Abstract

Genetic variability for rust, blast, yield and yield components was carried out for 150 inbred lines (Dharwad andVijayapur) along with two susceptible checks ICMB-94555 and ICMB-92777. Significant differences (p<0.05) wererevealed by the analysis of variance statistically, which showed the genetic variability’s existence for various characteristicsin inbred lines. Maximum heritability was documented for grain yield (kg/ha) followed by panicle length and plant height.Maximum genetic advances in means were observed by grain yield, fodder yield, height of plant (cm) and panicle length(cm). High broad sense heritability was noticed for all the traits indicating that simple selection process is indicative ofgenetic improvement in desired direction.
