“…On the basis of genetic effects and gene heritability, HSR is inferred to be a complex quantitative trait regulated by the additive-epistatic effects of three major genes as well as polygenes. Additive effects predominated over all other types of genetic effects, and, as in previous studies, higher heritabilities of the trait were recorded with respect to major genes than polygenes [ 5 – 6 ]. HSR is primarily controlled by hereditable factors: more than 80.0% of the phenotypic variation among DH populations is controlled by three major genes and polygenes, with environmental factors having a minimal influence (< 10.0%).…”

“…HSR evaluation method is the basis of further related research. Days to splitting after maturity or head splitting rate was most adopted as resistance evaluation criteria by relevant previous studies [ 5 – 6 ]. Although they are simple and intuitive, the characteristic of HSR can't be fully embody for different split layers and size.…”

“…Few relevant genetic analyses have been conducted, however, and previous genetic studies of HSR inheritance have focused only on HSR as a polygenic system and ignored the effect of individual genes [ 5 – 6 ]. To ensure the precision of genetic analyses for quantitative traits, the use of a segregating population with more than 100 individuals and several replications is required.…”

Head splitting resistance (HSR) in cabbage is an important trait closely related to both quality and yield of head. However, the genetic control of this trait remains unclear. In this study, a doubled haploid (DH) population derived from an intra-cross between head splitting-susceptible inbred cabbage line 79–156 and resistant line 96–100 was obtained and used to analyze inheritance and detect quantitative trait loci (QTLs) for HSR using a mixed major gene/polygene inheritance analysis and QTL mapping. HSR can be attributed to additive-epistatic effects of three major gene pairs combined with those of polygenes. Negative and significant correlations were also detected between head Hsr and head vertical diameter (Hvd), head transverse diameter (Htd) and head weight (Hw). Using the DH population, a genetic map was constructed with simple sequence repeat (SSR) and insertion–deletion (InDel) markers, with a total length of 1065.9 cM and average interval length of 4.4 cM between adjacent markers. Nine QTLs for HSR were located on chromosomes C3, C4, C7, and C9 based on 2 years of phenotypic data using both multiple-QTL mapping and inclusive composite interval mapping. The identified QTLs collectively explained 39.4 to 59.1% of phenotypic variation. Three major QTLs (Hsr 3.2, 4.2, 9.2) showing a relatively larger effect were robustly detected in different years or with different mapping methods. The HSR trait was shown to have complex genetic mechanisms. Results from QTL mapping and classical genetic analysis were consistent. The QTLs obtained in this study should be useful for molecular marker-assisted selection in cabbage breeding and provide a foundation for further research on HSR genetic regulation.

“…Resistance to early bolting, which in practice is tolerance to head splitting and, further, a tolerance to abiotic factors, is controlled by three genes acting additively with partial dominance for early bolting (Dickson and Wallace 1986) plus modifying factors (Chiang et al 1993). Chiang (1972) reported that the narrow-sense heritability for bolting was 47%. Since the genes for this trait act additively, late bolting is partly recessive and the heritability is not low, signi®cant selection response was expected and achieved ( Table 1).…”

Mass selection with controlled pollination for heading, resistance to early bolting, fewer frame leaves relative to head size and few cover leaves, was applied for three cycles in four Greek open‐pollinating populations (OPPs) of cabbage in nil‐competition conditions (honeycomb method). The cycle 0 OPPs with their respective cycle 3 OPPs were tested under competition conditions (growers density), in two successive years, to assess the selection response for heading, resistance to early bolting, number of cover leaves and yield. In most cases, the selection response was significant at P = 0.01 or even at P = 0.001. For example, the mean increase of yield estimated over all OPPs across 2 years was 36%, without any undesirable changes in dry matter and soluble solids contents.

High-resolution X-ray powder diffraction with synchrotron radiation coupled with Rietveld analysis has been used recently as one of the best way to obtain structural information from a powder specimen. Molecular and crystal structures of the galvinoxyl radical (Cz9~I02) were studied by means of powder diffraction using NSLS (National Synchrotron Light Source) with f.. =1.5855 Aand a rotating anode with Cu Ka radiation. The space group of the crystal is C 2/e with refined lattice parameters a =23.786(1), b = 10.8611(4),c= 10.6766(4) A,~=106.634(3)",Z =4. The peak shape was fitted with a pseudo-Voigtprofile function. The preferred orientation is along the <01i> direction of the needle-like crystals. Final refinements were converged to give agreement indices Rp 0.08 and 0.17 respectively for synchrotron radiation and rotating anode data. The fitting of \he peak profile and refined parameters from the synchrotron radiation data are significantly better than those from rotating anode data. No significant ditferences are found between single crystal results and those in this work. This work provides evidence that powder diffraction, especially with synchrotron radiation, could be used as one means of structural analysis even for such a weakly scattering organic material.
