Abstract Claviceps purpurea causing ergot maintains to be a problem in commercial cytoplasmic male sterile (CMS)-based hybrid rye growing. The fungal spores compete with pollen during flowering and incidence is reduced highly pollen-shedding stands. This study was carried out identify maternal differences infection the absence of pollen. Ten male-sterile single crosses were tested by needle spr...

Hybrids (2n = 3x = 21) between Aegilops ovata and Secale cereale were produced via embryo rescue. Most hybrid morphological traits were intremediate between parents, the plants grew vigorously but were completely sterile. The average frequency of chromosome associations at metaphase I was 19.57-20.19 univalents and 0.40-0.86 rod bivalents. The fertility of the hybrids was restored by doubling t...

A comparison of mitochondria isolated from 2 and 24 C grown winter wheat (Triticum aestivum L.) and winter rye (Secale cereale L.) seedlings revealed no correlation between changes in swelling and contraction characteristics and extent of cold hardiness. The swelling response changed markedly due to growth at low temperature, but the change was similar for the four cultivars examined. The swell...

In the present study, RAPD-PCR was used to assess genetic diversity of the rye including landrances and new rye cultivars coming from Central Europe and the Union of Soviet Socialist Republics (SUN). Five arbitrary random primers were used to determine RAPD polymorphism in the set of 38 rye genotypes. These primers amplified altogether 43 different DNA fragments with an average number of 8.6 fr...

Four cereals, Hordeum vulgare (barley), Triticum aestivum (wheat), Secale cereale (rye), and Avena safiva (oat), were grown in a defined nutritional medium with and without the arbuscular mycorrhizal fungus Glomus intraradices. Levels of soluble and cell wall-bound secondary metabolites in the roots of mycorrhizal and nonmycorrhizal plants were determined by high-performance liquid chromatograp...

Bu araştırma çavdar (Secale cereale L.)’ın kaba yem amaçlı üretim olanağını ortaya koymak amacıyla yürütülmüştür. Çalışmada çavdarın farklı olum dönemlerinde verim ve besleme değerindeki değişim incelenmiş bu amaçla yerel popülasyonlardan çeşitten “Aslım -95” oluşan 10 genotipi ile kontrol olarak birer tritikale arpa çeşidi kullanılmıştır. Deneme 2018-2019 2019-2020 yetişme sezonlarında Yozgat-...

Intraspecific hybridization in winter rye selection ( Secale cereale L. ssp. ) is a source of intrapopulation genotypic variability with the possibility using effect interpopulation heterosis. The inheritance crop yield, regeneration degree after overwintering and weight 1000 grains reciprocal back F 1 intervarietal hybrids was established. Different types prevailed crossings. had specificity. ...

the short arm of rye (secale cereale l.) chromosome 1 (1rs), besides being part of the rye genome, is present in many hundred wheat cultivars as either 1rs.1bl or 1rs.1dl wheat-rye translocation. in this study, the distribution of the wheat–rye translocation was examined in 33 iranian winter and spring wheat cultivars, nine of which had a known donor of 1rs.1bl translocation and the other 24 we...
