Maize mythology
(Dr. Márton Jolánkai)
Maize is actually one of the corner stones of the whole agricultural-food sector not only in Hungary but also in most countries of the world. In addition, maize is a unique crop on the one hand for its economic role and on the other for its cultural, even cultic importance. In Mexico, for instance a complete mythology is related to the plant, that may have some lessons to learn also for nowadays’ people.

Maize growing and seed supply in South Africa and Hungary
(Dr. Gábor Barla-Szabó)
You may get the answer to the question how South African maize varieties and the experience of growing them may support the production of those Hungarian hybrids that can give good yields also on less fertile soils, are tolerant to drought and other stress factors, and due to the low moisture content of kernels at harvest, can lower the cost and improve the profitability of maize production.

Lfy-maize hybrids
(Dr. János Pintér, István Pók, Ferenc Rácz, Dr. Zsuzsanna Hegyi, Dr. Géza Hadi, Dr. Csaba L. Marton)
Efforts have been made in almost every breeding places of the world to improve the basic and essential feed of ruminants, i.e. maize silage. One of the most important components of silage maize is leaf that ensures green mass necessary for digestion. A new possibility has opened by patenting the Lfy dominant gene for silage maize breeders in order to use this gene to produce Lfy-hybrids possessing more leaves, recommended only for silage production. The use of Lfy-genes has positive results in the breeding of quality silage hybrids. Furthermore leafy hybrids, due to their huge biomass production per hectare, may supply basic material for the renewing energy production.

The effect of the different weather conditions in 2009 and 2010 on the response of the maize crop to sowing time in Szeged
