Pošlji prispevek (e-pošta) Fenotipska variabilnost in medsebojna povezanost lastnosti genotipov krušne pšenice (Triticum aestivum L.) v severni Etiopiji
Povzetek
Informacije o fenotipski variabilnosti pomagajo pri vzgoji boljših sort. V poskusu z dvema ponovitvama je bilo ovrednotenih 49 genotipov krušne pšenice na območjih Jamma in Geregera z namenom določitve obsega spremenljivosti in medsebojne povezanosti enajstih lastnosti. Analiza variance je pokazala značilne razlike med genotipi (p < 0,01) za vse lastnosti, kar kaže, da je prisotna primerna variabilnost. Največje vrednosti genotipskega koeficienta variabilnosti so bile ugotovljene za dolžino klasa (8,66 %), število cvetočih poganjkov na rastlino (8,4 %), število zrn na klas (6,4 %) in maso1000 semen (6,15 %), kar nakazuje tudi prisotnost precejšnje spremenljivosti teh lastnostih. Raziskava genetskih parametrov je odkrila, da imajo parametri kot so dnevi do klasenja, višina rastlin, dolžina klasa, število zrn na klas in masa 1000 semen zmerno do veliko dednost in genetsko prednost v odstotku poprečja. Zaradi tega bi lahko bila izvedena neposredna selekcija za izboljšanje krušne pšenice na osnovi teh lastnosti. Še več, možen bi bil izbor zgodnejših linij, ki bi pobegnile učinkom podnebnih sprememb. Pridelek zrnja je imel močno in značilno pozitivno korelacijo z maso 1000 semen (rg = 0,395**), biološkim pridelkom (rg = 0,617**) in žetvenim indeksom (rg = 0,731**). Izbor na osnovi teh lastnosti bo najučinkovitejši v bodočih žlahtniteljski programih za izboljšanje pridelka krušne pšenice, ker ima neposredni pozitivni učinek na pridelek zrnja.
