Abstract

The aim of this study was to figure out genetic variability, correlation and path co-coefficients for seven traits in 42 F3 families of the cross Azucena/CB 87R*1 aimed for developing new restorer lines with indica tropical japonica background for their utilization in a hybrid program. The population exhibited high PCV  and GCV  for the traits viz., the number of productive tillers per plant, panicle weight and single plant yield. For the same traits, high heritability combined with high GAM was also deduced.  The traits panicle weight, the number of productive tillers per plant, panicle length, flag leaf length and flag leaf width showed positive and significant associations with single plant yield. Though the traits panicle weight and the number of productive tillers were negatively correlated, they both exerted a high direct effect on single plant yield.
