Abstract

Black gram is one of the important crops in the family Leguminosae. It has been used widely for its protein contents and other nutrients. To design and improve the breeding program the characteristics of the crop are foremost important. For which the analysis of correlation and path coefficient pays way to select the desirable characters for the improvement of black gram. In this study, twelve genotypes were evaluated for ten biometric traits viz., days to fifty percent flowering, plant height, number of branches per plant, number of clusters per plant, number of pods per plant, number of seeds per pod, pod length, 100-seed weight, seed yield per plant, days to maturity which revealed that number of clusters per plant and number of pods per plant had a significantly positive correlation with yield. From the path analysis, number of branches, days to fifty percent flowering, number of seeds per pod, and plant height were recorded with a very high direct effect on single plant yield. Thus, the traits viz., hundred seed weight, number of branches per plant, and number of pods per plant could be selected for improving seed yield in black gram.

Conclusion

In conclusion, the correlation analysis indicated Single plant yield was positive and significantly associated with hundred seed weight, number of branches per plant, and number of pods per plant. Results obtained from path analysis revealed that number of branches, days to fifty percent flowering, number of seeds per pod, and plant height were registered with very high direct effect on single plant yield. Hence characters viz., hundred seed weight, number of branches per plant, and number of pods per plant could be utilized as selection criteria for improving seed yield in black gram.
