An incomplete diallel cross study comprising of seven bread wheat (Triticum aestivum L.) cultivars was carried out with parents and F1 progeny to determine heterosis, combining ability, gene action, and correlations for plant height and its components. The results showed that heterosis and heterobeltiosis occurred in plant height, spike length, peduncle length, length of the second internode fr...

Winter wheat, (cv. Consort) was inoculated with three isolates of either Oculimacula yallundae or O. acuformis to determine the effect of eyespot caused by each species on yield and lodging resistance of winter wheat. Plants were visually assessed for disease incidence and severity, and pathogen DNA was quantified at GS 33 and GS 60. At early milk development of the crop (GS 72), 900 main shoot...

This experiment was conducted at Debre Zeit and Akaki during 2004-2005 cropping season on F2-derived F4 bulk families of three crosses, viz, DZ-01-974 x DZ-01-2786, DZ-01-974 x DZ-Cr-37 and Alba x Kaye Murri. To estimate the correlations and path coefficients between yield and yield components, 63 F4 families were taken randomly from each of the three crosses. The 189 F4 families, five parents ...

Lodging affects grain quality and yield in wheat (Triticum aestivum L.) is difficult to breed for because its sporadic incidence laborious protocols measure lodging traits. Thus, developing molecular markers these traits can increase selection efficiency breeding programs. The aim of this article identify quantitative trait loci (QTL) associated with stem/anchorage strength leverage (lodging tr...

Intermediate wheatgrass [IWG; Thinopyrum intermedium (Host) Barkworth & D.R. Dewey] is a perennial cereal and forage crop marketed for its grain, Kernza. Lodging, which correlated with plant height, can reduce IWG grain yield. Our goal was to determine the effects of growth regulator trinexapac-ethyl (TE) application rate; harvest timing; N rate on lodging, aboveground biomass, yield, index. Th...

in order to select and release of bastan a new cultivar of foxtail millet, after preliminary selections in small millet germplasm a research was carried during 1997-2003 in karaj, golestan and dezful. during these years production potential of 10 foxtail millet genotypes was determined in a randomized complete block design for 3 years. the different characteristics include, leaf size, stem diam...

Societal Impact Statement Crop diversification is considered key to ensuring agricultural sustainability and food security. Tef (Eragrostis tef (Zucc.) Trotter) a cereal crop grown mainly in Ethiopia, where it thrives wide range of environments, including stress-prone habitats. It promising new gaining popularity cultivation research worldwide. Lodging, the greatest factor limiting productivity...

from the plants nutrition view point, silicon has not been recognized as an essential element but its useful effects on growth and development of many plants have been reported. in order to study the effect of application of different silicon on the yield component of wheat, an experiment was conducted in the city torbat heidarieh located in razavi khorasan province. the experiment was performe...

plant growth regulators (pgrs) are widely used for lodging control in winter wheat (triticum aestivum l.) grown at high n rates. although the introduction of semi-dwarf wheat cultivars had largely solved the problem of lodging, evidence was already accumu-lating that the timely application of a growth retardant such as chlormequat (ccc) or ethephon could increase the grain yield of wheat, by th...
