Studies on chlorophyll spectrum and mutation effectiveness in M2 generation of Sesame (Sesamum indicum L.)

Abstract

Ten desirable macro mutants in TKG-55 sesame (Sesamum indicum L.), resulting from induced NaN3 and combination treatment with EMS chemical mutagenesis, have been identified for: viridis (seedling color as marker, increased seed protein content), Albino (White), Xantha (Yellow), Chlorina (Light green), Albomaculata (White dots on green leaves), Alboviridis (Initially white and later becomes normal plants), Xanthaviridis (Initially yellow and later become normal plants). All mutant traits were recessive compared to normal, with viridis showing digenic inheritance and the others monogenic. Along with macro mutants were initially observed for germination, survival and lethality percentage respectively.
