Increasing grain yield potential in wheat has been a major target of most breeding programs. Genetic advance has been frequently hindered by negative correlations among yield components that have been often observed in segregant populations and germplasm collections. A tetraploid wheat collection was evaluated in seven environments and genotyped with a 90K SNP assay to identify major and stable...

Genetic improvement of grain yield is always an important objective in wheat breeding. Here, a genome-wide association study was conducted to parse the complex genetic composition of yield-related traits of 105 elite wheat varieties (lines) using the Wheat 90K Illumina iSelect SNP array. Nine yield-related traits, including maximum number of shoots per square meter (MSN), effective number of sp...

Two durum wheat trials were carried out in Mediterranean conditions during 2010/2011 and 2011/2012 growing seasons at Plant Breeding Station-Elvas (Portugal). The experiments were conducted under rainfed conditions however, in 2012, due to extreme drought it was necessary to use artificial irrigation between booting and mid grain filling stage. Thirty durum wheat genotypes were studied and six ...

Fusarium culmorum is one of the most important causal agents of Fusarium head blight (FHB), results in yield and quality reductions and mycotoxin accumulation. It predominates on cereals in North-West of Turkey in cereal growing fields. In this research the aggressiveness among the F. culmorum isolates and reduction on yield was evaluated. Two wheat varieties (Golia and Ceyhan) and 16 isolates ...

Temperature and moisture are essential factors in germination seedling growth. The purpose of this research was to assess the growth wheat (Triticum aestivum L.) seeds under various abiotic stressors. It conducted Agronomy Institute Hungarian University Agriculture Life Sciences, Gödöllő, Hungary. Six distinct temperature levels were used: 5, 10, 15, 20, 25, 30 °C. Stresses drought waterlogging...

Ten durum wheat genotypes were studied in a total of 10 field trials in three different regions of Spain, associated with two latitudes (north and south) under both irrigated and rainfed conditions during the 1998 and 1999 growing seasons. Different technological and commercial quality parameters were studied: thousand kernel weight (TKW), test weight, vitreousness, ash content, protein content...

Thousand kernel weight (TKW) is an important yield component trait affected by the environmental conditions. This study’s objectives were to determine variability for TKW in 32 maize hybrids, sorted four FAO maturity groups (FAO300, 400, 500 and 600), compare 12 environments Croatia (six locations two years) according joint linear regression stability analyses across groups. In general, effects...

Spring barley (Hordeum vulgare L.) is the most important cereal in Iceland and its national breeding program aims to select genotypes adapted environment. A critical step understand adaptation of Nordic material a cool maritime climate assess genotype by environment interaction (GxE). In this study, we evaluated yield thousand-kernel weight (TKW) 32 spring seven Icelandic environments. We appli...

Nine cultivars of winter wheat were compared in organic and conventional crop rotation systems. Bread-making quality was evaluated using three parameters [thousand-kernel weight (TKW) in g, volume weight in g/l, protein content in %]. Grain yield, TKW and protein content of winter wheat in organic cropping system were significantly lower as compared to any intensity in conventional cropping sys...

Chinese wheat mini core collection (262 accessions) was genotyped at 531 microsatellite loci representing a mean marker density of 5.1 cM. One-thousand-kernel weights (TKW) of lines were measured in five trials (three environments in four growing seasons). Structure analysis based on 42 unlinked SSR loci indicated that the materials formed two sub-populations, viz., landraces and modern varieti...
