Performance of cultivars, hybrids and composites of winter wheat (Triticum aestivum L. em Thell) grown at three locations

Creator:: Verges, Ruben P.
Abstract:: The objective of this study was to compare three genetically different groups of winter wheat for their grain yield. Experimental material consisted of parental lines grown in pure stands, hybrids, and 1:1 mixtures of the parental combinations. Three sites were employed to evaluate possible interactions between the different groups across...

Possible association between dwarfing genes Rht₁ and Rht₂ and the reaction to Septoria tritici blotch in winter wheat (Triticum aestivum L. em Thell)

Creator:: Baltazar, Baltazar
Abstract:: Four isogenic lines possessing different combinations of height reducing genes Rht₁ and Rht₂ from 'Norin 10' were crossed to a short stature, early maturing, septoria susceptible cultivar identified as the 'Tibet Dwarf'. The isogenic lines originated from the backcross population of 'Itana'/3/'Norin 10'/'Brevor 14'//6*'Itana'. Parents, F₁ and F₂ generations provided...

Combining ability and associations of agronomic traits involving three sources of dwarfism in wheat (Triticum aestivum, L. em Thell)

Creator:: Maya de Leon, Jose Luis
Abstract:: Three genetically different dwarf cultivars of spring wheat were evaluated as potential sources of short stature to use in a wheat improvement program. The study involved a five parent diallel cross which included a semidwarf, a standard height and three dwarf cultivars. The genetic sources of dwarfism included a Norma...

Assessment of genetic resistance to strawbreaker foot-rot (Pseudocercosporella Herpotrichoides) in selected winter wheat (Triticum aestivum L.) cultivars

Creator:: Encinas-Mungarro, Andres
Abstract:: Strawbreaker foot-rot is a major limiting factor to cost efficient winter wheat production in the Pacific Northwest. Development of resistant cultivars has been hindered by the lack of adequate levels of genetic resistance and screening techniques which can consistently detect desired genotypes. Studies were conducted to determine if the reported...

Possible compensations of the components of grain yeild in wheat (Triticum aestivum L.) as influenced by genotype by environment interactions

Creator:: Bedoshvili, David
Abstract:: Despite many investigations genotype by environment interaction remains one of the least understood factors in plant improvement. Understanding genotypic differences responsible for such interactions could assist in making more informed breeding decisions. The components of yield being less complex than grain yield per se may be useful for selection to...

Identification and inheritance of factors influencing the rate and duration of grain fill in selected wheat populations, (Triticum aestivum L. em Thell)

Creator:: Chuhe, Chen
Abstract:: To study the grain filling traits in wheat, two winter cultivars and four spring cultivars were selected. The resulting Fl, F2, F3 and backcrosses were tested. The following measurements were made: a) Visual traits for physiological maturity (PM), b) Grain dry weight accumulation, c) Regression models for grain filling period,...

Aluminum toxicity studies in rice (Oryza sativa L.)

Creator:: Martinez-Racines, Cesar P.
Abstract:: A nutrient solution technique developed for wheat was used to determine tolerance of rice cultivars to aluminum (Al) toxicity. Pre-germinated rice seed was placed on top of a screen and allowed to grow on the Al-free solution for 72-96 hours or until the primary root was 2-3 cms long. Seedlings...
