Although this paper presented data retrieved from 2 countries from Europe, International experiments have been established in order to examine conventionally bred wheat varieties under different management systems in European organic and conventional fields. So this paper presents an interesting comparative study in the near future.

A Review on the Comparative Study:

Farmers who are following the regulations [Council Regulation (EC) 2007, No. 834/2007] of the rapidly developing organic agriculture (OA) movements have to endeavour to use organic, but the ensuing demand is met in 95 % with organically produced seed from varieties that were bred for conventional agriculture. Conventional plant breeding has mainly relied on selection with strongly limited environmental variability because the selection environment is usually stabilized using artificial fertilizers, herbicides and other chemicals against pests and diseases.

In recent years needs have increased to investigate the necessity of breeding cereals for organic agriculture. The aims of this study were:

  • to compare 37 bread wheat (Triticum aestivum L.) varieties with different breeding origin under low input conventional and certified organic farming conditions in Austria and Hungary for 3 years.
  • to identify traits highly sensitive to management systems that could be separated according to their suggested selecting environments.
  • to find evidence for the distinctness of organic wheat breeding. According to the results, seven out of the 15 traits assessed during this study showed significant management 9 genotype interaction meaning that these traits could be the basis of selection for different management systems.

Based on the assessment of 15 traits through 3 years in 2 countries, the present study has demonstrated the distinctness of organic breeding both in organic and low input fields compared to the common conventional wheat breeding, which showed similar performance to the combined technique of BFOA.

Conventional and BFOA varieties showed great overlapping, because the early generations of the BFOA varieties were selected in a conventional system. These findings could give evidence for that the environment where the selection is carried out has great influence on the traits of bread wheat breeding lines.

Therefore, the organic wheat breeding has resulted in different varieties than the other breeding strategies. However, as the various traits examined in the present study point out the main agronomic and selection differences between the variety-groups bred with different breeding strategies, a more detailed evaluation is planned to be carried out including the compositional and processing quality traits of the studied varieties in the near future.
