The examination of the agronomy, the amount of yield, and the yield stability of winter wheat varieties
Published December 21, 2008
61-72

Our research was carried out at University of Debrecen Centre for Agricultural Sciences Faculty of Agriculture Institution of Plant Sciences Látókép Research Institute through the breeding year of 2003/2004, 2004/2005 and 2005/2006 using cherrnozem soil. In our research we tested 14 chosen autumn wheat varieties during the three crop years.<...br>The different varieties showed very dissimilar ability of resistance against diseases through the three crop years. We could observe both susceptible and resistant varieties. Susceptible varieties got diseases even in favourable crop years. The observed winter wheat varieties showed higher susceptibility against helminthosporium (21.8%) and leaf rost (16.4%). Among the 14 varieties we experienced the least susceptibility in the case of ‘Gaspard’ and ‘GK Kalász’. The research showed that the disease of fusarium undoubtedly depends on the features of the crop year.
In terms of stem solidity we experienced big differences. Among all the observed winter wheat varieties the mid-late ripening ‘Gaspard’ showed the best results in the average of the three years, only 5.3% was beaten down.
The three ripening group of the winter wheat showed the following average yield in the average of three years: 7065 kg/hectare (early ripening varieties), 7261 kg/hectare (late ripening varieties), 6793 kg/hectare (mid-late ripening varieties). Among all the observed varieties the early ripening ‘Flori 2’ produced the biggest yield (7692 kg/hectare).
During the three crop years we reached very different amounts of yield which means that weather conditions had a telling affect on yield. In 2004 we reached an excellent average yield in all the tree  breeding groups because of the favourable weather conditions. In 2005 we had a moderate amount of yield because of the unfavourable weather conditions of winter. The year of 2006 showed the smallest amount of yield which is due to the fact that the plant grew less thick than usually.
There were significant differences among the observed varieties in the term of yield, which can be attributed to dissimilar biological basics.
One of he most important questions is the yield stability of the varieties. We had extremely different results at this field. Speaking in general terms we can state that both weather conditions and genetical abilities have a determining effect on yield. In the case of winter wheat varieties the rate of yield fluctuation was quite big, moving in the interval of 33.7-70.3%. Among all the observed varieties ‘Gaspard’ showed the best yield stability (33.3%).

Evaluating economic value properties of different beetroot varieties
Published May 16, 2017
137-142

The root vegetables have a pivotal role in the vegetable consumption and to form a healthy diet. The consumption of natural juices, like apple-beetroot are becoming more popular and the drying-, the pharmaceutical- and canning industry require more beetroot to process. For the processing, the industry requires easily peeled and round shaped roo...ts, therefore to use the proper variety is very important. The primary quality parameters are the inner color intensity, uniform color and water soluble dry matter content.
4 beetroot varieties were evaluated (Libero, Rubin, Detroit 2 and Cylindra) in the 3 years experiment which was carried out at the University of Debrecen, Institutes for Agricultural Research and Educational Farm, Botanical and Exhibiton Garden. The soil type was calcareous chernozem. Leaf length, shape index and water soluble solid content were measured, and sensory evaluation was carried out on taste, inner color intensity and white ring.
To summarize, we can state the exception of Rubin genotype all of the varieties are suitable for second cultivation and good for processing (canned, juice, powder).

Evaluation of mineral element content of beetroot during the different stages of the growing season
Published September 5, 2018
459-537

In modern nutrition, bioactive materials of different vegetables are especially important to be researched. The experiment was carried out on March 30, 2016 (sowing date). Mineral element content (B, Ca, Cu, Fe, K, Mg, Na, P, S, Zn) was evaluated on the 60th, 85th and the 105th day of the vegetation period. The data are presented as the mean of... five varieties which can give the real state of these parameters of beetroot grown on lowland chernozem soil.

In the young beetroot leaves (60 days) the mineral element content was higher than in the older ones (85 days). The calcium and magnesium content of the leaves was much more favourable (10 times higher) than in the root. The potassium content of leaves has reached the amount of 5000 mg kg-1, but at the same time more than 3000 mg kg-1 was detected in the improved root. This value is favourable for the potassium supply of the human organism.

The sulphur content (1300 mg kg-1) of the leaves was the highest on the 85th day of vegetation period. Similar tendency was detected for boron content (2.45 mg kg-1), while for iron content it was higher (28.23 mg kg-1) in the younger leaves (60 days).

Finally, it can be concluded that the increased element content of beetroot leaves will be a favourable source of mineral element supply of the human organism.
