Seeds of three diverse genotypes of grasspea viz. Nirmal, Biol-212 and Berhampur Local treated with EMS (0.5% and 1%), gamma rays (400, 500 and 600 Gy) and in combination (400Gy+0.5% EMS and 400 Gy+1% EMS) were constituted as initial material for the present study. The experiment was conducted for 2012-15 winter seasons at District Seed Farm, BCKV, West Bengal, India. Correlation study was computed between yield and nine different yield components at different chemical concentration and radiation level in M2 and M3 generations. The correlation coefficient between seed yield per plant and its components were estimated at phenotypic level. The result revealed that all the characters showed significant and positive correlation with seed yield at different mutagenic treatment but not in all treatments however, 100 seed weight was positively correlated with seed yield at all mutagenic treatment in both generations (except 500 Gy treatment of Nirmal in M2 generation) professing that 100-seed weight was vital yield improving character in all three varieties of lathyrus under study. Henceforth, it can be suggested that selection of plant for different yield improving characters will be more effective in combination treatments in case of grasspea varieties under studied as maximum significant and positive relationship between yield and its components were noted in combination treatments.

Keywords: Correlation, EMS, Gamma rays, Grasspea, Yield components.
