line yesevi-93 (cultivar abidar) was first introduced to dryland agricultural research institute (dari) through the international winter preliminary barley yield trials (iwpbyt) in 1994. it was selected as one the most high yielding lines based on observational and statistical trails (regional barley yield trials) carried out in different locations during 1997-2000. the average yield of abidar ...

lattice design with nine replicates. All accessions were of special interest in the breeding program. Included as a susceptible check was the commercial variety 'Valery.' One row of 'Valery' was planted as a border around the experimental area. Rhizomes were examined 12 and 19 months after planting, and average infestation per plot was rated on the same scale of 0 to 4. Results are in Table 1, ...

ABSTRACT The role of the Co-52 and Co-42 alleles in early activation bean immunity against Colletotrichum lindemuthianum is poorly known. Thus, by using anthracnose-susceptible Sutagao cultivar anthracnose-resistant G2333, this study aimed to evaluate presence SCAR markers, as well their respective defense responses, histochemical tests diferential gene expression. results showed that allele co...

two barley (hordeun vulgare l.) genotypes, radical and cwb, with good to moderate levels of resistance to powdery mildew were crossed with a highly susceptible cultivar (afzal) to determine the genetics of resistance. the parents, fl, f2 and f3 generations of each of the two crosses, were evaluated for powdery mildew resistance in the glasshouse and field at the college of agriculture in karaj ...

wheat is the most important crop of iran and black or stem rust disease is one of the most severe diseases threatning the wheat production. in order to identify new resistant sources against the new race of stem rust virulent on plant with sr 31gene, the selected iranian landraces accessions of national plant gene bank of iran wheat collection were evaluated. the most virulent isolate of puccin...
