Grain color formation and analysis of correlated genes by …
网页2023年2月7日 · In this study, the metabolites of wheat grains of three colors (white, blue, and purple) were identified using HPLC-MS/MS. The transcriptome and metabolome were integrated to investigate the mechanism of kernel color formation during maturation of three different colored wheat grains.
Genome-wide association mapping and genomic prediction for kernel color …
网页2022年4月28日 · Three of these seven IWG genes had moderate similarities with R-A1, R-B1, and R-D1, the three genes that control grain color in wheat. We characterized the distribution of kernel color in IWG for the first time, which revealed a broad phenotypic diversity in an elite breeding germplasm.
网页The color of wheat kernels, which varies from light yellow to red brown, is influenced by the presence of red pigmentation in the seed coat and by growing conditions. In a true-breeding culti-var color does not vary and, thus, wheats can be consistently classified as red or white (Evars and Bechtel 1988). These two
Genetics and chemistry of pigments in wheat grain – A review
网页2017年3月1日 · The expression of grain colour varies with the origin of the kernel tissue. In wheat the grain genetically consists of four types of tissue: pericarp, seed coat, embryo and endosperm. The pericarp and seed coat are maternal tissues derived from the carpel and integument, respectively.
Grading Factors of Wheat Kernels Based on Their Physical Properties
网页2017年5月24日 · Kernel colour, shape, size, sphericity, porosity and bulk and specific densities and damages incurred due to heat, insects, molds or sprouting are relevant tests related to wheat kernel properties and quality.
Chapter 8: Inheritance of Quantitative Traits – Crop Genetics
网页Bread wheat is a hexaploid — allopolyploid that contains three slightly different, but similar ancestral genomes (referred to as A, B, and D) in its genome (AABBDD). Depending on the cultivars that Nilsson-Ehle studied, each genome had a single gene that affected kernel color, and each of these loci has a red allele (R) and a white allele (r).
网页Wheat (Triticum aestivum L., and T. compactum Host.) under-goes many environmental stresses that can affect kernel color. For example, excessive rain, frost, insects, and disease can alter the appearance of kernels, causing genetically red kernels to appear white and genetically white kernels to appear red.
Colored kernel production. | Learn Science at Scitable - Nature
网页Wheat kernel color is determined by the action of two genes: gene A and gene B. If either gene is functional, a colored kernel will result. If both genes are not functional, the kernel will...
Wheat Kernel Variety Identification Based on a Large Near …
网页2020年11月9日 · A large spectral dataset of more than 140,000 wheat kernels in 30 varieties was prepared for classification. Feature selection is a critical segment in large spectral data analysis. A novel convolutional neural network-based feature selector (CNN-FS) was proposed to screen out deeply target-related spectral channels.
