Abstract

V sklopu magistrskega dela smo v Slovenski rastlinski genski banki Kmetijskega inštituta Slovenije, s pomočjo morfometričnih parametrov ovrednotili zbirki genskih virov navadnega (Phaseolus vulgaris L.) in turškega fižola (Phaseolus coccineus L.). S predpisanimi deskriptorji (UPOV, CPVO, IBPGR, Phaselieu) za semena vrst Phaseolus sp., smo skupno okarakterizirati 953 akcesij navadnega in 47 akcesij turškega fižola. Pri vsaki akcesiji smo na 10 polno razvitih in nepoškodovanih semenih vrednotili 6 kvantitativnih (numeričnih) parametrov: dolžino semena; širino semena; višino semena; razmerje dolžina/višina; razmerje višina/širina; in maso 100 oz. 10 semen. Pri navadnem fižolu smo določili maso na 100, pri turškem pa na 10 semenih. V nadaljevanju smo semena vrednotili z 8 kvalitativnimi (opisnimi) parametri: barva semena; število barv na semenu; primarna barva semena; sekundarna barva semena; razporeditev sekundarne barve na semenu; ožiljenost semena; oblika semena; ter barva in vzorec na plašču semena. Za vsako akcesijo smo posneli vzorčno fotografijo visoke ločljivosti. Na osnovi rezultatov 6 numeričnih parametrov smo za akcesije navadnega fižola pojasnili njihov geografski izvor. Pri vrednotenju turškega fižola, so se akcesije na osnovi 6 numeričnih parametrov najbolj razlikovale v masi 10 semen. Na osnovi rezultatov 8 opisnih parametrov, sta se pri navadnem in turškem fižolu izoblikovali dve skupini. Prva je zajemala akcesije s primarno in sekundarno barvo, druga pa semena le s primarno barvo svetlih ali temnih odtenkov. Na osnovi vseh 14 morfometričnih parametrov, sta se pri obeh zbirkah genskih virov fižola izoblikovali dve skupini. Prva skupina je zajemala akcesije Andskega in druga Srednje Ameriškega izvora.

Secondary title: Evaluation of common (Phaseolus vulgaris L.) and runner (Phaseolus coccineus L.) bean genetic resources using morphometric parameters
Secondary abstract: Genetic resources of common (Phaseolus vulgaris L.) and runner bean (Phaseolus coccineus L.) from the Slovene plant genetic bank at the Agricultural Institute of Slovenia were evaluated using morphometric parameters. Several Phaseolus spp. seed descriptors (UPOV, CPVO, IBPGR, Phaselieu) were used to characterize 953 accessions of common and 47 accessions of runner bean accessions. Ten fully developed and undamaged seeds for each accession were evaluated using 6 quantitative (numerical) parameters: seed length; seed thickness; seed width; length/width ratio; width/ thickness ratio; and 100 or 10 seeds weight. For common bean accessions 100 seeds weight and for runner bean accessions 10 seeds weight was measured. In addition, seeds were evaluated using 8 qualitative (descriptive) parameters: seed colour; number of colours on seed; primary seed colour; secondary seed colour; distribution of secondary seed colour; seed veining; seed shape; and colour and the pattern on the seed coat. For each accession high resolution photography was recorded. On the basis of 6 numerical parameters the geographical origin for the common bean accessions was explained. Of the 6 numerical parameters used, 10 seeds weight was the most important parameter to distinguish runner bean accessions. Based on 8 descriptive parameters, two groups were formed in each of the bean collections. The first group included seeds with primary and secondary colour, the second group represents seeds with primary colour of different light or dark shades. On the basis of all 14 morphometric parameters two groups could be clearly distinguished in both collections. The first group included accessions from Andean and second from Mesoamerican origin.
