In order to evaluate the quality of fields and seed plots in wheat seed production of provinces including, Khozestan, Boshehr, Hormozgan and South kerman (Jiroft) an experiment was conducted in 2019-2020. The distribution noxious weed, other crops and other species in fields was recorded at filed inspection forms. Then, in order to surveing of seed production situation in companies, including attainment percent of green surface, final capproval surface, amount of seed production and processing determined. Also, seed plots were analyzed in seed quality analysis laboratory for physical purity, seed germination percent, number of noxious weed seed and number of other crop seed.
The results indicated that the most weeds that have been observed in fields of wheat seed production were Convolvulus arvensis, Avenea fatua, Malva sylvestris, Hordeum spontaneum and Acroptilon repens. Evaluation of fields and laboratory analysis showed that the seed quality was different among companies. In Kozestan, in terms of farm factors, three companies (Shahid Beheshti and Arya Kesht and Bazravaran Karkheh) were the best. In terms of seed quality characteristics, Inaddition, Safi Abad Research Center and Shavor Research Station, two companies, Sorkheh Daneh and Falahat Daneh were superior. In Bohshehr, in terms of farm factors, two companies, Sadaf Daneh and Khosheh Talaei Dashtestan under irrigated cultivation conditions, and two companies, Khosheh Talaei and Bahar Gostar-e- Shabankareh, under dryland cultivation conditions, were superior. In Seed Decomposition Labotratory, produced seeds from Bahar Gostar-e- Shabankareh, had better quality. In Hormozgan, in terms of farm management and seed quality characteristics, Gandomkaran Sahel company were superior with compared to Haji Abad Cooperative. In South kerman region (Jiroft), in terms of farm management, Rodbar Zamin company and in terms of seed quality characteristics, Hammon Company, were superior. It can be conchuded that seed production in fildes under contract with top companies, in terms of farm management and seed quality characteristics, reduced the risc seed peoduction and the produced seeds will be of higher quality.
