 ABSTRACT

The association of characters and their direct and indirect effects on yield are important for crop improvement. Correlation and path analysis were studied in the present investigation for identifying the characters depending upon which the selection would be effective in horsegram improvement. The experimental material comprised 30 diverse genotypes of Horsegram (Macrotyloma uniflorum Lam. Verdc) and studied nine quantitative characters viz. days to 50 per cent flowering, days to maturity, plant height, number of branches per plant, pods per plant, seeds per pod, 100 -seed weight, harvest index and seed yield per plant. The seed yield per plant showed highly significant positive association with number of pods per plant, number of branches per plant and harvest index. The characters number of number of seeds per pod, number of days to 50 per cent flowering, days to maturity were positively associated but non-significant at the genotypic level. Seed yield per plant showed significant and positive association with 100 seed weight at the genotypic level. The character plant height was highly significant and negatively associated with seed yield per plant. The traits number of branches per plant, seeds per pod and harvest index showed high positive direct effect on seed yield per plant.

Keywords: Horsegram, Correlation coefficient, Path analysis, Yield components.
