Received: 02-03-2019, |
Seeds of M1 generation of Hyacinth bean (Lablab purpureus L.) sweet was raised by treated the varieties Konkan Bhushan and Konkan Wal-2 with varied concentration of chemical mutagens (EMS- 0.05%, 0.10%, 0.15% and SA- 0.010%, 0.015%, 0.020%%) and physical (Gama rays- 5KR, 10 KR, 15 KR) mutagen. The seed germination percentage, seedling height in cm and survival of plant percentage in M1 generation was noticed. Highest germination percentage was 83.07 at 0.05% EMS and least germination percentage noticed at 0.020% SA treatment 68.88 in Konkan Bhushan and 85.77 at 0.05% EMS and least germination percentage at 0.020% SA treatment 70.58 in Konkan Wal-2. Highest seedling height was 9.11 was noticed at 0.05% EMS and lowest seedling height was noticed at 0.020% SA treatment 6.60 in Konkan Bhushan and 9.77 at 0.05% EMS and lowest seedling height was noticed in 0.020% SA treatment 6.77 in Konkan Wal-2. An increase in concentration of EMS, SA and Gamma rays reduced the percentage of survival of plants at maturity. |
