Abstract

An experiments evaluating vigor of storability of seeds of several genotypes of sorghum were conducted during March - October 2015. The sorghum seeds harvested from the planting area in Village of Marhaen, Sub district of Sulusuban, District of Central Lampung, Lampung Province, Indonesia were used in this experiment. The accelerated ageing method with temperature of 40OC and relative humidity of 100% for 0 (control), 2, 4, …, 16 days were used to make seed ageing took place fast. After each treatment applied, viability of sorghum seeds were evaluated to measure percentage of normal seedling (PNS), germination speed (GS), seed leakage (SL), and percentage of dead seeds (PDS). Grouping genotype based on vigor of storability was conducted using cluster analysis with similarity of 70% by variable of PNS. Result showed that the 34 genotypes can be grouped into four groups of vigor of storability, namely high vigor (9 genotypes), medium-high vigor (7 genotypes), medium-low vigor (9 genotypes), and low vigor (9 genotypes). Keywords: accelerated ageing, sorghum seed, vigor of storability.
