotypes to determinate the characters, which correlated with grain yield of rice. The design was RCBD in three replications. The statistical analysis showed higher positive phenotypic correlation between number of days from sowing to maturity and grain yield (0.981). Path analysis showed that number of days from sowing to maturity was gone higher positive direct effect (0.935) on grouch yield and indirect effect via number of days from sowing of 50% an thesis, therefore it could be used as a selective index for improving new strains programs of rice. | ||
