Pridelek in kakovost novega slovenskega križanca koruze pokovke (Zea mays everta Sturt.)

Bednjički, Adelina (author), Rozman, Ludvik (mentor)

V proučevanje je bilo vključenih 6 križancev koruze pokovke, in sicer slovenski križanec koruze pokovke 'PopSkom' in 5 tujih križancev iz žlahtniteljskega inštituta v Gleisdorfu, Avstrija. Namen naloge je bil proučiti pridelek in kakovost novega slovenskega križanca koruze pokovke 'PopSkom' in ju primerjati s petimi tujimi križanci ter ugotoviti kakovost oziroma prostornino gotove pokovke ob določeni vlagi v zrnju. Poskus je bil izveden na dveh lokacijah, in sicer v Jablah pri Ljubljani in v Apačah pri Ptuju po metodi naključnega bloka v treh ponovitvah. Slovenski križanec 'PopSkom' ima belo zrnje, križanci iz Gleisdorfa imajo rumeno. V Apačah je imel največji pridelek najzgodnejši križanec 'PopSkom', v Jablah pa najpoznejši križanec GL-2. Po klasifikaciji Zieglerja (2001) imajo vsi križanci debelo zrnje. Vsebnost vlage v zrnju v vseh proučevanih vzorcih vseh križancev je bila med 11,4 in 15,9 %, prostornina gotove pokovke pa med 350 in 1320 ml na maso 30 g surovega zrnja. Največjo povprečno prostornino gotove pokovke je imel križanec GL-2 (1173,7 ml), najmanjšo pa 'PopSkom' (529,4 ml). Glede na prostornino gotove pokovke vseh vzorcev in vseh križancev v mejah med 12 in 14 % vlage v zrnju v prostornini pokanja ni bilo pomembnih razlik. Zato lahko za proučevane križance sklepamo, da je za optimalno prostornino gotove pokovke najprimernejša vsebnost vlage v zrnju v ugotovljenih mejah.

• Title: Yield and quality of the new Slovenian popcorn hybrid (Zea mays everta Sturt.)

Abstract

The study included 6 popcorn hybrids: the Slovenian popcorn hybrid 'PopSkom' and 5 imported hybrids from the 'Saatzucht, Gleisdorf, Austria. The aim of the investigation was to find out the yield and quality of the new Slovenian popcorn hybrid 'PopSkom' in comparison with five introduced hybrids, and to determine the volume of popping at different grain moisture contents. The experiment was conducted at two locations: at Jable near Ljubljana and at Apače near Ptuj, using the randomised block design in three replications. The Slovenian hybrid 'PopSkom' was characterised by white grains, while the grains of the hybrids from Gleisdorf were yellow. At the Ptuj location, the highest yield was determined for the earliest hybrid 'PopSkom', while at Jable, the most productive was the latest hybrid GL-2. According to the classification of Ziegler (2001) all hybrids had thick grains. The moisture content of the grain in all studied samples of all hybrids ranged between 11.4 and 15.9% and the volume of popping was between 350 and 1320 ml per weight of 30 g of raw grain. The hybrid GL-2 showed the largest average volume of poping (1173.7 ml) and 'PopSkom' the smallest (529.4 ml). Regarding to the volume of the popping of all samples and all hybrids, within the range of the grain moisture between 12 and 14%, there were no significant differences. Taking into account the studied hybrids, we can conclude that these values of grain moisture contents are the most suitable for popping.
