POPULATION STRUCTURE OF CHINESE SOUTHWEST WHEAT GERMPLASMS RESISTANT TO STRIPE RUST AND POWDERY MILDEW USING THE DART-SEQ TECHNIQUE

Population structure of Chinese southwest wheat germplasms resistant to stripe rust and powdery mildew using the DArT-seq technique

ABSTRACT: Understanding genetic variability in existing wheat accessions is critical for collection, conservation and use of wheat germplasms.In this study, 138 Chinese southwest wheat accessions were investigated by genotyping using two resistance gene makers (Pm21 and Yr26) and DArT-seq technique.Finally, about 50% cultivars (lines) amplified the

Research on Thermal Error Modeling of Motorized Spindle Based on BP Neural Network Optimized by Beetle Antennae Search Algorithm

High-speed motorized spindle heating will produce thermal error, which is an important factor affecting the machining accuracy of machine tools.The thermal error model of high-speed motorized spindles can compensate for thermal error and improve machining accuracy effectively.In order to confirm the high precision thermal error model, Beetle antenn

Vector dark matter from a gauged SU(2) symmetry

Abstract We propose a scenario of currys dyson dc40 dark sector described by a hidden SU(2) gauge symmetry which is broken by a vacuum expectation value(VEV) of a scalar multiplet.We discuss a general mass relation among SU(2) gauge bosons after spontaneous symmetry breaking which is determined by weight of gauge group representation associated wit
