the new cereal, primary tritipyrum is a synthetic amphiploid derived from crossing between durum wheat varieties (triticum durum, 2n=4x=28, aabb) and wild coach grass species (thinopyrum bessarabicum, 2n=2x=14, ebeb). in this study the genotype × environment interaction effect containing change in rank and value for grain yield of seventeen genotypes including eight primary and combined primary...

Comparison of Salinity Tolerance in Non-Iranian Primary Tritipyrum Promising Lines with Two Wheat Cultivars Germination Stage

Background: Non-Iranian Primary Tritipyrum (2n=6x=42, AABBEbEb) set seed after Triticale (2n=6x=42, AABBRR) and Tritordeum (2n=6x=42, AABBHcHc) but, due to a few undesirable agronomic traits, it cannot fulfil the commercial expectations of farming. Objectives: To remove these deficiencies, six hexaploid Tritipyrum lines were crossed with four Iranian bread wheat cultivars which led to the...

synthetic plants as well as wild crop species are valuable genetic resourses. to determine the genetic variation in triticale, tritipyrum as well as wheat lines, genomic dna of this amphiploid including thinopyrum bessarabicum and durum wheat were amplified using 32 random and 22 semi random primers. primers that could produce clear, polymorphic and repetitive bands are used for determination o...

to remove unfavorable traits of new cereal tritipyrum (2n=6x=42, aabbebeb), various crosses between primary tritipyrum lines (female) with iranian bread wheat varieties (2n=6x=42, aabbdd) was performed and a f2 selfing population consisted of 1810 possible secondary tritipyrum seeds (2n=6x=42, aabbd(0-14) eb(0-14)) were produced. the chromosome constitution and homology index of 11 plants of th...

the new cereal, primary tritipyrum lines, is an artificial hexaploeid wheat (2n=6x=42, aabbebeb) from crossing between triticum durum (2n=4x=28, aabb) and thinopyrum bessarabicum (2n=2x=14, ebeb) species. in this study the salt tolerant potencial of new primary tritipyrum lines for nacl (0, 100, 200 mm) in an hydroponic experiment was studied in a completely randomized split plot design with th...

soil affected by salt (nacl) is a major problem worldwide and in areas with potential agriculture; lands in many countries are not enough to support crop production. the development of salt tolerant cultivars would be enhanced by better understanding of the genetic control of tolerance to salt stress. a new cereal, tritipyrum, a range of amphiploids between triticum spp. and thinopyrum spp....
