ABSTRACT
Improving yield is one of the most important targets of sesame breeding. Identifying quantitative trait loci (QTLs) of yield-related traits is a prerequisite for marker-assisted selection (MAS) and QTL/gene cloning. In this study, a BC1 population was developed and genotyped with the specific-locus amplified fragment (SLAF) sequencing technology, and a high-density genetic map was constructed. The map consisted of 13 linkage groups, contained 3528 SLAF markers, and covered a total of 1312.52 cM genetic distance, with an average distance of 0.37 cM between adjacent markers. Based on the map, 46 significant QTLs were identified for seven yield-related traits across three environments. These QTLs distributed on 11 linkage groups, each explaining 2.34-71.41% of the phenotypic variation. Of the QTLs, 23 were stable QTLs that were detected in more than one environment, and 20 were major QTLs that explained more than 10% of the corresponding phenotypic variation in at least one environment. Favorable alleles of 38 QTLs originated from the locally adapted variety, Yuzhi 4; the exotic germplasm line, BS, contributed favorable alleles to only 8 QTLs. The results should provide useful information for future molecular breeding and functional gene cloning.

ABSTRACT
The title compound, [Cu2(C6)H12N4O2)(ClO4)2(C11H6N2O)2].-2C11H6N2O, contains a dinuclear copper(II) complex which lies about a twofold axis at the mid-point of the C-C bond of the oxamide ligand that bridges the two Cu(II) atoms. The Cu...Cu distance is 5.215 (2) A and the Cu atoms have distorted octahedral coordination geometry. Intramolecular N-H...O and N-H...N hydrogen bonds and intermolecular C-H...O hydrogen bonds, together with pi-pi stacking interactions, dominate throughout the crystal structure.
