Inheritance and association of earliness and grain yield in four winter x spring wheat crosses (Triticum aestivum L. em Thell.)

Creator:: Firat, Ahmet Ertug
Abstract:: Parental and segregating populations derived from four winter x spring wheat crosses were investigated to obtain information concerning the inheritance and association of earliness, grain yield and yieldrelated traits. Feasibility of selecting in early generations for these characteristics was also evaluated. Four winter wheat cultivars (Hyslop, Yamhill, Bezostaia 1, and...

Heritability estimates and associations for protein content and grain yield involving four winter wheat crosses (Triticum aestivum Vill., Host)

Creator:: Solen, Polat
Abstract:: Four agronomically and genetically diverse winter wheat parents were utilized as the experimental organisms. Atlas 66 and NB 68513 were selected as cultivars with a high and stable protein content when grown under different environmental condidtions. They are intermediate for grain yield when grown in the Pacific Northwest. Yamhill and...

Evaluation of early generation testing in a diallel cross involving four winter wheat cultivars (Triticum aestivum Vill., host)

Creator:: Daaloul, Abderrazak
Abstract:: Factors which influence the effectiveness of making early generation selections within bulk populations were investigated. Material utilized included the parents, F₁, and F₂ through F₅ bulk populations resulting from a diallel cross. Information concerning the response of two traits, plant height and grain yield, was obtained for these populations at...

Evaluation of three methods of selection in relation to yield and yield stability in winter wheat (Triticum aestivum Vill., Host)

Creator:: Charoenwatana, Terd, 1937-
Abstract:: The effectiveness of early generation selection for yield and yield stability and the possible identification of superior parental combinations were studied in winter wheat populations representing different levels of genetic diversity. Experimental material for evaluating yield stability consisted of nine bulk and seven modified bulk populations derived from nine parental...

Compensating effects and gene action estimates for the components of grain yield in winter wheat (Triticum aestivum, L. em Thell)

Creator:: Abi-Antoun, Michel
Abstract:: Five winter wheat cultivars and their diallel crosses were evaluated for plant height, harvest index, deading-maturity duration, the components of yield, (spikes per plant, spikelets per spike, kernel weight and kernels per spikelet)and total plant yield. Two diverse locations, Moro, a dryland site (250 mm annually) located in central Oregon...

Nitrate reductase activity and inheritance of grain protein in six barley cultivars (Hordeum vulgare L. and Hordeum distichum)

Creator:: Samphantharak, Krisda
Resource Type:: Dissertation
Full Text:: kernels of six spring barley cultivars grown at East Farm Ex- perimental Station, Corvallis, Oregon, 1972

Influence of chelating agents on genetic recombination of Zea mays L.

Creator:: Ihrke, Charles Albert
Abstract:: Crossover frequencies for seven selected regions on five chromosomes of maize were measured to ascertain the effect of chelating agents on recombination. Ethylenediamine tetraacetic acid, EDTA, and dimethyl sulfoxide, DMSO, were used in three concentrations singly, and in all combinations. Plants heterozygous for for linked genes governing seed and seedling...

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...

Genotype-environment interaction in winter wheat F₁ progeny

Creator:: Peterson, C. J.
Abstract:: Seven winter wheats were evaluated for plant height, the components of yield and yield in a diallel cross at Pendleton, Oregon and Lind, Washington. An additional parent was added to the diallel cross at Pullman, Washington. Two levels of nitrogen and five replications were utilized at each of the locations....
