Mutagenic efficiency and effectiveness of gamma rays and EMS in groundnut (Arachis hypogaea L.)
An experiment was conducted to retrieve some useful chlorophyll mutants in two groundnut varieties of TMV (Gn)13 and TMV 7. The mutagenic efficiency and effectiveness were calculated by using the chlorophyll mutants. In M1 generation, the seedling height was decreased with an increased rate of doses/concentration while lethality and pollen sterility were increased with an increased rate of doses/concentration in both the varieties on both the treatments. In the present study, the chlorophyll mutants were observed in M2
. The four different chlorophyll mutants observed were albino, chlorina, xantha and striata at different crop stages of crop growth. On perusal of data, it was inferred that chlorina occurred at large followed by xantha and albino. Mutagenic effectiveness were significantly higher in gamma rays for TMV(Gn)13 and TMV 7 (4.24 and 2.64) than the EMS which registered as 3.69 and 2.19 respectively. The mutagenic efficiency was increased for injury and decreased for lethality and pollen sterility with an increased rate of doses/ concentration.
