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.

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 [5] 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.
