Abstract: An investigation in finger millet was carried out during summer and kharif 2016 to study variability parameters in F₄ and F₅ progenies of three crosses with contrasting maturity duration with common female parent (PS-1) and different male parents (VL-315, OEB-526 and MR-6). The F₅ progenies were also screened for reaction to neck and finger blast under natural infection conditions at two locations. The PCV and GCV values were moderate to high for number of tillers, ear weight, grain yield and straw yield. Significant positive association of grain yield was evident with earhead weight, total tillers, productive tillers and fingers ear^-1Maximum progenies recorded a resistant score (<5) for neck blast infection. For finger blast, most progenies belonging to PS-1 × VL-315 and PS-1 × OEB-526 were resistant or moderately resistant. However, most progenies from the cross PS-1 × MR-6 were moderately susceptible to finger blast. The progenies with high grain yield and appreciable resistance to blast infection were identified in each of the crosses. Among these, the progenies PSVL-16 (PS-1 × VL-315), PSOB-12 (PS- 1 × OEB-526) and PSMR-30 (PS-1 × MR-6) showed comparatively better performance.
