Wheat seed production in
Although, all tested samples belong to one variety ”yocora rojo”, results showed marked variation in seed quality between the two seasons and a significant variation among seed sources in all studied traits. Significant variation was observed in seed purity, in which several samples failed to reach 98% purity level required for seed certification. In addition, poor germination percentages were observed for most tested samples, in which 7 out of 11 authorized samples failed to pass the 92% germination required for certification in both seasons. Furthermore, seed gravity varied among samples. Significant variation was, also, observed for percentage of seeds with black point. All seed sources had seeds with black point in the first season ranging from 6 to 48%. However, low incidents of seeds with black point were observed in the second season. Seeds with insect damage were observed in 6 seed sources in the first season and in two seed sources in the second season.
This study has shown that wide variation in seed quality among locally produced wheat seeds exist as result of weak technical supervision on production and treatment of seeds. Therefore, there is an argent need to develop an effective field inspection and to apply seed production requirements to clear the market from poor quality seeds.
