INTRODUCTION

The subnetwork dealing witLr the experi-mentation of sunf[ower hybrids and varie-ties has ,completed four biennial icycles. Ttreresults of the first three cycles were publishedin Numb,ers 1 to 5 of this Bull,etin, and theyconstitute an useful gui,Ce for sunfl'ower gro-wers interested in the i,dentific,ation of thebest genotypes for c'ertain specifi,c envirorym,ents, or for determining the optimum biolo-gical par,am,eters of sunflower 'cropping in dif-ferent ,are,as.

In the fourth ,cycle (1982-1983), the experi-mentation was exten'ded to other countri,es,which have'become interested in growing thisoil ,crop. So, the number of participants amoun-ted to 41 reseanch iinrstitutes or stations frorn,29 ,countries.

The particip,ants which provi'ded s'cientific,rigorour: results are listed in Annex 1.

TRIAL No. 2with rnetlium-late cultivars : single (SH) and

calculate'd as the product of the nectar ,contentand its sugar concerr-trâtion. The nectar con-tent was determineC by 'ulsing tiny capillaryglass tubes weighed before and rafter nectarextr'action and sug,ar concentration was esta-blished by means of a portable r,efnactometer.'Ien tubul,ar flowers in the pistillate istage,situated in differ,ent zones of the head wereanalys'ed and trhe mean melliferous index ofe.a'ch entry was estimâted on the ha,sis of tenhe,aC determinations.

Some participants did not succeed in carry-ing out properly the trials due to either lessfavourable climati'c conditions or to certainaccitdenrtal ,causes. The thybrids Seedtec-S-3l 5,Cargill-205 anrd Sunbred-24ï, ,as well as theopen pdllinated variety Pemir were not inclu-ded in network trials in 1982, because theirseed samples rea,ohod the d,estinrations verylate. The hybrid RO-36 w€rs not tested in alllocations in 1983 due to lack of seeds. Somesamples,got mixed up irr,side the package dur-ing the mailing. An irnporbant deficiency ofthe results of 'certain trials was the omissionof data ,con'cerning the seed oil content.

RESULTS AND DISCUSSION

As in the prrevious experimental cycles, tihetrials,carri,ed out in 1982-1983 revealed alarge diversity of the genotype response tothe environmental variation, but some culti-van's exhibited however a retratively constantb'ehaviour i'n most looations, in the two yeiars.In most cas,es, t,he year 1983 was more favou-rable for sunflower nro'duction than 1982.

TRIAL No. 1

Seed yicld ranged greratly from 3.5 q/ha atEl Kthemis, Alg,eria, to 44.6 q/ha gt Osijek,Yugoslavia (Ta'ble 1). The highest v€lues wererecor'ded in South-East of Europe (Romania,Hungary and Yugoslavia) where sc,me hybridssurpassed the level of 40 q/rha, especially in1983, and wher'e the annual trial means r.angdfrom 21.3 ,q/ha at Novi Sad, Yugoslavia, in1982 when suniflower was badly dam'aged byPhomopsis sp., to 3?.5 q/ha at Fulndulea, RÛ-mania in the same y.ear. GooC results ,al'sowere obtained in the Feder,al Republi,c of Ger-mlany, Czechoslovakia and Iran where the an-nual trial means rang'ed frorri 2?.5 q/ha to33.9 q/tha. In the other locations, the annualseed yield Èrr.eans of the whole set of cultivarswere mudh lower, varyinrg from 5.2 q/ha inAlgeria to 28.2 q/ha inl Egypt rand thus con-tributing to the diminution of the general trialm'ean to 23.8 q/ha.

Judging from thc standpoint of th,e generalseed yield meÊn, 12 ,hybri'ds were significantlydifferent from the early open poilinated varietyCerne,anka, btit the 'enûire group of these hy-brids, although rânging from 26.3 q/ha (RO-25)to 23.2 q/ha (G 19/77), was statistically similar.

The genotypes under study have representedlhe latest releases of sunflower br,eeders froml3ulgaria, Fran.oe, F. R. Germany, Hungary,Romania, Spain, U.S.A., and Yugo,slavia.

The experimental design for both trials rvasthe randomized hlocks with 5 replications. Theentry ran,Comization for ea,ch location wasestablish'ed by the F.A.O. Crop and GrasslandProduction Service. The plot size was determi-ned taking into account th,at,-after dis,cardirrgthe bord,ers (1 or 2 marginal rows and 2 frontalplanls per each row), a minimum of B0 plantsper plot be harvested. T,he plant populationand other cultural practices were adapted tothe local con'ditions. Some trials were ,conhducte'd und,er irrigation, but most in dryland.

Alor,ig with seed samples, field books ândinstru,ctions were provid,ed for ea,ch trial, inorder to facilitate the uniform data ,collectionand evaluation. The interpretation of the ex-perim,ental data was perforrnl:d on the basisof the ,analysis of variance, p,articularly forseed yield and oil ,content.

Resi,stance to ,Ciseases and tolerance to 'un-tavourabl,e environmental condition,s were esti-mated only in the fieid.

In comparison with th,e former experim'entalcycles, new tr:ai'ts were studied su,ch as pollenself*f,ertility anfd the melliferous value. Thedegree of self-fertility was defined as the ratiobetween the mean number of filled seeds or1the bagged heads and the mean number offillecl seeds on the open-pollinated heads. Arc-sine transformation of data was.used orior tostatistical analysis. The melliferous index was

Ilowever, in different ,countries and yeans cer-tain hybrids were better discriminated, indi-cating their environmental spe,cifi,c a'dapta-bility.

Oil content in dried seeds varied also greatlyfrom location to location and from y,ear toyear. Data from Table 2 poiqb out that thecultivars of this trial were sur:eriolfrom theoi1 content standpoint to those studied in theprevious network trials, the annual trial meansbeing rr'igtr,er trhan 500/s in 10 'aases. Three ,hy-brids (RO-25, RO-?0 and NS-H-4) were sig-nifi'cantly different from the rest of 12 culti-'nars, with a general rnean oi1 content of '51t70,480/6 and 480/6 r,espectively.

The tested hybrids $rere generally later andtaller than the opeq pollinated variety Cer-neanka, known as one of dhe ,earl.iest andshort'est cultivar (Table 3). Some ,of tkrem hadlarger seed,s, sup,erior values of volume weight,arrd a better resistance to [odging.

TRIAL No. 2

As in the 'case of Tri,al No. 1, ,s. rgreat varia-tion has ,been noticed amonrg the mediurn-latecultiva.ns of Trial No. 2, as a dunction o,f [o,ca-tions and yeârs._ Seed yield ranged from 2.0 q/kn at Elvas,P,ortugal, to 48.6 q/ha at, Osijek, Yugoslavie.(Table 6). The highest rannu,al triaL means wer.ete,corded at Szegerd, Hungary and Osijek, yugo-.slavia, in 1983 (40.8 and 40.6 q/Lra respectively)and the ,lowest at Islamabad. pakistan (b.gkg/ha). High average yields, over B0 q/ha, wèrealso obtained in Romania, Austria, Israel (1 gBB)and Argentina (Miramar). With the exception ofPakistan, very poor seed yields were recordedin Argentina (Manfredi), Italy (Pisa), Spain(Sevilla), Portugal (Elvas), U.S.A. (Fargo, N.D.).

* Duncan's multiple range test. Means with the sage letter are not significantly different.

The general mean of Trial No. 2 v/'as quiteclose lto that of Tbial No. I (25.4 q/ha as

agiainst 23,8 q/Lra), indi'cating that rthe diffe-rence in m,aturity of the two types of sunfflower cultivars wâs not so great as to 'deter-mine significant differ,ences in seed yield.

Statistically, th,e mrajority of cultivars fellin the sam,e group âs fâr 'as th€ general seddyield m'ean is concerned. Thus, 14 entries, in-'cl,u,ding 13 rhybri'ds and the opeq ollinatdvariety Peredovik \ÀIere llIa,otically sirnilar ac-cording to Duncan's multiple ûan'ge test, a1t-

t2

hough their average seed yiel'd ranged from26.7- q/:ha (RO-44) to 24.0 q/ha (HB-763). Un'dermore limited environments, certain hybridswere however better diffenentiate'd, accordingto tùreir ;sp,eci'fi,c adaptebility.

A similar r'e'action was notised with respectto oil content (Table 7). So, tl}r,e general meanof 13 cultivar:s fell in the s,ame statlstic group,although ranging from 47.80/6 to 45.00/s andonly two hybrids werre significantly different,the hybrid RO-44 with tlhe hig'hest oil content(50.2%) and the hybrid Stauffer-3l01 withthe lowest oil content (41.6%).

RÉSULTATS DU QUATRIÈME CYCLEEXPÉRIMENTAL AVEC DES CULTIVARS

DE TOURNESOL (1982-1983)

Résumé

Un nouveau cycle biennal d'expérimentation, con-tenant t6 cultivars et hybrides de tournesol rdemi-précoces et précoces, et 20r demi-tandifs, a été effec-tué en 32 localités, ,dont 20 localités de 13 pay.seuropéens et 12 localités de g pays hors de t,Europe.

Les conditions de milieu extrêmement di,fférentesont déterminé une large variation de la réaction desgénotypes de tournesol, tant concernant le rende-ment en semences et la teneur en huile. oue lesautres caractéristiques agronomiques.

M.algré cette importante variation, les valeurs mo-.vennes pour toutes les localités ont été, pour Ia plu-part des cas, similaires du point de vue statistique,en suggérant I'existence de certaines ressemblancesgénétiques des cultivars testés. Certains hybrides detournesol se sont, toutefois, différenciés dans le cadrede certaines zones plus restrelntes, en permettantaux cultivateurs d'identifier les génotypes adéquats,Ies mieux adaptés.

RESULTADOS DEL CUARTO CICLOEXPERIMENTAL CON CUI-TIVARES DE GIRASOL

(1982_1983)

Res{nnenIJn nuevo ciclo bienal de experimentaci6n, com-

prendiendo 16 variedades e hirbridos de girasol semi-preooc'es y 20 sernitardfos, se ùra efectuado en 82 loca-lid'ades de 13 paises europeos y 12 localfidades de!t paises fuera de Europa.

Las condici,ones de medio extremadarnente dife-rentes han determinado una gran variacfon de losgenotipos de girasol tanto en cunato a la producciônde semill,as y del contenido en aceite, como a otrascaracteristi cas agron6micas.

A pesar de esta gran variaci6n, los valores mediospara todas las localidadesr dueron en lâ miayoria idelos casos similares desde el punto de visrta esta-distico, sugeriendo la existencia de ciertes semblanzasF,enéticas de los cultivares testados" Sin embargo,algunos de los hibridos de girasol se diferenciaronmeior dentro de unas zonas mâs restrinEidas. ber-rnitiendo a los cultivadores i.dentificar loJ genotiposcorrespondientes, los mejores,adaptados.

CONCLUSIONS

The ,extremely different environmenta.l con-ditions 'determined, as excepted, a great varia-tion in the rrespons,e of suhflo\Mer g,enotypes,both for seed yi.eld and oil content, as well ,asfor other êgron,omic ch,aracteristics. Notwith-standing this great variation, th,e rnean vâlu,esfor all |environments were statisticallv similarin m,ost ,cases, suggesting â possiblé geneticresemblân,oe of the aultivars under testing.

Certain sunflower lrybrids were howeverb,etter differentiat,e,d within ,some limited ,areas,allcrwing growers to identify the best adaptedand suitable genotypes.
