Abstract

To evaluate the quality of fields and seed plots in two wheat seed production companies in Tehran (1) and Alborz (2) provinces. The experiment was conducted in 2018-2019 on Sirwan, Baharan, Sivand, Pishtaz, Rakhshan, Pishgam, and Persian gold cultivars at Seed and plant Certification and Registration Research Institute according to PROJECT NO: 2-08-08-021-971216. The distribution of noxious weeds, other crops, and other species in fields was recorded. Also, seed samples were analyzed in a seed quality analysis laboratory for seed germination percent and physical purity. The results showed that the fields of company 2 were better than company 1. As a result, the number of other crops in fields of companies 2 and 1 were observed at 1.1 and 2.2, respectively. Also, the number of other species in fields was recorded for companies 2 and 1, 9.1 and 9.9, respectively. The most weeds that have been observed in fields and seed samples were Avena fatua L. In addition, 66.1% and 39.2% of total Avena fatua L. were related to companies 1 and 2, respectively. Meanwhile, according to the estimated seed sample for the number of noxious weeds and other crops before processing, seed production of company 2 was better than company 1. Also, wheat seed yields for the two companies were recorded at 5.0 and 4.6 tons per hectare, respectively. The physical purity was 99.6% in the two companies, but the normal seedling of companies 2 and 1 was 93.9% and  93.6%, respectively.
