Validation of candidate gene-based markers and identification of novel loci for thousand-grain weight in spring bread wheat
Increased thousand-grain weight (TGW) is an important breeding target for indirectly improving grain yield (GY). Fourteen reported candidate genes known to enhance TGW were evaluated in two independent and existing datasets ...
A wheat chromosome 5AL region confers seedling resistance to both tan spot and Septoria nodorum blotch in two mapping populations
Tan spot (TS) and Septoria nodorum blotch (SNB), caused by Pyrenophora tritici-repentis and Parastagonospora nodorum, respectively, are important fungal leaf-spotting diseases of wheat that cause significant losses in grain ...
Results of the 1st International Heat Stress Genotype Experiment
Fischer (1989) summarized the detrimental effects of high temperature on wheat growth as follows: Yield reduction can occur at temperatures above a mean as low as 150C, with the spike and grain growth phases being especially ...
Increasing the yield potential of irrigated bread wheat: basis for physiological research at CIMMYT
Yield potential (YP) is defined as the "yield of a cultivar grown in environments to which it is adapted when nutrients and water are nonlimiting, and when pests, diseases, weeds, lodging, and other stresses are effectively ...
Photosynthetic characteristics of synthetic bread wheats
In the process of genetic improvement of bread wheat, photosynthetic rate per unit leaf area has decreased significantly from the maximum photosynthetic rate (Pmax) of the crop's diploid ancestors (donors of the A, B, and ...
Breeding resistance to yellow (stripe) rust in wheat
The information contained in this paper is a precis of the PhD thesis of Dr. H.P. Bimb. Since yellow (stripe) rust has recently reared its head in West and South Asia, the rapid publication of this Wheat Program Special ...
CIMMYT/NARS Consultancy on ME1 bread wheat breeding: 4-7 April, 1995 Cd. Obregon, Sonora, Mexico
Through the mechanism of internally managed external reviews (IMERS), all activities of the Wheat Program were reviewed in the period 1990-1994. In general, this was a satisfactory exercise, except that we felt NARS input ...
Cultural practices and varietal preferences for durum wheat by farmers of Ada, Lume and Gimbichu Weredas of Ethiopia
(CIMMYT; Alemaya University of Agriculture, 1994)
A survey of 144 fanners was undertaken in Ada, Lume and Gimbichu Weredas to assess fanners' practices in durum wheat production; and to identify the durum wheat varieties they grow and the quality characteristics they seek ...
The septoria diseases of wheat: concepts and methods of disease management
This manual summarizes the more pertinent scientific reports on managing the two major septoria pathogens. Topics include the biology of the fungi, infection process, collection an handling of infected material, isolation ...
Monitoring wheat varietal diffusion in the irrigated Punjab: Results from 1987-88
(CIMMYT; PARC, 1988)
Recommended wheat varieties play a significant role in increasing wheat productivity. Wheat breeders at different research institutes in Pakistan are continuously working to develop rust and disease resistant varleties. ...
