  Maize is currently the single raw material of bio-ethanol production in Hungary. The aim of our examinations is the observation of yield and
  nutritional characteristics of commercial maize hybrids in Hungary from the aspect of efficient bio-ethanol production. We set up a 
  randomized block field trial. We determined the starch content and starch yield (t ha^-1) of the 51 maize hybrids involved in the field trial.
  In laboratory conditions, we examined the amylose and amylopectin ratio and the amount of resistant starch of the selected 20 maize hybrids.
  According to our results, there is a significant difference between the starch yield the amylose component of the starch content and resistant starch of the examined maize hybrids. Our studies reveal that maize as a raw material must be selected based on the cultivation objectives. If the objective is bio-ethanol production, detailed knowledge of starch content is necessary. There is a significant difference among commercial maize hybrids in Hungary in terms of characteristics determining the producible amount of bio-ethanol.

  There are an enormous amount (2-3 million t/yr) of corn surplus is available year by year in Hungary. Inland utilization is an unsolved problem, whereas export facilities of raw (unprocessed) material could not be regarded as optimal way because of logistical barriers and the very low producer’s price. There are two basic opportunities for the export of the surplus of maize with reduced transportational costs and higher value: 
  animal production and process of bio-ethanol. In Hungarian conditions both of them demand the same raw material so they should compete with each other for maize. Both need financial aid at least for the investment in order to reach profit. Decision makers are influenced by several factors in allocating of national supports between the differential branches, one of them could be the added value developing in the given vertical change. I will introduce and analyze the expectable added values of the abovementioned competitive activities.

  The objective of this study was to evaluate the effects of crop year on the main components of maize grown for bio-ethanol production yield, starch content and starch yield per hectare of maize hybrids were investigated in a droughty (2007) and in a favourable years with optimal weather conditions (2008, 2009). We measured very low starch yield (1.5 t ha^-1) in the year with unfavourable precipitation supply (2007) together with higher starch content (73%). In the case of good precipitation supply we measured a much higher starch yield per hectare (7.7 t ha^-1) with lower content (72.4%). In 2009 the starch content (74.5%) exceed the results of the two previous years, but on the other hand the average of starch yield was (4.9 t ha^-1) which falls between the other two years values.
