Abstract Soybean [Glycine max (L.) Merrill] is one of the most important legume crops and its plant height (PH) is one significant quantitative trait closely related to node number (NN) and internode length (IL) on the main stem, which affect yield together. In this study, we used a recombinant inbred line (RIL) derived from a cross between two semi-determinate stem soybean varieties (Dt1Dt1Dt2Dt2), JKK378 and HXW. A consistent QTL named qPH18 simultaneously controlling PH, NN, and IL was identified, in which this region harbors the semi-determinant gene, Dt2. Sequencing of the promoter of Dt2 from JKK378, identified three polymorphisms relative to HXW, including two SNPs and a 18bp Indel. The expression level of Dt2 in qPH18JKK378 group was lower than that in qPH18HXW group, meanwhile, as a downstream gene, the expression of Dt1 from two groups showed a contrary tendency. Transient transfection assay confirmed that the promoter activity of Dt2 from JKK378 is lower compared to HXW. We speculate that the polymorphisms in the two dominant Dt2 promoter caused difference in expression level of Dt2 and its downstream gene Dt1, hence, affect PH, NN, IL, and grain weight per plant without changing stem growth habit. Compared to PH18HXW allele, qPH18JKK378 allele suppresses the expression of Dt2 gene which releases the expression of Dt1, thus promotes plant node number and enhanced grain yield. These results will be helpful for revealing the mechanism underlying the node number and plant height, the soybean materials and molecular marker will facilitate molecule breeding.

The offspring from crosses of 'Cadet' by 'Cadet – Rescue 5A' and 'Winalta' by 'Winalta – Rescue 5A' were studied to obtain information on the inheritance of cold hardiness, winter–spring growth habit, rosette growth habit, height of cold-hardened plants, and length of leaves of hardened plants. The results indicate that a minimum of two loci on chromosome 5A are involved with cold hardening. One locus controls hardiness in part and is tightly linked to the one that controls in part the length of leaves of hardened plants. The other locus is, or it tightly linked to, Vrn1, a winter-spring growth habit locus. This locus may also control part of rosette growth habit. It is postulated that Vrn1 is involved in sensing temperature and in part triggering vernalization, cold hardening, and the development of the rosette growth habit. If so, Vrn1 could code for production of a temperature-sensitive protein, which undergoes conformational changes with changes in temperature.Key words: Triticum aestivum L., cold hardiness, vernalization, rosette growth habit, plant height, leaf length, temperature sensing.
