INDUCTION OF MACROMUTATIONS IN CLUSTER BEAN (Cymopsis tetragonoloba (L.) Taub.) THROUGH MUTAGENS

Dr. Manisha Shamrao Shinde, Dr. Anil Deoba More

Abstract :

Cluster bean (Cyamopsis tetragonoloba (L.) Taub.) is drought tolerant protein rich legume crop belongs to family Fabaceae. The cultivar of cluster bean ‘P.N.B’ was treated with chemical mutagen Ethyl Methane Sulphonate (EMS) at the concentration of 4mM, 7mM, 9mM, 10mM, and physical mutagen gamma rays at the dosage of 100Gy, 200Gy, 300Gy, 400Gy and also with combination of both (Gamma rays and EMS) like 100Gy + 10mM, 200Gy + 9mM, 300Gy + 7mM, 400Gy + 4mM.

Macromutations play an important role to assess the effect of mutagenic treatments. In present investigation all the mutagenic treatments are successful in inducing macromutaions in Cluster bean, but the combination shows the highest range of such mutations. In the combination of 300Gy + 7Mm the number of pods increased significantly as compare to the control. The other parameters like length of pods, seeds per pod and 100 seeds weight also show the significant results.
