Stigma and Glume Characteristics Synergistically Determine the Stigma Exsertion Rate in Thermo-Photo-Sensitive Genic Male Sterile Wheat.

Wheat hybrids have been widely demonstrated to have remarkable heterosis or hybrid vigor in increasing yield potential and stability since the 1960s. Two-line hybrid wheat can achieve higher yields than local varieties, especially in marginal environments. However, the commercial application of hybrid wheat is hindered by higher seed costs, primarily due to lower yields in hybrid seed production.

Noncentrosymmetric Crystal [CHNO]SiF·HO with Large Birefringence.

Crystals with noncentrosymmetric structures are applied in many fields, but reported compounds have a high probability of forming a centrosymmetric structure. Here, by hydrogen-bonding the π-conjugated [CHNO] cation with the separated [SiF] octahedron, a noncentrosymmetric isoquinoline hexafluorosilicate monohydrate optical crystal of [CHNO]SiF·HO was formed under the regulatory influence of hydrogen bonding. It not only possesses a moderate second harmonic generation response (1.

(CHNO)[BiBr]·2HO and (CHNO)[BiCl]Cl·2HO: Exploring Birefringent Crystals in Hybrid Halide Systems.

In this study, new hybrid birefringent crystals of (CHNO)[BiBr]·2HO and (CHNO)[BiCl]Cl·2HO were successfully synthesized by introducing a new birefringent group [CHNO] by a simple aqueous solution evaporation method. They crystallize in the 2/ space group, and their structure consists mainly of the π-conjugated group [CHNO] and the octahedron centered on Bi. By first-principles calculations, the birefringence response comes from the [CHNO] group with a planar π-conjugated structure.

CHNBrX (X = Cl, Br, NO): Three Excellent Birefringent Crystals with Distinct Optical Anisotropy Regulated by Anions.

A large optical anisotropy is the most important parameter of birefringent crystals. Integrating π-conjugated groups with large polarizable anisotropy into target compounds is a common strategy for constructing brilliant birefringent crystals. However, the key problem is to enhance the density of the birefringence-active units and further arrange them parallelly.

Development of thermo-photo sensitive genic male sterile lines in wheat using doubled haploid breeding.

Background: Two-line hybrid wheat system using thermo-photo sensitive genic male sterility (TPSGMS) is currently the most promising approach for wheat heterosis utilization in China. However, during past 20 years only few TPSGMS lines were developed in hybrid wheat breeding, which has been the main limiting factor to create heterotic hybrids. Application of doubled haploid (DH) breeding provides a useful strategy to efficiently develop practically usable TPSGMS lines.

Optimal similarity norm for electrical tomography based on Bregman divergence.

Electrical Tomography (ET) is an advanced visualization technique, which can reconstruct all targets in an investigated field based on boundary measurements. Since the spatial resolution in the ET process can be greatly affected by the selected similarity norm, different norms may result in different ET time and spatial resolutions. In the tomographic applications nowadays, Bregman divergence (BD) has attracted increasing attention.

Wheat genetic gains for two distinct management schemes in China: An analysis of elite spring type genotypes.

The information collected through multi-environment testing of wheat genotypes not only provides basis to identify promising genotypes but also to ascertain their yield potential and the genetic gains. For this purpose, in the presented study, the data originated from the Yunnan provincial Regional Yield Trials (RYT) conducted during 2006 and 2018 was used. During this period, 107 genotypes were evaluated at 18 locations under Upland Wheat (UW) management scheme, while 116 genotypes were evaluated at 21 locations under Field Wheat (FW) management scheme.
