Character Association

An exploratory research work was conducted to study the character association and their direct and indirect effects on grain yield in three bacterial blight resistance genes introgressed segregating populations (F2) in rice. Data for yield and five other traits which were component of yield were recorded in 449 F2 individuals in all three crosses. Thousand grain weight was highly correlated with single plant yield in (r=0.95**, p<0.01) CB 174 R ? IRBB 60> (r=0.48**, p<0.01) CB 87 R ? IRBB 60> (r=0.44**, p<0.01) TNAU CMS 2B ? IRBB 60. Thousand grain weight was exhibited important yield determining component for CB 174 R ? IRBB 60 (0.92) and CB 87 R ? IRBB 60 (0.45), and panicle length for (0.39) TNAU CMS 2B ? IRBB 60 by direct effect. The genetic information derived from our study could be useful to select potential segregating individual among the F2 population for future rice breeding program.
