Abstract

Finger millet is famine reserve crop and lacks high yielding varieties. The current investigation for correlation and path analysis in finger millet was done using 101 genotypes and sixteen parameters. Grain yield per plant was found to be highly significant and positively correlated with days to 50 % flowering, plant height, main ear head length, finger width, finger length, 1000 seed weight, fodder yield per plant, harvest index, calcium content and iron content. Direct positive selection for such characters would be effective for improving grain yield per plant. Path coefficient analysis revealed that for improving yield in finger millet, weightage in selection should be given to harvest index, fodder yield per plant, fingers per earhead, finger length, iron content and calcium content. Selecting for above traits in segregating generations can result in high yielding varieties.

Conclusion

All in all, according to correlation studies, selection practiced for days to 50 % flowering, plant height (cm), main ear head length (cm), finger width (cm), finger length (cm), 1000 seed weight (g), fodder yield per plant (g), harvest index (%), calcium content (mg/100g) and iron content (mg/100g), as they are highly correlated at both genotypic and phenotypic levels, would automatically result in the improvement of grain yield even though direct selection for improvement had not been made for the yield character. In the present study, overall picture of path coefficient analysis revealed that for improving yield in finger millet, weightage in selection should be given to harvest index (%), fodder yield per plant (g), fingers per earhead, finger length (cm), iron content (mg/100g) and calcium content (mg/100g). Selecting such traits would directly or indirectly contribute in the improvement or increase in grain yielding ability as these traits were highly correlated and had high direct effect on yield which would allow simultaneous improvement.
