Impact of ethyl methane sulphonate on M1 attributes of Groundnut with special emphasis of amino acid profiling

Abstract

The present investigation was undertaken  to know the effect of EMS on  groundnut cultivar TMV-7 particularly for M₁ generation with special reference to amino acids. The healthy and viable seeds of groundnut cultivar TMV-7 were exposed to different concentrations of EMS. The chemical mutagens were screened against groundnut  ranged from 10 to 50mM and sown in the field along with control. The various growth, morphological parameters like percentage of seed germination, survival percentage plant height, number of branches, days taken for flower initiation , total height at time of harvest, root length,  number of lateral roots, number of pods per plant and 100 seeds  weight were decreased with increasing concentrations of EMS. The amino acid analysis also carried out in control, EMS derived M₁ plants grown in field. The amino acid contents were  recorded in  both positive and negative tendency.
