Abstract:
Greengram (Vigna radiata (L.) Wilczek) 2n= 2x = 22 is cultivated on a large scale in several parts of the world which is the third most valuable pulse crop. Pulses are the primary resource of protein to meet up the nutritional requirement of the world. The most important objective in any crop improvement programme is to increase the seed yield through development of high yielding varieties with resistance to pest and diseases. Thus during the course of Rabi 2021-2022, an experiment was put through to determine correlation and path analysis between yield and its components of Greengram. A total of 189 F₃ progenies derived from the cross VBN2 x V2802BG along with parents and checks were utilized for the study and observed for nine quantitative characters viz., days to 50% flowering, plant height (cm), number of branches per plant, number of clusters per plant, number of pods per plant, pod length (cm), number of seeds per pod, 100 seed weight (g) and seed yield per plant (g). The results illustrated that pods per plant (0.969), clusters per plant (0.828), plant height (0.570) witnessed positive correlation coefficient with seed yield per plant which is highly significant. Pods per plant followed by plant height expressed highest positive direct effect on seed yield which is disclosed by path coefficient analysis. Thus while designing a breeding strategy foremost significance has to be given to these attributes to enhance the seed yield in greengram.
