Dalvi (1990) and Rudraswami *et al*., (2006) also noted similar results in horsegram with

The data recorded in (Table-3) indicated that all the treatments of GR and combinations had succeeded in reducing the number of days required for first pod maturity as compared to control. The combination treatments were highly significant. The average minimum number of days (57.70 DAS) required for first pod maturity was noted in 400Gy + 0.4%EMS. The data obtained for M3 generation for this trait was on par with of M2 generation (Table-4). All the treatments of GR + EMS, caused reduction in number of days required for first pod

The data recorded in (Table-3) revealed that the some of GR and GR + EMS treatments had stimulatory as well as inhibitory effect. In M2 generation maximum number of pods per plant (83.80) were noted in 300Gy than control (71.20). The minimum number of pods per

Results recorded on 1000-seed weight (Table-3) indicated that all the treatments of GR were non significant but the combination treatments such as 300Gy + 0.4%EMS and 300Gy + 0.5%EMS (30.50g and 29.80g) had shown considerable increase in 1000 seed weight over control. The results of M3 generation were on par with M2 generation (Table-4).
