Gopimony, Anjitha- A new okra variety through induced mutation
in interspecific hybrids of Abelmoshus Spp.
Many varieties and a large number of mutants have been obtained through induced mutation
approach, but the mutation in most of them is involved in single gene or few loci.

and selection of High yielding strain of Micrococcus glutamicus for glutamic acid production", J.
Unlike genetic modification (or GM), which introduced new material into a plant's genetic make-up, induced mutation
simply accelerates the natural process of spontaneous changes occurring in plants.
Evidence to date suggests that by reducing tillage requirements, soil erosion, water pollution, pesticide use, whilst increasing yields and the capacity to grow crops in previously impossible conditions, GM crops will have a very positive impact on their lives compared with what they might have had had we continued to rely solely on 'conventional' breeding techniques (such as varieties bred by induced mutation
often chosen by 'organic' growers).
There were no significant differences in the levels of induced mutation
among children of exposed women (active smokers, women who had quit smoking when they found out they were pregnant, and women who were only passively exposed to smoke).

However conventionally induced mutation
has some distinct limitations, especially in the applications of crop-breeding, as percentage of desired mutation is very less in the field; by using in vitro techniques with the combination of routine mutagenesis has overawed this obstruction too.
Focusing on induced mutation
in food crops, botanists, agricultural scientists, geneticists, and contributors explore mutagenesis as a tool for food security and sustainable human nutrition, and physiological and molecular aspects of mutagenesis.
Kharkwal and Shu  reported that induced mutation
breeding is becoming more powerful and effective in breeding crop varieties to play a significant role for improving world food security in the coming years and decades.
