Abstract: The 500 F₅, F₆ and F₇ RILs Derived from the cross between GPU48 x Uduru mallige were screened for neck and finger blast incidence, in F_5, one RIL were moderately resistant to neck blast, whereas in F_6, four RILs were moderately resistant to neck blast and two RILs were moderately resistant to finger blast whereas in F₇ six RILs were moderately resistant to neck blast and four RILs to finger millet blast. ANOVA showed the effects of checks, varieties and checks vs. varieties were all significant. Significant effects suggested that certain lines exhibited differential resistance and probably possess different resistance gene(s). Significant effects of the location suggests, weather conditions were more conducive for blast. There is lower differences in GCV and PCV, lower difference between GCV and PCV suggests narrow influence of environment on neck and finger blast expression. Kurtosis is positive, indicates the existence of gene interactions.
