Abstract

Research on the flowering habit of rapeseed is important for the selection of varieties adapted to specific ecological environments. Here, quantitative trait loci (QTL) for the days-to-flowering trait were identified using a doubled haploid population of 178 lines derived from a cross between the winter type SGDH284 and the semi-winter type 158A. A linkage map encompassing 3268.01 cM was constructed using 2777 bin markers obtained from next-generation sequencing. The preliminary mapping results revealed 56 QTLs for the days to flowering in the six replicates in the three environments. Twelve consensus QTLs were identified by a QTL meta-analysis, two of which (cqDTF-C02 and cqDTF-C06) were designated as major QTLs. Based on the micro-collinearity of the target regions between B. napus and Arabidopsis, four genes possibly related to flowering time were identified in the cqDTF-C02 interval, and only one gene possibly related to flowering time was identified in the cqDTF-C06 interval. A tightly linked insertion–deletion marker for the cqFT-C02 locus was developed. These findings will aid the breeding of early maturing B. napus varieties.

Abstract

A new type of broadband piezoelectric ceramic transducer is developed and analyzed. The transducer is composed of two radial enhanced composite vibrators with different resonance frequencies stacked along the axial direction. Each vibrator consists of a piezoelectric ceramic stack polarized in the thickness direction and a metal tube, and they are connected and excited to vibrate in the radial direction. On the basis of the radial vibrations of the piezoelectric ceramic thin ring and the metal tube, the electromechanical equivalent circuit of the transducer is derived and the input impedance of the transducer is obtained. The relationship between the resonance frequency and the geometrical dimensions of the transducer is analyzed. The new type of transducer is simulated using the ANSYS software. The simulated resonance frequencies of the transducer are in good agreement with the theoretical results. The transducer exhibits broadband characteristics because of the double stacking of vibrators with different resonance frequencies, and the transducer can be driven under high power because of its radial enhanced composite structure.
