Grain shape is a factor affecting the stigma exsertion rate in rice [PDF]
Frontiers in Plant Science, 2023 Stigma exsertion rate (SER) is an index of outcrossing ability in rice and is a key trait of male sterile lines (MSLs) in hybrid rice. In this study, it was found that the maintainer lines carrying gs3 and gs3/gw8 showed higher SER.

Application of a Novel Quantitative Trait Locus Combination to Improve Grain Shape without Yield Loss in Rice (Oryza sativa L. spp. japonica) [PDF]
Plants, 2023 Grain shape is one of the key factors deciding the yield product and the market value as appearance quality in rice (Oryza sativa L.). The grain shape of japonica cultivars in Korea is quite monotonous because the selection pressure of rice breeding ...

Identification, Fine Mapping and Application of Quantitative Trait Loci for Grain Shape Using Single-Segment Substitution Lines in Rice (Oryza sativa L.) [PDF]
Plants, 2023 Quantitative trait loci (QTLs) and HQTL (heterosis QTLs) for grain shape are two major genetic factors of grain yield and quality in rice (Oryza sativa L.). Although many QTLs for grain shape have been reported, only a few are applied in production.

Discovery and Validation of Grain Shape Loci in U.S. Rice Germplasm Through Haplotype Characterization [PDF]
Frontiers in Genetics, 2022 Rice grain shape is a major determinant of rice market value and the end-use. We mapped quantitative trait loci (QTL) for grain shape traits in a bi-parental recombinant inbred line population (Trenasse/Jupiter) and discovered two major grain length QTLs—

Effects of the grain size and shape on the flow stress: A dislocation dynamics study [PDF]
International Journal of Plasticity, 2019 Dislocation dynamics simulation is used to investigate the effect of grain size and grain shape on the flow stress in model copper grains. We consider grains of 1.25-10 $\mu$m size, three orientations (, and ) and three shapes (cube, plate and needles).

Identification and allele mining of new candidate genes underlying rice grain weight and grain shape by genome-wide association study [PDF]
BMC Genomics, 2021 Background Grain weight and grain shape are important agronomic traits that affect the grain yield potential and grain quality of rice. Both grain weight and grain shape are controlled by multiple genes.

Genome-Wide Association Study of Xian Rice Grain Shape and Weight in Different Environments [PDF]
Plants, 2023 Drought is one of the key environmental factors affecting the growth and yield potential of rice. Grain shape, on the other hand, is an important factor determining the appearance, quality, and yield of rice grains.

Roughness exponents and grain shapes
Physical Review E, 2011 In surfaces with grainy features, the local roughness $w$ shows a crossover at a characteristic length $r_c$, with roughness exponent changing from $\alpha_1\approx 1$ to a smaller $\alpha_2$.

Control of Grain Shape and Size in Rice by Two Functional Alleles of OsPUB3 in Varied Genetic Background [PDF]
Plants, 2022 Grain shape and size are key determinants of grain appearance quality and yield in rice. In our previous study, a grain shape QTL, qGS1-35.2, was fine-mapped using near-isogenic lines (NILs) derived from a cross between Zhenshan 97 (ZS97) and Milyang 46 (

Identification and Pleiotropic Effect Analysis of GSE5 on Rice Chalkiness and Grain Shape [PDF]
Frontiers in Plant Science, 2022 Chalkiness is one of several major restricting factors for the improvement of rice quality. Although many chalkiness-related quantitative trait loci have been mapped, only a small number of genes have been cloned to date.
