Abstract

Seed vigour evaluation is important as one of seed quality parameters to meet the farmers demand. The direct and indirect methods could be used to test the seed vigour. Even though, the different population cultivar may show a different response when vigour test. Therefore, the accurate method is needed. In this study, we used UNPAD Mutant (one population) and Non-Mutant (two populations) sweetcorn lines to determine the characteristics of vigour among populations after 2 months storage using direct (vigour index and normal dry seedling) and indirect (electrical conductivity) methods. The results showed that there were significant difference among populations (Tukeys test) on electrical conductivity parameter at 0 month and normal seedling dry weight parameter at 2 months after storage. Besides, we found the significant correlation between vigour index and electrical conductivity at 0 month and between normal seedling dry weight and vigour index at 2 months after storage. We assumed that the significant correlation between two parameters in this study due to the significant difference among populations at the time of measurement. These results suggested that among populations have different vigour characteristic. The electrical conductivity and normal dry weight seedling were an important approach to investigate seed vigour.
