Association between length of grain filling period and grain yield in two wheat populations (Triticum aestivum L. em Thell.)

Creator:: Min, Hwang Kee
Abstract:: The objective of this study was to determine interrelationships among agronomic traits in early and late maturing populations. Two populations were obtained from the crosses, Roussalka/Tesopaco 76 and Yamhill/Aspen. Seeds were space planted with split plot design and nine agronomic traits were observed. In comparative studies between early and late...

Effects of nitrogen applied on wheat straw on winter wheat (Triticum aestivum L.) yields in western Oregon

Creator:: Caputo, John Anthony
Abstract:: Nitrogen deficiency during the winter where winter wheat (Triticum aestivum L.) follows wheat and large amounts of straw have been plowed down has been a factor limiting yield in the Willamette Valley of western Oregon. Field experiments were established to determine if an application of N on the stubble or...

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...

Effect of soil moisture, temperature, bulk density, and texture on emergence of three wheat varieties (Triticum aestivum, L)

Creator:: Halitligil, Mahmut Basri
Abstract:: The effects of soil moisture (-2 to -17 bars), temperature (5 to 20°C), bulk density (0.90 to 1.40 gm/cm³) and texture (Bashaw silty clay and Woodburn silt loam) on germination and seedling emergence of three varieties (Yamhill, Bezostaya, Kirac 66) of wheat (Triticum Aestivum, L.) were evaluated under laboratory and...

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...

Effect of seed protein content on plant growth of barley and wheat

Creator:: Lopez, Arturo
Abstract:: The purpose of this study was to evaluate the effect of seed protein content on plant growth of barley (Hordeum vulgare L. ) and wheat (Triticum aestivum L. ). The effects of nitrogen application on chemical and morphological characteristics of the seed were also studied. Seeds of 'Casbon' winter barley...

Nitrogen uptake by wheat (Triticum aestivum VILL., Host) as a function of root temperature and plant water stress

Creator:: Sepaskhah, Ali Reza
Abstract:: The effect of soil temperature and plant water stress on nitrogen uptake, growth rate and transpiration rate of wheat (Triticum aestivum VILL. , Host) seedlings was studied. A special apparatus for the control of plant water stress and root temperature was used. Leaf area was measured by the air flow...
