Abstract:
A study entitled “Studies on correlation and path analysis in Horsegram (Macrotyloma uniflorum)” was performed at the Instructional cum Research Farm of IGKV CARS RMD, Ajirma, Ambikapur, Surguja (C.G.), during Kharif 2021 in randomized block design (RBD) with three replications with twenty-two genotypes of horsegram. A study of correlation and path coefficient analysis for yield and yield attributes were carried out with twelve characters. The correlation analysis indicated that seed yield quintal per hectare exhibited highest significant positive association with number of seeds per pod followed by harvest index (%), 100 seed weight (g), number of clusters per plant, days to 50% flowering, days to maturity and number of pods per plant at genotypic level. Path analysis revealed that highest positive direct effect was exhibited by days to 50% flowering followed by days to maturity, plant height (cm), number of branches per plant, number of clusters per plant, number of seeds per pod, number of pods per cluster, biological yield quintal per hectare and harvest index (%). Harvest index is direct effect and equal to correlation. This suggested that selection for these characters will help in isolating highly yielding genotypes. Thus, these traits may be used as selection criteria for screening of promising horsegram genotypes.
