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...

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...

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,...

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...

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...

Effect of row spacings, seeding rates and nitrogen fertilizer rates on the agronomic performance of Yamhill and Hysolop wheat (Triticum aestivum L.)

Creator:: Chemli, Mohamed
Abstract:: The response of two newly released cultivars of winter wheat when grown under different row spacings, seeding rates and nitrogen levels were investigated. Measurements made included grain yield, tiller number per unit area, plant height, 300 kernel weight, bushel weight and protein content of the grain. Hyslop and Yamhill cultivars...

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...

Methods of evaluation, effects of intermating and results of one cycle of S₁ family recurrent selection in barley

Creator:: Mareck, James
Abstract:: The focus of this study was to determine if S₁ family recurrent selection might be successfully used for barley improvement. Objectives were: 1) to identify suitable methods of evaluating grain yield in small plots, 2) to study the effects of intermating on mean values and variances of selected agronomic characters,...
