Farmer’s seed sources and seed quality: 2. seed health
The study assessed the health quality of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) seed samples collected from formal and informal sector in Ethiopia and Syria. In Ethiopia, several seed-borne fungi were found on wheat samples: Cochliobolus sativum, Fusarium avenaceum, F. graminearum, F. nivale, F. poae and Septoria nodorum. C. sativum was predominant with 84% of samples...
متن کاملFurther Experiments on the Control of Barley Smuts
In 1930 the writer (7Y presented the results of early experiments on the control of barley covered smut (Ustilago hordei (Pers.) Kell, and Sw.) with dust fungicides, together with a rather comprehensive review of the pertinent literature on the subject up to that time. The development since then of new fungicidal dusts, some of which were effective in controlling barley stripe (Helminthosporium...
متن کاملKP4 to control Ustilago tritici in wheat: Enhanced greenhouse resistance to loose smut and changes in transcript abundance of pathogen related genes in infected KP4 plants
Ustilago tritici causes loose smut, which is a seed-borne fungal disease of wheat, and responsible for yield losses up to 40%. Loose smut is a threat to seed production in developing countries where small scale farmers use their own harvest as seed material. The killer protein 4 (KP4) is a virally encoded toxin from Ustilago maydis and inhibits growth of susceptible races of fungi from the Usti...
متن کاملHigh-density genetic mapping of a major QTL for resistance to multiple races of loose smut in a tetraploid wheat cross
Loose smut, caused by Ustilago tritici (Pers.) Rostr., is a systemic disease of tetraploid durum wheat (Triticum turgidum L.). Loose smut can be economically controlled by growing resistant varieties, making it important to find and deploy new sources of resistance. Blackbird, a variety of T. turgidum L. subsp. carthlicum (Nevski) A. Love & D. Love, carries a high level of resistance to loose s...
متن کاملGenetics and resistance / Génétique et résistance Identification of resistance genes to barley covered smut and mapping of the Ruh1 gene using Ustilago hordei strains with defined avirulence genes
Covered smut of barley (Hordeum vulgare), caused by Ustilago hordei, is a seed-borne disease. To identify and map disease resistance genes, current Canadian barley cultivars, parents of six barley mapping populations, and four differentials namely ‘Hannchen’ (Ruh1), ‘Excelsior’ (Ruh2), ‘Plush’ (Ruh6), and ‘Odessa’ (universal susceptible), were evaluated. Six mated combinations of U. hordei spor...
