Povzetek


Poskus je potekal na 202 novih lokalnih zvrsteh čičerke (Cicer arietinum L.) z dvema preiskusoma za ovrednotenje neposredne in posredne povezave učinkov različnih lastnosti na pridelek. Poskus je bil izveden leta 2016 v krajih Sirinka in Jari v Etiopiji v razmerah brez namakanja kot nepopolni bločni poskus s tremi ponovitvami. Zbrani so bili podatki o pridelku in z njim povezanimi lastnostmi. Analiza variance je pokazala zelo značilne razlike med genotipi. Povezava med pridelkom z biomaso in žetvenim indeksom je bila pozitivna in zelo značilna na genotipski in fenotipski ravni. Dodatno je bila povezava pridelka pozitivna z lastnostmi kot so obdobje polnjenja strokov, višina rastlin, število sekundarnih poganjkov in masa stotih semen a nestatistično značina, ne na genotipski niti na fenotipski ravni. Analiza povezav na genotipski ravni je pokazala, da ima 15 znakov (lastnosti) kot so biomasa, žetveni indeks, dolžina stroka, število dni do nastavka strokov, obdobje polnjena strokov, širina nadzemnega dela rastlin, število primarnih in sekundarnih stranskih pogankov in število strokov na rastlino pozitivni in neposredni vpliv na pridelek semena. Tudi lastnosti kot so število dni do cvetenja, višina rastlin in masa stotih semen so imele pozitivne genetske povezave s pridelkom zrnja. Nasplošno je povezava med znaki povezana s povezavo med posameznimi znaki odkrila, da sta imela biomasa in žetveni indeks neposredno povezavo s pridelkom semena.
