Pathogenic fungi found in wheat seeds and medium early maturity, produced in three parts of Rio Grande do Sul, Brazil

Descripción del Articulo

Seed samples of wheat harvest in 2010 from Santo Augusto, Passo Fundo and Vacaria, RS; were plated on gerbox acrylic sterilized culture medium PSA (potato, sucrose and agar) plus antibiotics. Were used 400 seeds of each cultivar total of 45 cultivars. Were distributed equally spaced 25 seeds in each...
