Examination of seed quality parameters of three pepper varieties in a five-year period (Capsicum annuum L.)

Abstract

Sweet pepper (Capsicum annum L.) is considered one of the most popular vegetables in the world. During five consecutive years (2017-2021) the most important indicators of seed quality (seed germination, energy, seed purity and moisture) and health safety were analyzed in three varieties of peppers (Capsicum annuum L.): Palanačko čudo, Župska rana and Duga bela. During the research, very high values of all important parameters of seed quality were determined. The average determined seed purity was 98.6 % with a variation over the years of examination from 99.10% to 99.9%. Seed germination varied in the range of 73% to 94%, while the average germination was 86%. Germination energy was in the range of 61% to 88%. Seed moisture data showed that it was in the tolerance range of 6.3% to 7.4% per test year, with an average value of 6.9%. Alternaria spp and Fusarium spp were detected in minimal percent or no detection on variety of Palanačko čudo. Duga bela had the highest percentage of Alternaria spp. in 2020 and 2021, which were 2% and 3%, respectively. Fusarium spp. was presented in percentage more than in Župska rana and Palanačko čudo. The total germination of the Palanačko čudo, Župska rana and Duga bela during the observed five-year period was above the legal level of minimum and can be classified as quality seed.
