Abstract

The present study was aimed to realize the magnitude of variability and character association studies of yield parameters among advanced lines developed through crossing between inbred lines of diverse origin to obtain best performing new varieties to replace existing old varieties in order to enhance area under millet cultivation which provides national nutritional security. The present investigation was carried out to study the variability, heritability, genetic advance as per cent of mean, character association and path coefficient analysis among seventeen advanced lines. The data were recorded on yield parameters like days to 50% flowering, plant height (cm), days to maturity, number of productive tillers per plant, grain yield (kg/ha) and fodder yield (kg/ha). High heritability coupled with high genetic advance as percent of mean was observed for number of productive tillers and grain yield. Correlation study indicated that fodder yield, number of productive tillers and days to maturity had significant positive association with grain yield. The path analysis indicated that fodder yield and days to 50% flowering had positive direct effects on grain yield. Hence, selection may be exercised on these traits to improve grain yield.

Conclusion

The results from the above study revealed that the component characters number of productive tillers per plant, fodder yield and days to maturity can be taken as selection parameters for yield improvement in foxtail millet. These traits have shown high GCV, PCV, high heritability coupled with high genetic advance and has shown positive association with grain yield as per correlation analysis. The path analysis revealed that these traits contribute to grain yield immensely both directly and indirectly through other related traits.
