Povzetek


Šestintrideset genotipov okre je bilo ovrednoteno na osnovi agro-morfoloških in biokemijskih lastnosti v Melkassa Agricultural Research Center, Etiopija, v glavni rastni sezoni 2018 v nepopolnem bločnem poskusu. Predmet raziskave je bil oceniti korelacijo med agro-morfološkimi in biokemijskimi lastnostmi okre s pridelkom plodov in razdeliti korelacijo na neposredne in posredne učinke z multiplo regresijsko analizo. Genotipska korelacija je bila pozitivna in značilna za pridelek plodov na hektar s premerom stebla, višino rastlin, dolžino in širino lista, dolžino plodnega peclja, dolžino plodu, svežo maso plodu, maso stotih semen, pridelkom semen na hektar in vsebnostjo pepela. Fenotipska korelacija je bila pozitivna in značilna za pridelek plodov na hektar s premerom stebla, višino rastlin, številom stranskih poganjkov, dolžino in širino listov, dolžino plodnega peclja, dolžino plodu, svežo maso plodu, številom plodov na rastlino, maso stotih semen, pridelkom semen na hektar, vsebnostjo pepela, maščob in beljakovin. Multipla regresijska analiza je pokazala, da imata sveža masa plodov in pridelek semen na hektar pozitivni neposredni učinek na pridelek plodov na fenotipski in genotipski ravni. Te lastnosti sta izkazali tudi velike do majhne pozitivne posredne učinke skozi druge lastnosti na pridelek plodov na genotipski in fenotipski ravni. Na osnovi te raziskave lahko zaključimo, da obstaja povezava med lastnostmi in pridelkom plodov, ki so najvažnejše pri odbiranju genotipov okre z velikim pridelkom.
