Abstract

The present investigation was carried out for fifty finger millet genotypes that were tested for four different environments viz., E1 and E2 at Student Research Farm, C.S.A.U.A. &T. Kanpur and E3 and E4 sown at Research Farm, Daleep Nagar, Kanpur. The genotypes were evaluated in randomized block design with three replications to derive Correlation coefficient and Direct and Indirect effects in fifty different genotypes of finger millet to estimate analysis of variance, mean, correlation and path analysis. Analysis of Variance showed significant differences for all characters under study at 1% and 5% Level of Significance, indicated that presence of ample genetic variation among genotypes. Association studies revealed that grain yield per plant exhibited highly significant positive correlation at genotypic level with number of fingers per ear, ear head weight, straw yield per plant, harvest index and 1000 grain weight for all the environments and pooled and harvest index for E1 showed maximum positive direct effect (0.919) followed by E2 (0.899), straw yield per plant for E2 (0.830). Path studies reported that grain yield per plant showed positive direct effect with all the characters except days to maturity and earhead width at both genotypic and phenotypic level. Thus, these traits are identified as the efficient and potential for indirect selection for the improvement of productivity in the present experimental material. The challenge of the study is to find out the character associations to the yield and to estimate the direct and indirect effects of each character on yield. Ultimate aim is to enhance the yield and also enhance the quality of grain.

Conclusion

The correlation coefficient and path coefficient study revealed that grain yield per plant exhibited significant positive correlation with number of productive tillers per plant, number of fingers per ear, finger length, ear head width, ear head weight, straw yield per plant, harvest index and 1000 grain weight. It can be concluded that biological yield/plant, 1000 seed weight and oil content are the major yield contributing traits and must be considered during selection.
