Mutant lines induced by ethyl methane sulfonate (EMS) have been used for crop improvement and functional genomics. Since pepper is very recalcitrant to be transformed, EMS mutagenesis could be an alternative method to generate useful mutant lines and to characterize the function of genes. We have developed mutant lines consisting of about 3,938 M2 mutant lines using Korea local landrace, C. annuum ‘Yuwolcho’. Yuwolcho has suitable traits for mutagenesis such as early flowering and maturation, large number of seeds per fruit, and susceptibility to various diseases. Up to now, 917 M2 mutant lines were evaluated to confirm the effect of EMS. M2 mutant lines have shown variations in plant stature (small size, dwarfism, and early death), leaf development (light color, variegation and morphological change) and flower (inflorescence, morphological change) and fruit (size and color). We observed the largest morphological variation in leaf development. Most of these mutant phenotypes were inherited recessively. In addition, we are applying cel1-based TILLING to identify useful mutant lines. We will apply cel1-based TILLING to identify useful mutant lines. We are expecting that these mutant lines will be very useful to study the function of genes in C. annuum.
