The objective of the present investigation was to evaluate the quality of piquín pepper seed through the accelerated aging test in piquín pepper (Capsicum annuum var. Aviculare) collections from the state of Querétaro and Guanajuato. The collections were made in four locations El Patol, El Cuervo and Higuerillas of the municipality of Queretaro and El Tanque of the municipality of Xichu. The vigor of the seed was obtained by the accelerated aging test which consisted of submitting the seeds 24, 48, 72, 96, 120 and 144 h at a temperature of 42 °C and 100% relative humidity, after this period, the seeds are subjected to a normal germination test at 7, 14 and 21 days. The results in the analysis of variance expressed significant effect in genotypes, being the best time for the count performed at 7 days and at 24 h. At 14 days the best times for the witness were zero, 24 h, 48 h and 72 h. On the other hand, the quality of the seed was registered, which presented significant differences for dry stem weight, the highest values were for El Tanque and El Patol. In dry weight of root, weight of one hundred seeds and speed of emergency stand out the collections from El Tanque, El Patol and El Cuervo. Higuerillas presented lower values in the characters indicated above, a difference that could be attributed to environmental conditions.
