The paper presents smallholder farmers' perceptions on attributes of bread wheat varietiesbased on primary data collected from 524 households in four major wheat growing areas ofEthiopia. The results indicated high value of attainment indices for improved varieties comparedto landraces, which shows how the demanded attributes are embodied more in improved ones.Grain yield and yellow and stem ru...

Seed borne mycoflora associated with ten commercial varieties of wheat viz. Blue silver, Faisalabad 85, Manthar-3, Pak 81, Parwaz 94, Pirsabaq 2005, Punjnad-1, Sariab-92, Sh-2002 and Wafaq-2001 was investigated through standard blotter paper and agar plate method by using Mann-Whitney U test. At least eleven fungal genera were recovered from seeds. The most frequently isolated fungi were Bipola...

Metabolic changes in spikelets of wheat varieties FL62R1, Stettler, Muchmore and Sumai3 following Fusarium graminearum infection were explored using NMR analysis. Extensive 1D and 2D 1H NMR measurements provided information for detailed metabolite assignment and quantification leading to possible metabolic markers discriminating resistance level in wheat subtypes. In addition, metabolic changes...

Sumintary. A spring wheat (Triticumo aestivumin) and(I anl obligate winter wheat (Triticumt compactutm) variety were each grown for 5 weeks in controlled environments at 20 and 250. The threshold for flower induction in the winter wheat was 4 to 5 weeks at 20, whereas the spring wheat had no low temperature requirement for flowering. Changes in the levels of carbohydrate and nitrogen fractions ...

The threshold for flower induction in the winter wheat was 4 to 5 weeks at 2 degrees , whereas the spring wheat had no low temperature requirement for flowering. Changes in the levels of carbohydrate and nitrogen fracti...

in recent years, the russian wheat aphid, has been included worldwidely in the list of the important pests of cereals, particularly wheat plants. in addition to direct serious damage, the aphid is the main vector of barley yellow dwarf, barley mosaic, and sugarcane mosaic viruses. the pest was reported from east azarbaidjan province (iran) a few years ago and it is now widespread in tabriz,...

Wheat landraces carry abundant genetic variation in heading and flowering times. Here, we studied flowering-related traits of two Nepalese varieties, KU-4770 and KU-180 and a Japanese wheat cultivar, Shiroganekomugi (SGK). These three wheat varieties showed similar flowering time in a common garden experiment. In total, five significant quantitative trait loci (QTLs) for three examined traits, ...

This research was conducted to determine the wheat varieties against waterlogging which was clearly increased in recent years. For this purpose, this study was performed at Field Crops and Soil Science Department of Agricultural Faculty of Adnan Menderes University during wheat growth stages of 2007-2008. The experimental design was randomized complete block design with split split plot arrange...

Wheat is grown as a staple crop worldwide. It is important to develop an effective genotyping tool for this cereal grain both to identify germplasm diversity and to protect the rights of breeders. Single-nucleotide polymorphism (SNP) genotyping provides a means for developing a practical, rapid, inexpensive and high-throughput assay. Here, we investigated SNPs as robust markers of genetic varia...

Fusarium culmorum is one of the most important causal agents of Fusarium head blight (FHB), results in yield and quality reductions and mycotoxin accumulation. It predominates on cereals in North-West of Turkey in cereal growing fields. In this research the aggressiveness among the F. culmorum isolates and reduction on yield was evaluated. Two wheat varieties (Golia and Ceyhan) and 16 isolates ...
