Variation in flowering time and response to overwintering has been exploited to breed brassica vegetables that can be harvested year-round. Our knowledge of flowering time control now enables the investigation of the molecular basis of this important variation. Here, we show that a major determinant of heading date variation in Brassica oleracea is from variation in vernalization response throu...
Important agronomical traits in perennial ryegrass (Lolium perenne) breeding programs such as winter survival and heading date, are quantitative traits that are generally controlled by multiple loci. Individually, these loci have relatively small effects. The aim of this study was to develop a candidate gene based Illumina GoldenGate 1,536-plex assay, containing single nucleotide polymorphism m...
Low temperature or cold stress is one of the major abiotic stresses for rice production and productivity in temperate rice-growing regions as well as in tropical highlands worldwide. Low temperature at the reproductive stage causes high sterility and decreases production of elite rice cultivars. In this study, we used F7–8 recombinant inbred lines (RILs) which had cold-tolerance genes/quantitat...
In this paper, the fracture behavior of ML15 cold heading steel was investigated based on ductile theory. Smooth and notched bar, flat grooved tensile–shear mixed plate specimens were designed, tensile tests carried out to examine mechanism ML15. The micromechanical characteristics surfaces different studied by performing scanning electron microscopy. results showed that under stress states mic...
In order to evaluate the productivity potential of some bread wheat varieties and promising lines under no-till rainfed condition two different on-farm trials were conducted in cold (Sonqor) and warm (Sarpol-e Zahab) regions of Kermanshah province during 2017-18 cropping season. In the cold condition, 12 winter genotypes and in the warm condition 32 spring genotypes were evaluated for grain ...
In order to analyze the evolution of inclusions in cold heading steel SWRCH35K during steelmaking process, a systematic sampling processes plant was carried out. Both SEM-EDS and image processing software Image-Pro-Plus6.0 were employed chemical composition, morphology, quantity size non-metal samples. The results show that from BOF tapping continuous casting tundish, composition changes Al2O3 ...
