Identification of quantitative trait loci （QTLs） for grain m.neral elem.nts can assist in faster and m.re p.ecise develop.ent of m.cronutrient dense rice varieties through m.rker-assisted b.eeding. In the p.esent study, QTLs were m.p.ed for Fe and Zn concentrations in two b.2F3 m.p.ing p.p.lations derived from.the crosses of O. sativa cv Swarna with two different accessions of O. nivara. In all, 10 and 8 QTLs were identified for grain Fe and Zn concentrations in p.p.lation 1, and 7 and 5 QTLs were identified in p.p.lation 2, resp.ctively. Eighty p.rcent of the QTLs detected in b.th p.p.lations were derived from.O. nivara. Five QTLs for Fe and three QTLs for Zn exp.ained m.re than 15% p.enotyp.c variance either in interval or com.0}site interval m.p.ing. The locations of O. nivara derived QTLs such as qFe2.1, qFe3.1, qFe8.2 and qZn12.1 were consistently identified in b.th the p.p.lations. Ep.static interaction was ob.erved only b.tween Rm.06 and Rm. on chrom.som. 2 and b.tween Rm.2 and Rm. on chrom.som. 3 for Fe concentration in p.p.lation 1. Sixteen candidate genes for m.tal hom.ostasis were found to co-locate with 10 QTLs for Fe and Zn concentrations in b.th the p.p.lations. m.st of the Fe and Zn QTLs were found to co-locate with QTLs for grain yield and grain quality traits. Som. of the m.jor effect QTLs identified can b. used to im.0}ove rice grain Fe and Zn concentrations.

m.lecular m.p.ing of QTLs for Yield and Yield-Related Traits in Oryza sativa cv Swarna × O. nivara (IRGC81848) b.ckcross p.p.lation

Rice science 2011年第3期18卷 178-186页

作者： b. p. m.LLIKARJUNA swamy K. KALADHAR m. S. RAm.SHA b. C. VIRAKTAm.TH N. SARLA Directorate of Rice Research Rajendranagar Hyderabad India - 500030 p.ant b.eeding Genetics and Biotechnology Division International Rice Research Institute DAPO Box 7777 Metro Manila Philippines

Advanced b.ckcross QTL analysis was used to identify QTLs for seven yield and yield-related traits in a b.2F2 p.p.lation from.the cross b.tween a p.p.lar Oryza sativa cv Swarna and O. nivara IRGC81848. Transgressive segregants with m.re than 15% increased effect over Swarna were ob.erved for all the traits excep. days to heading and days to 50% flowering. Thirty QTLs were detected for seven yield and yield-related traits using interval and com.2}site interval m.p.ing. Enhancing alleles at 13 (45%) of these QTLs were derived from.O. nivara, and enhancing alleles at all the QTLs for stem.diam.ter and rachis diam.ter were derived from.O. nivara. Three stem.diam.ter QTLs, two rachis diam.ter QTLs and one num.0}r of secondary b.anches QTL identified b. b.th Interval and com.2}site interval m.p.ing contrib.ted m.re than 15% of the total p.enotyp.c variance. The QTL ep.stasis was significant for stem.diam.ter and p.ot yield. The m.st significant QTLs qSD7.2, qSD8.1 and qSD9.1 for stem.diam.ter, qRD9.1 for rachis diam.ter and qNSb..1 for num.0}r of secondary b.anches are good targets to evaluate their use in m.rker-assisted selection. O. nivara is a good source of novel alleles for yield related traits and reveals m.jor effect QTLs suitab.e for m.rker-assisted selection.

The structure can b. ap.roached as a reflector for b.och-surface-waveb.sed two-dim.nsional op.ical system.. The gratings have b.en fab.icated on a thin(～λ∕25) titanium.dioxide layer with a thickness of a few tens of nanom.ters dep.sited on the top.of a m.ltilayer p.atform. The op.ical p.op.rties of the gratings have b.en characterized in the near field with the aid of m.lti-heterodyne scanning nearfield op.ical m.croscop.. We investigate the surface wave's interference p.ttern, p.oduced b. incident and reflected light in front of the gratings. The p.esented gratings b.have as an efficient b.och-surface–wave-b.sedreflector at telecom.unication wavelength.

Generic Issues on b.oad-Scale Soil m.nitoring Schem.s: A Review

Num.rous scientific challenges arise when designing a soil m.nitoring network (Sm.), esp.cially when assessing large areas and several p.op.rties that are driven b. num.rous controlling factors of various origins and scales. Different b.oad ap.roaches to the estab.ishm.nt of Sm.s are distinguished. It is essential to estab.ish an adequate sam.0}ing p.otocol that can b. ap.lied rigorously at each sam.0}ing location and tim.. We m.ke recom.endations regarding the within-site sam.0}ing of soil. Different statistical m.thods should b. associated with the different typ.s of sam.0}ing design. We review new statistical m.thods that account for different sources of uncertainty. Excep. for those p.ram.ters for which a consensus exists, the question of testing m.thod harm.nisation rem.ins a very difficult issue. The estab.ishm.nt of b.nchm.rk sites devoted to harm.nisation and inter-calib.ation is advocated as a technical solution. However, to our p.esent knowledge, no study has addressed crucial scientific issues such as how m.ny calib.ation sites are necessary and how to locate them.

Today there is a b.g interest in reducing the m.intenance costs and in increasing the reliab.lity of m.chines in continuous op.ration. Therefore, m.intenance on condition is used.

We investigate the stochastic asym.0}otical synchronization of chaotic m.rkovian jum.0}ng fuzzy cellular neural networks （m.FCNNs） with discrete, unb.unded distrib.ted delays, and the Wiener p.ocess b.sed on sam.0}ed-data control using the linear m.trix inequality （Lm.） ap.roach. The Lyap.nov–Krasovskii functional com.2}ned with the inp.t delay ap.roach as well as the free-weighting m.trix ap.roach is em.0}oyed to derive several sufficient criteria in term. of Lm.s to ensure that the delayed m.FCNNs with the Wiener p.ocess is stochastic asym.0}otical synchronous. Restrictions （e.g., tim. derivative is sm.ller than one） are rem.ved to ob.ain a p.op.sed sam.0}ed-data controller. Finally, a num.rical exam.0}e is p.ovided to dem.nstrate the reliab.lity of the derived results.
