Assessment of resistance and inheritance to Barley Yellow Dwarf Virus disease (BYDV) in five wheat cultivars (Triticum aestivum L.)

Creator:: Tola, Jaime
Abstract:: Barley Yellow Dwarf Virus (BYDV) is a major disease of wheat. Unfortunately, unlike barley where the Yd2 gene provides adequate levels of resistance, the situation in wheat is more complex. This study was designed to provide information regarding: 1) evaluation of methods of measuring resistance among selected cultivars; 2) identification...

Possible association of grain protein content, harvest index and biological yield in winter wheat populations

Creator:: Costa, Jose Maria
Abstract:: A negative relation between grain protein content and grain yield is frequently observed in wheat (Triticum aestivum L. em Thell) i.e. as grain yield increases, grain protein decreases. It has been suggested that the inverse relation between grain yield and protein is in part the result of developing high yielding...

Factors associated with stand establishment and subsequent grain yield of seven wheat cultivars and selected progeny (Triticum aestivum, L em thell) when grown under three diverse environments

Creator:: Vahabian, Mohammad Ali

Full Text:: is a controversial subject among the plant breeders. Taylor and McCall (1936) presented data

Feasibility of developing bread wheat cultivars with acceptable protein content for non-traditional areas

Creator:: Lorenzo, Ariel
Abstract:: The objective of this investigation was to evaluate the possibility of developing high yielding wheat cultivars whose flour would result in acceptable loaf volumes for non-traditional bread wheat growing areas. Spring wheat germplasm employed included high protein hexaploid derivatives from Triticum dicoccoides, and selections from Argentina with good bread milling...

Nature of inheritance and association of time, duration and rate of grain filling and subsequent grain yield in crosses of winter and spring wheats (Triticum aestivum L. em Thell)

Creator:: Choi, Byung Han
Abstract:: The nature of inheritance and possible associations for traits influencing earliness and grain yield were investigated using a four parent diallel of winter and spring wheat cultivars. More genetic variability was observed for the traits measured in segregating populations resulting from crosses between winter and spring type wheats in contrast...

Duration and rate of grain filling and subsequent grain protein content in selected winter wheat populations

Creator:: Mou, Beiquan
Abstract:: The lack of information regarding the inheritance of the duration and rate of grain filling, and the possible relationship between grain fill and grain protein content in wheat prompted this study. Early maturing Chinese cultivars, 'AI Feng 2' and 'CB 83-52', and late maturing cultivars adapted to Oregon, 'Stephens' and...

Modifying selected factors to classify levels of resistance or tolerance in wheat to Septoria Tritici Blotch

Creator:: Re, Jose Vicente
Abstract:: Influence of abiotic and biotic factors were examined in selected winter wheats previously identified as representing a range of responses to septoria infection. In the greenhouse two and three inoculations identified resistance when disease severity was assessed either for the top four leaves or the flag leaf respectively. Kernel number...

Adaptability of winter wheat cultivars to dryland conditions and their response to water stress

Creator:: Keim, Don Lee
Abstract:: Winter wheat cultivars (Triticum aestivum) were evaluated for their response to water stress and adaptability to a wide range of moisture limited environments. Grain yield was analyzed for ten cultivars at six locations across four years. Regression of the cultivar mean on the year-location mean was used as a measure...

Gluten protein polymeric composition and allelic variation as related to bread-making quality in durum wheat (Triticum turgidum L. var. durum)

Creator:: Ammar, Karim
Abstract:: Attempts to develop dual-purpose durum wheat cultivars for both pasta and bread-making have been unsuccessful. To better understand this limitation, thirty durum genotypes, selected based on their diverse geographical origin, and five bread wheat cultivars were compared as to their flour mixing properties, dough physical characteristics and baking performance. The...
