Korelacijska, regresijska in klasterska analiza dejavnikov, ki vplivajo na pridelek in ekspanzijske lastnosti pokovke (Zea mays L. everta) v agroekosistemih prehodne savane in deževnega gozda Nigerije
Povzetek
Informacije o povezanosti genetskih in agronomskih lastnosti poljščin so pomembne za žlahtniteljske programe. Namen te raziskave je bil določiti povezavo med pridelkom zrnja, stopnjo ekspanzije in drugimi agronomskimi lastnostmi 19 linij pokovke, ovrednoteno v poskusih s ponovitvami na dveh lokacijah. Za določitev povezav med agronomskimi lastnostmi je bila uporabljena korelacijska anliza, za določitev prispevka posameznih agronomskih lastnosti na pridelek zrnja je bila uporabljena multipla postopna regresija. Rezultati so pokazali da so imeli višina rastlin, višina izraščanja storžev in dolžina storžev značilno pozitivno povezavo s pridelkom zrnja. Volumen ekspandiranih zrn je pokazal značilno negativno povezavo (-0,45**) s pridelkom zrnja, masa 100 zrn je imela značilno negativno korelacijo (-0,37**) z volumnom ekspandiranih zrn. Analiza s postopno multiplo regresijo je pokazala, da višina storža na rastlini, njegova dolžina, izgled rastline in masa 100 zrn prispevajo 53,66 % variabilnosti v pridelku zrnja, pri čemer višina storža na rastlini prispeva največji delež (22,51 %). Klasterska analiza je združila linije pokovke v štiri različne grozde, kjer sta bili ‘Small Pearl Shaped’ in ‘Popcorn 33-1-Y’ uvrščeni v II in IV skupino, kar kaže na njuno veliko različnost in možnost uporabe pri tvorbi križancev. Izboljšave pri pokovki bi se morale osredotočiti na prepoznavanju linij s sprejemljivim volumnon ekspandiranih zrn in izboljšanim pridelkom zrnja ter izboljšanimi lastnostmi povezanimi s pridelkom.
