Prediction of wheat phenology facilitates the selection of cultivars with specific adaptations to a particular environment. However, while QTL analysis for heading date can identify major genes controlling phenology, the results are limited to the environments and genotypes tested. Moreover, while ecophysiological models allow accurate predictions in new environments, they may require substanti...
Agricultural crop species represent a negligible part of the existing biodiversity. Over 50 percent of the daily global requirement of proteins and calories is met by just three crops – maize, wheat and rice (FAO, 1996) – and only 150 crops are commercialised on a significant global scale. On the other hand, ethnobotanic surveys indicate that, worldwide, more than 7,000 plant species are cultiv...
BACKGROUND Bread wheat (Triticum aestivum L.) is one of the most important crops worldwide and its production faces pressing challenges, the solution of which demands genome information. However, the large, highly repetitive hexaploid wheat genome has been considered intractable to standard sequencing approaches. Therefore the International Wheat Genome Sequencing Consortium (IWGSC) proposes to...
Ancient and modern 183 varieties of winter 23 spring types development bread wheat (Triticum aestivum L.) selected Ukrainian state institutions private companies are characterized by alleles Ppd-D1, Ppd-B1, Ppd-A1 genes. Allele-specific molecular markers, proposed in the scientific literature, were used to identify carriers Ppd-D1a, Ppd-D1b, Ppd-D1c, Ppd-D1d, Ppd-B1a, Ppd-B1c, Ppd-A1b alleles. ...
Acrylamide is a neurotoxin and probable carcinogen formed as processing contaminant during baking production of different foodstuffs, including bread products. The amino acid asparagine the limiting substrate in Maillard reaction that produces acrylamide, so developing wheat (Triticum aestivum L.) cultivars with low free concentrations grain promising approach to reduce dietary acrylamide expos...
Extremely short, high yielding cultivars of all crop plants are needed to optimize the food production of bioregenerative life support systems in space. In the early 1980's, we examined over a thousand wheat genotypes from the world germplasm collection in search of genotypes with appropriate characteristics for food production in space. Here we report the results of 12 years of hybridization a...
Genetic differences among major types of wheat are well characterized; however, little is known about how these distinctions affect the small molecule profile of the wheat seed. Ethanol/water (65% v/v) extracts of seed from 45 wheat lines representing 3 genetically distinct classes, tetraploid durum (Triticum turgidum subspecies durum) (DW) and hexaploid hard and soft bread wheat (T. aestivum s...
Abstract Smallholder farmers in Ethiopia are involved multiple seed sources to access bread wheat seed. The present study was conducted Baso Liben district, northwest Ethiopia, with the objectives of identifying existing sources, factors affecting use improved seed, and assessing practitioners’ (farmers experts) suggestions improve sources. Both quantitative qualitative data were collected from...
