Abstract
The istatistical iinvestigation iof isoybean icrop iin imulti ilocations itrials inamely; iRaipur, iJagdalpur, iKabirdham iand iBemetara idistrict iwas iconducted ion isecondary idata, icollected ifrom iDepartment iof iGenetics iand iPlant iBreeding iin iChhattisgarh iduring ithe iyears i2017-18 iand ihaving imaximum inumber iof igenotypes iin istate.iComparison iof ithe idifferent istability iparameters imethods iviz., iStatistical imethods isuch ias iconventional ianalysis iof ivariance i(ANOVA), istability iparameters, iranking imethod iand imultivariate imethods iwere iidentified ifor ianalysis iof imulti-location itrials.iCombined ianalysis iof ivariance imethod iused ito iidentify ithe iexistence iof iGenotype ix iEnvironmental iInteraction i(GEI) ifrom imultilocation itrials.iThis imethod idescribes ithe imain ieffects iof igenotypes iand ilocation, ieffectively.
Parametric istability ianalysis igivesian ioverall isummary iof ithe iresponse ipatterns iof igenotypes ito ienvironmental idifferent iin ichoose isoybean icrop.iThe iGenotypes iRSC i11-05, iRSC i11-02, iCG iSoya-1(c), iand iJS i97-52(c) iwere ifound ito ibe ithe ihigh iyielding iand imost istable igenotypes iin idifferent ilocation iof iChhattisgarh istate.iThe imultivariate imethod inamely, iprincipal icomponent ianalysis idescribes ithe ipattern iin iG ix iE iInteraction iand ihighlight ithe ibroad iadaptability iand ispecific iadaptability iof igenotypes.iThe ioutput iis igraphical iand ieasy ito iunderstand iand iprovide isupporting ievidence ito iconfirm ithe iresult iof iother imethods.iThe istudy ihas iobviously idemonstrated ithat ithe iAMMI imodel ican isum iup ipatterns iand iconnections iof igenotypes iand ienvironments ieffectively, ijust ias igive ian iimportant iforecast iappraisal ithat imultivariate itechniques iare itoo icomplex ito iprovide ia isimple imeasure iof iyield istability, iwhich ipermits ia ipositioning iof igenotypes.iIt iis iobviously iindicating ithe itransformation iof igenotypes ito ienvironments iand ican ibeiutilized ito idistinguish ithe iprevalent igenotypes iin iconnection iwith ithe ienvironments iand iyears.i
GGE ibi-plots iare ieffective ienough ifor ianalyzing iand ivisualizing ithe ipatterns iof iG ix iE iof ithe isoybean imulti-location idata iwith irespect ito ienvironment iand igenotype ievaluations.iNon-parametric istability ianalysis isimple ito iutilize iand idecipher iand iincrements ior ierasures iof ione ior ia icouple iof igenotypes idon’t icause ia ilot iof ivariety iof iresults.iThus, inumerous iscientists iapplied idistinctive inon-parametric istatistics ito iassess istability.iThe irelationship iof iparametric imeasures iand inon-parametric imeasures, iamong ithemselves, ihave ibeen icalculated.iThese, itherefore, ihave ito ibe ijudged iby ithe irank icorrelation imethod.iThe iresults iof ithe iinvestigation iwould ibe iquite iuseful ito ithe iplant ibreeder iand igeneticists iwho iwould ibe iable ito iselect igenotypes isimultaneously ifor icrop iyield iand icrop iyield istability.iThe iresult ishowed ithat iboth ithe iparametric iand inonparametric imethods igave ia irelatively isimilar iresult.iThe ipresent istudy iwas ian iattempt iin ithis idirection, iaiming ithe icritical iexamination iof istability iin idifferent ilocation iof isoybean icrop iin iChhattisgarh.
