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...

Agronomic performance of six winter wheat dwarfing sources when crossed to isogenic lines for Norin 10 Rht loci

Creator:: Pedretti, Ricardo
Abstract:: Six genetically diverse dwarfing sources of winter wheat were compared to four isogenic lines for the height reducing genes Rht₁ and Rht₂. Parents and generations through the F₃ including backcrosses to the respective parents were analyzed. Seedling response to gibberellic acid and tests for allelism for plant height were employed...

Influence of aluminum toxicity in intergeneric crosses of wheat and rye

Creator:: Lopez-Benitez, Alfonso
Abstract:: A technique previously designed to screen wheat cultivars and segregating populations for tolerance to Aluminum utilizing nutrient solutions in growth chambers was found to be efficient in differentiating among cultivars of wheat, rye, and triticale for tolerance to Al under greenhouse conditions. A 5°C increase in temperature, from 25°C to...

Chemically induced male sterility and natural out-crossing in selected wheat cultivars (Triticum aestivum L. em Thell)

Creator:: Ekse, Ali Osman
Abstract:: Three chemicals SD 55446, SD 55447 and WL 84245 were found to induce male sterility in cultivars of wheat or triticale. Both SD 55446 and SD 55447 when applied at a concentration of 0.896 kg/ha resulted in 90% male sterility. However, SD 55447 caused female sterility at the same concentration...

Nature of inheritance, genotype-environment interaction and association of selected agronomic characters in crosses of winter X spring wheats (triticum aestivum L. em Thell)

Creator:: Brajcich, P.
Abstract:: This investigation was motivated by the apparent increase in genetic variability resulting from the systematic combining of gene pools represented by winter and spring types of wheats. It was the objective of this study to provide information regarding the nature of this genetic variability for nine agronomic characters in populations...

A comparison of two methods of divergent mass selection for heading date in two winter wheat (Triticum aestivum L. em Thell) crosses

Creator:: Frederickson, Leslie John
Abstract:: Responses to two cycles of mass selection for heading date, followed by selfing or intermating, were studied in two diverse winter wheat (Triticum aestivum L. em. Thell) crosses. Selection was bidirectional, resulting in early and late populations for each mating system, cycle, and cross. The influence of mass selection for...

Chemical and genetic evaluation of high lysine and protein in selected barley crosses

Creator:: Helm, James Henry, 1944-
Abstract:: Four agronomically and genetically diverse spring barleys were used in a crossing program to study the inheritance of lysine in barley and to determine its possible association with certain agronomic and morphological characters. The cultivar Hiproly was used as the source of high protein and lysine. Characters measured included plant...

Competitive effect for grain yield of four cultivars in pure and mixed populations in wheat (Triticum aestivum Vill;, Host)

Creator:: Valencia-Villarreal, Jose Antonio
Abstract:: Concerns regarding maintaining wheat yield per hectare and extending the commercial life expectancy of cultivars grown in the Yaqui Valley of Mexico prompted this investigation. Four genetically diverse spring wheat cultivars were grown in pure stands and in all possible combinations at the Northwest Agricultural Research Center at Ciudad Obregon...
